TAMP-362LN+ Overview
A low-noise amplifier (LNA) is a specialized RF amplifier placed at the very front end of a receiver chain to add the least possible noise to a weak incoming signal before subsequent gain stages. LNAs sit within the broader taxonomy of RF amplifier -> amplifier IC/module -> RF & microwave -> active semiconductor device. Their position immediately after the antenna makes their noise figure the dominant contributor to the receiver's overall noise performance, so a sub-1 dB NF is the key figure of merit for 3.3-3.6 GHz sub-6 GHz radios.
The TAMP-362LN+ utilizes advanced HJ-FET (Heterojunction Field-Effect Transistor) technology in a single-stage topology, packaged in a drop-in shielded case that requires no external matching components. Its high output IP3 provides strong linearity for handling modulated signals such as LTE, 5G NR n78, and Wi-Fi 6E carriers. The integrated bias and stabilization networks simplify PCB layout and reduce the bill of materials compared with discrete LNA designs.
Typical applications include 3.5 GHz fixed wireless access (FWA), small-cell base-station receiver front ends, satellite communications L-band block-converter IF chains, and public-safety / WiMAX infrastructure. The module's compact shielded footprint also supports phased-array and MIMO radio designs where board area is at a premium.
When designing with the TAMP-362LN+, follow Mini-Circuits' recommended PCB land pattern and place decoupling capacitors close to the DC feed pin to preserve stability. Ensure the 50 Ω interconnect transitions are kept short and impedance-controlled to avoid degrading the 1.3:1 VSWR specification.

Typical Applications
TAMP-362LN+ is suitable for 6 applications: 5G NR n78 / CBRS Small-Cell Receiver Front End, Fixed Wireless Access (FWA) Customer-Premises Equipment, L-Band / S-Band Satellite-Communications Block Down-Converter IF, Public-Safety / WiMAX / LTE Band 42-43 Infrastructure, Phased-Array and MIMO Radio Receiver Elements, Test & Measurement Down-Converter Front End.
5G NR n78 / CBRS Small-Cell Receiver Front End
The TAMP-362LN+ is a strong match for 5G NR n78 (3300-3800 MHz) and CBRS (3550-3700 MHz) small-cell receiver front ends because its 0.9 dB typical noise figure maximises uplink sensitivity and its 3300-3600 MHz band covers the operator-deployed sub-band. With 12 dB of gain the LNA overcomes PCB and filter losses upstream of the down-converter, while a +5 V at 20 mA bias keeps total front-end power within tight small-cell thermal budgets. Designers typically place the module between the antenna diplexer and the first mixer, using the drop-in shielded module to avoid RF tuning work in the radio. Compared with a discrete HJ-FET LNA, the integrated matching and bias networks reduce board area and BOM cost for high-volume small-cell production.

Fixed Wireless Access (FWA) Customer-Premises Equipment
For FWA customer-premises equipment (CPE) radios that receive a 3.5 GHz downlink from a nearby base station, the TAMP-362LN+ delivers the 0.9 dB noise figure needed to maintain link margin over long wireless paths. Its 12 dB gain overcomes the insertion loss of a diplexer or bandpass filter typically placed between the antenna and LNA, and the 20 mA bias is friendly to Power-over-Ethernet powered CPE designs. The drop-in SMT module footprint supports automated high-volume assembly, which is critical for residential and SME FWA gateways shipped in volume. The 1.3:1 typical VSWR simplifies matching to the printed antenna or diplexer feed, reducing the risk of receiver desensitisation from return-loss interactions.
Recommended
L-Band / S-Band Satellite-Communications Block Down-Converter IF
In block down-converter IF chains for satellite ground equipment, the TAMP-362LN+ provides 12 dB of low-noise gain at 3.5 GHz to overcome the noise contribution of subsequent filter and mixer stages. The 0.9 dB typical NF preserves overall receiver noise temperature, which is critical for low-rate telemetry and VSAT terminals receiving weak satellite beacons. The shielded case prevents local oscillator leakage into the antenna path, and the drop-in 0.591" x 0.394" footprint supports dense PCB layouts. Per the Mini-Circuits datasheet the part operates from a single +5 V rail, easing integration into existing L-band and S-band receiver chassis.
Recommended
Public-Safety / WiMAX / LTE Band 42-43 Infrastructure
WiMAX, LTE band 42/43, and 3.5 GHz public-safety radio infrastructure operating from 3300-3600 MHz benefits from the TAMP-362LN+'s combination of sub-1 dB noise figure, 12 dB gain, and good linearity. The drop-in module simplifies radio-front-end design for OEM base-station and repeater products, while the 50 Ω input and output match seamlessly with standard bandpass filters and isolators. The single +5 V bias reduces power-converter complexity in sealed outdoor enclosures. Per the Mini-Circuits datasheet the integrated bias and stabilization networks ensure unconditional stability into VSWR loads typical of duplexer-fed antenna ports.
Recommended
Phased-Array and MIMO Radio Receiver Elements
Massive MIMO and phased-array receivers operating at 3.5 GHz allocate one LNA per antenna element, where compact size and repeatable RF performance are essential. The TAMP-362LN+ drop-in SMT module footprint (0.591" x 0.394") fits alongside a 64- or 128-element array, and the integrated matching and shielding make per-element gain and noise figure uniform across the array. The 0.9 dB noise figure maximises beamforming sensitivity, while the 12 dB gain drives subsequent digital beamforming ASICs directly. With +5 V at 20 mA the thermal load per element is moderate, enabling dense array layouts without active cooling.
Recommended
Test & Measurement Down-Converter Front End
Lab and production test equipment such as spectrum-analyser down-converters and signal-generator reference chains benefit from the TAMP-362LN+'s low 0.9 dB noise figure at 3.5 GHz, which improves the noise floor and dynamic range of measurement instruments. The 12 dB gain overcomes cable and connector losses when interfacing to DUTs through long test leads. Drop-in shielded packaging means the LNA module can be added as an outboard accessory to existing instruments without redesigning the RF chain. The +5 V single-rail bias works with standard instrument power rails, simplifying integration into automated test racks.

Key Differentiators
- Sub-1 dB noise figure at 3.3-3.6 GHz in a drop-in module (vs TAMP-362GLN+)
- Integrated matching and bias - no external RF tuning (vs Discrete HJ-FET LNA transistor + external matching)
- Standard 0.591" x 0.394" SMT LNA footprint enables drop-in upgrades (vs TAMP-362GLN+ (Tape & Reel))
Design Notes
Follow the Mini-Circuits reference PCB land pattern for the shielded SMT LNA module exactly. Keep the 50 Ω microstrip or grounded-coplanar waveguide transitions as short as possible between the antenna/diplexer and the LNA RF pads; the 1.3:1 typical VSWR budget can easily be lost to a mismatched interconnect exceeding a few mm at 3.5 GHz. Place the +5 V bypass capacitor (typically 100 pF + 10 nF + 1 µF) directly at the DC feed pad to prevent gain ripple and oscillation.
The shielded SMT case must be soldered to a continuous top-layer ground pour with multiple stitching vias around the perimeter to suppress cavity resonances and common-mode radiation. Avoid routing any digital or noisy DC traces beneath the LNA footprint - those traces couple directly into the RF pads and degrade NF. Where space allows, place a pi-attenuator or matching pad network after the LNA for gain adjustment and inter-stage VSWR improvement.
Estimated: Cascaded noise figure with a 3 dB pad in front of the TAMP-362LN+ (input 12 dB gain, 0.9 dB NF): Friis NF_total = 3 dB + (0.9 dB - 3 dB) / (10^(12/10)) ≈ 3.18 dB, so external attenuation before the LNA quickly destroys the noise advantage. Keep the diplexer or filter loss in front of the LNA below ~1 dB. Also verify the +5 V rail is low-noise - a switching converter with >20 mV ripple will modulate the LNA bias and appear as spurious on the output.
At +5 V and 20 mA the TAMP-362LN+ dissipates only 100 mW, so no heatsinking is required. Verify in a sealed outdoor enclosure that the ambient temperature around the shielded module stays within the Mini-Circuits operating range to maintain NF and gain specifications. For Hi-Rel or screening variants, derate the maximum ambient by 10-15 °C for long-term reliability.
Compliance Information
RoHS compliance is explicitly stated on the Mini-Circuits datasheet. AEC-Q100 is not applicable (RF module, not automotive IC). REACH compliance assumed by EU distribution but not explicitly stated in the verified web data; halogen-free and conflict-mineral status flagged as 'unknown' because no source string in the verified data confirms them.
