Hittite Microwave’s HMC636ST89E and HMC639ST89E GaAs pHEMT MMIC gain block amplifiers perform in automotive, broadband, CATV, cellular/3G, WiMAX/4G and fixed wireless applications from 50 MHz to 4 GHz. The HMC636ST89E delivers 13 dB gain, 40 dBm output IP3, and noise figure of 2.2 dB while being rated from 200 MHz to 4 GHz and consuming 155 mA. The HMC639ST89E offers 13 dB gain, +38 dBm output IP3, and noise figure as low as 2.7 dB while being rated from 50 MHz to 3 GHz and consuming 104 mA. The 50 Ω cascadable amplifiers run from 5 V supply in RoHS-compliant SMT SOT89 packages.
