Gain blocks feature low noise figure

The HMC636ST89E/HMC639ST89E GaAs pHEMT based gain block amplifiers require no external matching — making them ideal as replacements for competitor products such as the AH-1 and the AM-1 gain blocks in IF and RF applications from 50 MHz to 4 GHz. The HMC636ST89E is rated from 200 MHz to 4 GHz, and delivers 13-dB gain, 40-dBm output IP3, and 2.2-dB noise figure.

The HMC639ST89E is rated from 50 MHz to 3 GHz, and delivers 13-dB gain, 38-dBm output IP3, and 2.7-dB noise figure. The HMC636ST89E and HMC639ST89E are powered directly from a 5-V supply and consume 155 mA and 104 mA of current respectively. (Ea/99: HMC636ST89E, $2.90; HMC639ST89E, $2.92 — available now.)
