DC-6 GHZ SiGe gain blocks

27 July 2005 Analogue, Mixed Signal, LSI

Hittite Microwave has released a SiGe HBT gain block MMIC amplifier for use in cellular/3G, FWA, CATV, microwave radio and test equipment applications from DC to 6 GHz. The HMC474MP86 is a general-purpose SMT amplifier (micro-P packaged) that can be used as a cascadable 50 Ω RF/IF gain stage with 15,5 dB gain and up to +11 dBm saturated output power. It delivers an output IP3 of +22 dBm at 850 MHz, while operating from a single positive supply as low as 3 V, and consuming only 25 mA. The Darlington feedback pair topology results in superior gain stability over temperature and it requires no external matching components.
