TB-TAMP-362LN+ 概述
An RF low-noise amplifier (LNA) is a specialized active component that boosts very small antenna-received signals with minimal added noise, establishing the noise floor of the entire receive chain. LNAs belong to the broader category of RF amplifier ICs/modules, which sit in the signal chain hierarchy of antenna -> LNA -> filter -> mixer -> IF/baseband. Mini-Circuits is a leading supplier of drop-in coaxial and SMT amplifier modules that integrate bias, matching, and stabilization into a single shielded package.
The TAMP-362LN+ utilizes HJ-FET (Hetero-Junction FET) technology in a single-stage topology, achieving 0.9 dB typical noise figure, 12 dB gain with +/-0.4 to +/-0.8 dB gain flatness across the band, and 1.3:1 typical VSWR for both input and output. Output P1dB is 7 dBm to 11 dBm, making the device suitable as a first-stage receive amplifier in front of a moderate-IP3 mixer.
The integrated shielded case eliminates the need for external RF matching networks, allowing engineers to drop the part onto a 50 ohm microstrip trace and supply +5 V through a single bias pin. The low 20 mA quiescent current eases DC budget constraints in remote radio heads, small cells, and satellite terminals where thermal management is critical.
Typical applications include 3.5 GHz WiMAX front ends, CBRS (Citizens Broadband Radio Service) infrastructure, small-cell and femtocell receivers, point-to-point microwave links, and satellite communication LNBs operating in the 3.3 to 3.6 GHz band. When laying out the PCB, place the amplifier as close to the antenna/filter as possible to preserve noise figure, and use 50 ohm controlled-impedance traces on both RF pins.

典型应用
TB-TAMP-362LN+ 适用于 6 应用s: 3.5 GHz WiMAX Front-End Receiver, CBRS Small-Cell Infrastructure, Point-to-Point Microwave Link Receiver, Satellite Communication LNB Front-End, Test and Measurement Instrumentation, Military and Aerospace Radio Systems.
3.5 GHz WiMAX Front-End Receiver
The TAMP-362LN+ serves as the first-stage receive LNA in 3.5 GHz WiMAX subscriber stations and base stations. Its 0.9 dB typical noise figure sets the receiver sensitivity floor, while 12 dB gain overcomes the PCB trace and filter losses ahead of the mixer. The integrated matching eliminates external tuning, accelerating time-to-market for fixed WiMAX CPE designs.
推荐
CBRS Small-Cell Infrastructure
The 3.3 to 3.6 GHz TAMP-362LN+ is well matched to Citizens Broadband Radio Service (CBRS) small-cell and femtocell receivers. Its 0.9 dB NF maximizes uplink sensitivity for shared 3.5 GHz spectrum, and the 20 mA current supports dense small-cell deployments with constrained power budgets. The shielded SMT case simplifies outdoor radio unit design.
推荐
Point-to-Point Microwave Link Receiver
In FDD or TDD point-to-point microwave links operating at 3.5 GHz, the TAMP-362LN+ provides low-noise pre-amplification for the receiver front-end, with 12 dB gain and 1.3:1 VSWR protecting system gain flatness. The 50 ohm matched interface drops directly into standard PTP radio PCBs, minimizing BOM and tuning time for backhaul equipment.
推荐
Satellite Communication LNB Front-End
For 3.5 GHz satellite uplink/downlink terminals, the TAMP-362LN+ serves as a low-noise pre-amplifier ahead of the downconverter. Its 0.9 dB NF preserves G/T figure-of-merit critical for VSAT and portable satcom antennas. The shielded case provides EMI isolation from onboard digital circuitry common in modem-integrated terminals.
推荐
Test and Measurement Instrumentation
Lab bench RF instrumentation such as spectrum analyzer front-ends and signal generator pre-amplifiers benefit from the TAMP-362LN+'s 0.9 dB NF and 12 dB flat gain across 3.3 to 3.6 GHz. The drop-in 50 ohm module eliminates custom matching design work, allowing test equipment designers to focus on calibration and DSP rather than RF front-end tuning.
推荐
Military and Aerospace Radio Systems
Defense and aerospace radio systems operating in the 3.5 GHz band use the TAMP-362LN+ as a rugged, low-noise receive pre-amplifier. The shielded SMT case withstands harsh EMI environments, and the 0.9 dB NF maximizes detection range for tactical communications. The wide operating temperature range supports outdoor and avionics deployment.

关键差异点
- Ultra-low 0.9 dB noise figure with only 20 mA supply current （对比 TAMP-362GLN+)
- Drop-in shielded SMT package with internal matching （对比 TAMP-362LMN+)
- Single-stage HJ-FET topology optimized for lowest NF （对比 TAMP-362GLN+)
设计说明
Place the TAMP-362LN+ as close as physically possible to the antenna or RF input filter to minimize trace loss before the LNA, since the LNA's 0.9 dB noise figure is meaningless if 1 dB of trace loss precedes it. Use 50 ohm controlled-impedance microstrip or coplanar waveguide on both RF-IN and RF-OUT. Keep the bias feed line (VCC) short and decoupled with a 100 pF and 10 nF capacitor pair to prevent RF leakage into the DC rail.
Estimated: at +5 V and 20 mA typical, the TAMP-362LN+ dissipates about 100 mW, which is well within the shielded case thermal rating. In sealed outdoor enclosures with no airflow, ensure the case ground plane has thermal vias to an inner copper layer to spread heat; the device does not require an external heatsink in normal 3.5 GHz receiver operation.
Do not exceed +5.25 V on the VCC pin or the HJ-FET may degrade. Avoid bending the SMT leads during reflow - the shielded case is fragile at the RF pin transitions. Do not place digital switching signals or noisy DC-DC converters within 5 mm of the case, as the integrated shielding can still couple EMI through the RF pins if the trace impedance is mismatched.
Surround the TAMP-362LN+ with a continuous ground pour on the top layer tied to the case ground pin, with multiple stitched vias to the inner ground plane. Keep the RF-IN and RF-OUT traces perpendicular to each other if possible, and avoid running them under the case where they could couple into the bias network. The Mini-Circuits evaluation board layout is the recommended starting reference.
