General Description
The HMC864 is a three stage GaAs pHEMT MMIC
1 Watt Power Amplifier which operates between
24 and 29.5 GHz. The HMC864 provides 27 dB of
gain, and +31 dBm of saturated output power and
18% PAE from a +6V supply. The RF I/Os are DC
blocked and matched to 50 Ohms for ease of integra-
tion into Multi-Chip-Modules (MCMs). All data is taken
with the chip in a 50 Ohm test fixture connected via
0.025 mm (1 mil) diameter wire bonds of length 0.31
mm (12 mils).
Electrical Specifications, T_A = +25° C, Vdd = Vdd1 = Vdd2 = +6V, Idd = 750mA ^[1]
