General Description
The HMC451 is a general purpose GaAs PHEMT
MMIC Medium Power Amplier which operates
between 5 and 20 GHz. The amplier 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 amplier approach in mul-
tiple radio bands. The HMC451 amplier can easily
be integrated into Multi-Chip-Modules (MCMs) due
to its small (1.61mm
2
) size, single supply operation
and DC blocked I/Os. All data is tested with the chip
in a 50 Ohm test xture 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

The HMC451 is ideal for use as a driver amplier for:
• Point-to-Point Radios
• Point-to-Multi-Point Radios & VSAT
• Test Equipment & Sensors
• LO Driver for HMC Mixers
• Military & Space
