The HMC589ST89 & HMC589ST89E are InGaP HBT Gain Block MMIC SMT amplifiers covering DC to 4 GHz and packaged in an industry standard SOT89. The amplifier can be used as a cascadable 50 Ohm RF or IF gain stage as well as a LO or PA driver with up to +19 dBm P1dB output power for cellular/3G, FWA, CATV, microwave radio and test equipment applications. The HMC589ST89(E) offers 20 dB gain and +33 dBm output IP3 at 1 GHz while requiring only 82 mA from a single positive supply. The HMC589ST89(E) InGaP HBT gain block offers excellent output power and gain stability over temperature.
