Product Details

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.

Sys-Parameter Models for Keysight Genesys

Sys-Parameter models contain behavioral parameters, such as P1dB, IP3, gain, noise figure and return loss, which describe nonlinear and linear characteristics of a device.


Design Tools


ADIsimRF is an easy-to-use RF signal chain calculator. Cascaded gain, noise, distortion and power consumption can be calculated, plotted and exported for signal chains with up to 50 stages. ADIsimRF also includes an extensive data base of device models for ADI’s RF and mixed signal components.

Design Resources

ADI has always placed the highest emphasis on delivering products that meet the maximum levels of quality and reliability. We achieve this by incorporating quality and reliability checks in every scope of product and process design, and in the manufacturing process as well.  "Zero defects" for shipped products is always our goal.
