HMC558ALC3BTR-R5 Présentation
A double-balanced mixer is a passive or active frequency-conversion stage that multiplies a radio-frequency (RF) input by a local oscillator (LO) signal to produce sum and difference intermediate-frequency (IF) products while suppressing certain spurious responses. In the receiver chain hierarchy, a mixer sits between the low-noise amplifier and the IF/baseband stage, while in the transmitter chain it sits between the baseband modulator and the power amplifier. Double-balanced topologies employ two transformers or baluns to provide inherent LO-to-RF and LO-to-IF port isolation, which is critical for dense multi-converter designs where LO leakage would otherwise leak into adjacent channels.
Key features of the HMC558A include wide RF/LO bandwidth (5.5 GHz to 14 GHz), typical input IP3 of +17 dBm, typical LO-to-RF isolation of 35 dB, and a passive GaAs MESFET Schottky-diode topology that needs no DC bias. The leadless ceramic SMT package is compatible with standard reflow profiles and offers repeatable performance up to 14 GHz, an advantage over chip-on-board solutions for production volumes.
Architecturally, the HMC558A is fabricated in a GaAs metal-semiconductor field-effect transistor (MESFET) Schottky-barrier diode process, an Analog Devices Hittite Microwave heritage technology chosen for low conversion loss and high linearity at microwave frequencies. The double-balanced diode quad, driven by an on-chip balun, provides symmetrical port isolation without external hybrids.
Typical applications include 5.5-14 GHz point-to-point and point-to-multipoint radios, C-band and Ku-band downlinks, microwave backhaul upconverters, electronic warfare (EW) receiver front ends, and radar IF strips. The wide bandwidth also covers unlicensed 5 GHz ISM and U-NII bands plus portions of the 6 GHz and 7 GHz microwave links.
When designing with this mixer, ensure the LO drive level meets the +13 dBm typical recommended input so that conversion loss and port-to-port isolation stay within datasheet limits. Use low-loss PCB substrates (e.g., Rogers RO4003C) above 10 GHz and keep the LO trace short to suppress feedthrough.

Applications typiques
HMC558ALC3BTR-R5 convient pour 6 applications: 5.5-14 GHz Microwave Backhaul Up/Downconverter, Ku-Band Satellite Downlink Front End, Electronic Warfare (EW) Receiver Front End, C-Band Radar IF Strip, 5 GHz / 6 GHz Unlicensed-Band Transceiver, Test & Measurement Microwave Downconverter.
5.5-14 GHz Microwave Backhaul Up/Downconverter
The HMC558ALC3BTR-R5's 5.5-14 GHz RF/LO bandwidth and 8 dB typical conversion loss make it well suited for microwave backhaul radios used in point-to-point and small-cell fronthaul links. Its passive GaAs MESFET design needs no DC bias, simplifying the outdoor radio enclosure thermal design. With +17 dBm input IP3 the mixer tolerates strong adjacent-channel blockers common in dense urban backhaul deployments. Mounted between the PA/LNA stage and the IF/baseband modem, it shifts the 6 GHz, 7 GHz, 10 GHz, 11 GHz, 13 GHz, or 15 GHz E-band-adjacent carriers down to a low IF for digital demodulation, or up from baseband to RF for transmit. Low LO-to-RF isolation (35 dB typical) keeps the LO leakage below the receiver noise floor even when sharing a common LO distribution with neighbor radios.

Ku-Band Satellite Downlink Front End
The HMC558ALC3BTR-R5 supports the 10.7-12.75 GHz Ku-band downlink segment with its 5.5-14 GHz RF range, letting designers pair it with a low-noise block (LNB) and IF strip in VSAT terminals. The double-balanced topology suppresses LO leakage into the LNA, preserving the receive system noise figure. Its leadless 12-CLCC package survives outdoor temperature swings (-40 C to +85 C operating range) and reflow assembly for high-volume consumer broadband production. With no DC bias requirement, the mixer can be placed close to the waveguide probe to minimize microstrip insertion loss above 10 GHz. Designers should pair the part with a low-phase-noise dielectric resonator oscillator (DRO) to keep the LO sidebands out of the satellite transponder passband.
Recommandé
Electronic Warfare (EW) Receiver Front End
Wideband electronic-warfare receivers need mixers that span multiple radar bands without retuning, which the HMC558ALC3BTR-R5 delivers across 5.5-14 GHz in a single stage. Its +17 dBm input IP3 tolerates the simultaneous-signal environments typical in threat-warning and ELINT receivers. The double-balanced diode quad provides inherent LO suppression, critical when the EW front end must detect low-RF signals with the LO sitting in-band. Because the mixer is passive, it adds no 1/f noise and preserves the fast-sweep capability demanded by frequency-agile radar intercept receivers. Designers often pair the HMC558ALC3BTR-R5 with a fast-hopping YIG or DDS LO to scan multiple GHz of spectrum in microseconds.
Recommandé
C-Band Radar IF Strip
The HMC558ALC3BTR-R5 covers the 5.25-5.85 GHz C-band radar segment, making it useful in marine and weather-radar IF conversion stages where double-balanced mixer performance is required. With 35 dB LO-to-RF isolation, the radar's local oscillator does not leak back into the antenna feed, which would otherwise degrade the radar's minimum detectable signal. The passive design also eliminates the DC supply noise that an active mixer would inject into the IF strip, important for pulse-Doppler processing where FFT dynamic range matters. Its 12-CLCC SMT package allows dense PCB layout in compact radar modules used on unmanned aerial vehicles (UAVs).

5 GHz / 6 GHz Unlicensed-Band Transceiver
The lower edge of the HMC558ALC3BTR-R5's range covers the 5.15-5.85 GHz U-NII and 5.725-5.875 GHz ISM bands used by Wi-Fi 5/6/6E, point-to-point FWA, and public-safety radios. Using a 5 GHz mixer in a double-balanced topology achieves the LO suppression needed for compliance with FCC spurious-emission masks in dense 5 GHz deployments. The leadless SMT package supports high-volume reflow assembly on standard FR-4 boards at the lower end of the band, reducing BoM cost versus ceramic-substrate solutions. With 8 dB conversion loss, designers can place a 10 dB LNA in front of the mixer and still meet the receiver's overall noise figure target at 5 GHz.
Recommandé
Test & Measurement Microwave Downconverter
Bench-top spectrum analyzers and signal analyzers in the 5.5-14 GHz range often use a passive double-balanced mixer as the final downconversion stage before the ADC. The HMC558ALC3BTR-R5's wide RF/LO range and 8 dB conversion loss make it a good fit for a multi-octave downconverter card that can be reused across multiple product families. Its +17 dBm IP3 keeps measurement integrity when probing higher-power signals typical in production-line ATE. Because the mixer is passive, it does not drift with temperature or supply variations, so the analyzer's amplitude accuracy stays within spec across the full operating-temperature range. Designers using the HMC558ALC3BTR-R5 in test gear should pair it with a precision LO source to keep the conversion-loss calibration table accurate.

Notes de conception
Use a low-loss microwave substrate such as Rogers RO4003C (Er=3.55) for the RF, LO, and IF traces when operating above 10 GHz. Estimated: with RO4003C 8-mil substrate, microstrip loss at 12 GHz is about 0.45 dB/inch, keeping the 8 dB typical conversion loss within budget. Maintain 50-ohm trace impedance (about 1.85 mm wide on 8-mil RO4003C) and use ground-via stitching every quarter wavelength to suppress slot-line modes.
Place the HMC558ALC3BTR-R5 directly at the LO/RF/IF trace junctions and minimize stub length to keep parasitic inductance below 0.5 nH. Keep the exposed pad (package bottom) soldered to a continuous ground plane with at least 9 thermal/ground vias (3x3 array, 0.3 mm drill) to maintain package grounding and thermal dissipation. Use coplanar waveguide with ground (CPWG) layout for the top layer to suppress substrate modes above 10 GHz.
The HMC558ALC3BTR-R5 is a passive mixer and requires no DC supply, but the LO drive must be held at the datasheet's recommended +13 dBm level for the 8 dB conversion-loss and 35 dB LO-RF isolation figures to hold. Under-driving the LO degrades conversion loss by 1-2 dB and reduces port isolation. Above +18 dBm LO drive, the GaAs Schottky diode quad may compress. Always include a 3 dB pad on the LO input if your source can exceed +15 dBm.
