Product Details

The HMC634 is a GaAs MMIC PHEMT Driver Amplifier die which operates between 5 and 20 GHz. The amplifier provides up to 22 dB of gain, +31 dBm Output IP3, and up to +23 dBm of output power at 1 dB gain compression, while requiring 180 mA from a +5V supply. The HMC634 is an ideal driver amplifier for microwave radio applications from 5 to 20 GHz, and may be biased at +5V, 130 mA to provide 2 dB lower gain with improved PAE. The HMC634 amplifier I/O’s are DC blocked and internally matched to 50 Ohms facilitating easy integration into Multi-Chip-Modules (MCMs). All data is taken with die connected at input and output RF ports via one 1 mil wedge bond with minimal length of 0.31 mm (12 mils).

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.
