HMC273AMS10GETR

HMC273AMS10GETR is a broadband GaAs MMIC amplifier from Analog Devices (Hittite). It is a 50-ohm, RF-front-end amplifier designed for microwave/millimeter applications and comes in the AMS10 10-pin MSOP-style package (3x3 mm, RoHS compliant). The device provides input and output matched to 50 Ω and requires external biasing (Vdd) with RF bypassing; exact biasing, current, and operating frequency range are specified in the datasheet and evaluation board guides.
Typical uses include LNA/driver stages in wireless, radar, SATCOM, and instrumentation front-ends. How to use:
- Provide proper bias per the datasheet and include RF decoupling as recommended.
- Use a 50 Ω RF layout with appropriate grounding and vias.
- Employ the recommended external matching only if you need performance beyond the standard 50 Ω interface.
For precise specs (frequency range, gain, noise figure, IP3, quiescent current) and pinout, consult the HMC273AMS10GETR datasheet and evaluation board documents.

Direct equivalents for HMC273AMS10GETR aren’t published as a single cross-reference. To cross-reference, compare specs and packaging. Potential substitutes within Analog Devices/Hittite include other HMC273 variants in MSOP-10 with similar frequency ranges and LO/DC specs; outside vendors (Skyworks, Qorvo, Mini-Circuits) offer similar RF mixers with matching IF. For an exact cross, provide operating frequency, LO drive, IF bandwidth, and package, or use distributor cross-reference tools.
