What are the key features of HMC485AMS8GETR?
- High input third-order intercept point (IIP3) of +17 dBm typical enables operation in dense multi-carrier environments without significant intermodulation distortion
- Wideband DC to 4 GHz RF and LO frequency range in a single MMIC covers S-band radar, ISM, and wideband communications without external matching networks
- Compact 8-pin MSOP package measures 3 mm × 3 mm, reducing the PCB footprint versus surface-mount hybrid mixers by more than 60% in microwave front-end assemblies
What is HMC485AMS8GETR used for?
HMC485AMS8GETR is designed for microwave receiver and transmitter front-ends in test instrumentation, point-to-point radio, and military EW systems operating across the DC to 4 GHz band. Its high linearity suits multi-channel base-station and software-defined radio platforms where third-order intermodulation must remain below –60 dBc at standard signal levels. The device also serves as an upconverter in ISM-band modules and 2.4 GHz to 4 GHz frequency translation circuits requiring minimal gain compression.

Frequently Asked Questions
What LO drive level does HMC485AMS8GETR require, and how does it affect system design?
HMC485AMS8GETR requires a nominal LO drive of +7 dBm for specified performance. This low LO power allows the device to be driven directly from a low-output VCO or frequency synthesizer without an additional buffer amplifier, reducing the component count and saving approximately 50 mW of supply power in portable radio designs.
How does HMC485AMS8GETR's IIP3 compare to a passive diode-ring mixer in a 2.4 GHz receiver?
HMC485AMS8GETR achieves a typical IIP3 of +17 dBm in the 2.4 GHz band, which is comparable to discrete Schottky diode-ring mixers that typically reach +15 dBm to +20 dBm. The MMIC integrates the matching and balun structures in 3 mm × 3 mm MSOP, eliminating the 4–6 external components a diode-ring topology requires and reducing assembly variation at volume production.
Can HMC485AMS8GETR be used in an S-band radar receiver, and what conversion loss should the noise-figure budget assume?
Yes, HMC485AMS8GETR covers the full S-band from 2 GHz to 4 GHz within its DC-to-4 GHz specified range. The typical conversion loss is 6.5 dB, so the system noise-figure budget should allocate this value for the mixer stage. With a 15 dB LNA preceding the mixer, the cascaded noise figure contribution from HMC485AMS8GETR drops to approximately 0.8 dB, consistent with a sub-3 dB overall receiver noise figure.
