Typical Applications

This HMC-AUH232 is ideal for:

• 40 Gb/s Lithium Niobate/ Mach Zender

Fiber Optic Modulators

• Broadband Gain Block for Test & Measurement

Equipment

• Broadband Gain Block for RF Applications

• Military & Space

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 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, Vgg2 is provided for

limited gain adjustment, while Vgg1 adjusts the bias

current for the device.
