Functional Diagram
General Description
The HMC-AUH312 is a GaAs MMIC HEMT Distrib-
uted Driver Amplifier die which operates between
500 MHz and 65 GHz and provides a typical 3
dB bandwidth in excess of 65 GHz. The amplifier
provides 10 dB of small signal gain and a maximum
output amplitude of 2.5V peak to peak, which makes it
ideal for use in broadband wireless, fiber optic commu-
nication and test equipment applications. The amplifier
die occupies 1.2 mm2 which facilitates easy integration
into Multi-Chip-Modules (MCMs). The HMC-AUH312
can be used with or without a bias-tee and requires
off-chip blocking components and bypass capacitors
for the DC supply lines. Adjustable gate voltages allow
for gain adjustment.
