HMC486

v03.0109

General Description

Features

Functional Diagram

The HMC486 is a high dynamic range GaAs PHEMT

MMIC 2 Watt Power Amplifier which operates from 7

to 9 GHz. This amplifier die provides 26 dB of gain,

+34 dBm of saturated power and 24% PAE from a +7V

supply voltage. Output IP3 is +40 dBm typical. 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 0.025mm (1 mil) diameter wire bonds of

minimal length 0.31mm (12 mils).

Saturated Output Power: +34 dBm @ 24% PAE

Output IP3: +40 dBm

Gain: 26 dB

DC Supply: +7 V @ 1300 mA

50 Ohm Matched Input/Output

Die Size: 2.51 x 2.51 x 0.1 mm

Typical Applications

The HMC486 is ideal for use as a power amplifier for:

• Point-to-Point Radios

• Point-to-Multi-Point Radios

• Test Equipment & Sensors

• Military End-Use

• Space
