The HMC1131 reduces the number of components required to achieve the desired output power and small-signal gain in civil and defence communications systems, including point-to-point radios, point-to-multipoint radios, VSAT, and SATCOM. Based on a GaAs pHEMT design, the MMIC amplifier requires 225 mA from a 5V supply. Return loss is 8 dB (input) and 7 dB (output) typical. Gain variation over temperature is 0.031 dB/°C.
Housed in a 4×4-mm, 24-lead ceramic leadless chip carrier, the HMC1131 distributed driver amplifier costs $34.15 (1000); an evaluation board, the EV1HMC1131LC4, costs $248.60.
