General Description
The HMC442 is an efficient GaAs PHEMT MMIC
Medium Power Amplifier which operates between
17.5 and 25.5 GHz. The HMC442 provides 15 dB of
gain, +23 dBm of saturated power and 25% PAE from
a +5V supply voltage. The amplifier chip can easily be
integrated into Multi-Chip-Modules (MCMs) due to its
small size. All data is tested with the chip in a 50 Ohm
test fixture connected via 0.025mm (1 mil) diameter
wire bonds of minimal length 0.31mm (12 mils).
