General Description
The HMC757 is a three stage GaAs pHEMT MMIC 1/2
Watt Power Amplifier which operates between 16 and
24 GHz. The HMC757 provides 22 dB of gain, and +30
dBm of saturated output power at 30% PAE from a
+7V supply. The RF I/Os are DC blocked and matched
to 50 Ohms for ease of integration 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).
