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, Vgg2 is provided for limited gain adjustment, while Vgg1 adjusts the bias current for the device.
