General Description
Functional Diagram
The HMC-AUH232 is a GaAs MMIC HEMT Distributed
Driver Amplifier die which operates between DC and
43 GHz and provides a typical 3 dB bandwidth of
46 GHz. The amplifier provides 12 dB of small
signal gain while requiring only 180 mA from a +5V
supply. The HMC-AUH232 exhibits very good gain
and phase ripple to 40 GHz, and can output up to
8V peak-to-peak with low jitter, making it ideal for use
in broadband wireless, fiber optic communication and
test equipment applications. The amplifier die occupies
less than 3.6 mmꢀ which facilitates easy integration
into Multi-Chip-Modules (MCMs). The HMC-AUH232
requires external bias-tee as well as off-chip blocking
components and bypass capacitors for the DC supply
lines. A gate voltage adjust, Vgg2 is provided for
limited gain adjustment, while Vgg1 adjusts the bias
current for the device.
