Features

Typical Applications

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).

Saturated Power: +23 dBm @ 25% PAE

Gain: 15 dB

Supply Voltage: +5V

50 Ohm Matched Input/Output

Die Size: 1.03 x 1.13 x 0.1 mm

The HMC442 is ideal for use as a medium power

amplifier for:

• Point-to-Point and Point-to-Multi-Point Radios

• VSAT
