HMC442

GaAs PHEMT MMIC MEDIUM

POWER AMPLIFIER, 17.5 - 25.5 GHz

v01.0304

General Description

Features

Functional Diagram

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 +5.0 V supply voltage. The amplifier

chip can easily be integrated into Multi-Chip-

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: +5.0 V

50 Ohm Matched Input/Output

Typical Applications

The HMC442 is ideal for use as a medium power

amplifier for:

• Point-to-Point Radios

• Point-to-Multi-Point Radios

• VSAT
