Functional Diagram
General Description
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
voltage. 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 for
use in broadband wireless, fiber optic communication
and test equipment applications. The amplifier die
occupies less than 3.6 mm2 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, Vg2
is provided for limited gain adjustment, while Vg1a
adjusts the bias current for the device.
