Features

Typical Applications

General Description

The HMC451 is a general purpose GaAs PHEMT

MMIC Medium Power Amplifier which operates

between 5 and 20 GHz. The amplifier provides

22 dB of gain, +22 dBm of saturated power at 24%

PAE from a +5V supply. Consistent gain and output

power across the operating band make it possible to

use a common driver/LO amplifier approach in mul-

tiple radio bands. The HMC451 amplifier can easily

be integrated into Multi-Chip-Modules (MCMs) due

and DC blocked I/Os. 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).

Gain: 22 dB

Saturated Output Power: +22 dBm @ 24% PAE

Output IP3: +30 dBm

Single Positive Supply: +5V @ 127mA

50 Ohm Matched Input/Output

Small Size: 1.27 x 1.27 x 0.1 mm

The HMC451 is ideal for use as a driver amplifier for:

• Point-to-Point Radios

• Point-to-Multi-Point Radios & VSAT

• Test Equipment & Sensors

• LO Driver for HMC Mixers

• Military & Space
