Functional Diagram
General Description
The HMC442 is an ef鏗乧ient GaAs PHEMT MMIC
Medium Power Ampli鏗乪r 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 +5.0 V supply voltage. The ampli鏗乪r
chip can easily be integrated into Multi-Chip-
Modules (MCMs) due to its small (0.96mm
2
) size.
All data is tested with the chip in a 50 Ohm test
鏗亁ture connected via 0.025mm (1 mil) diameter
wire bonds of minimal length 0.31mm (12 mils).
