Product Details

The HMC-AUH249 is a GaAs MMIC HEMT Distributed Driver Amplifier die which operates between DC and 43 GHz and provides a typical 3 dB bandwidth of 35 GHz. The amplifier provides 15 dB of gain and +23 dBm of saturated output power while requiring only 200 mA from a +5V supply voltage.

The HMC-AUH249 exhibits very good gain and phase ripple beyond 25 GHz and can output greater than 8V peak-to-peak, making it ideal for for use in broadband wireless, fiber optic communication and test equipment applications. The amplifier die occupies less than 4 mm² which facilitates easy integration into Multi-Chip-Modules (MCMs). The HMC-AUH249 requires a bias-tee as well as off-chip blocking components and bypass capacitors for the DC supply lines. Vgg1 adjusts the bias current for the device while Vgg2 adjusts the output gain.

Tools & Simulations


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.
