The self-biased amplifi er provides 13 dB of gain, to dB noise fi gure and + dBm of output power at 1 dB pression while requiring only 66 mA from a single +5V supply. Gain fl atness is excellent from 6 - 18 GHz making the HMC462LP5 & HMC462LP5E ideal for EW, ECM RADAR and test equipment applications. The wideband amplifi er I/Os are internally matched to 50 Ohms and are internally DC blocked.
