Product Details

The HMC1144 is a gallium arsenide (GaAs), pseudomorphic high electron mobility transfer (pHEMT), monolithic microwave integrated circuit (MMIC), distributed power amplifier that operates from 35 GHz to 70 GHz. In the lower band of 35 GHz to 50 GHz, the HMC1144 provides 19 dB (typical) of gain, 28 dBm output IP3, and 19 dBm and 19.5 dBm, respectively, of output P1dB gain compression. In the upper band of 50 GHz to 70 GHz, the HMC1144 provides 19 dB (typical) of gain, 32 dBm output IP3, and 21 dBm of output power at 1 dB gain compression. The HMC1144 requires 320 mA from a 4 V supply. The HMC1144 amplifier inputs/outputs are internally matched to 50 Ω, facilitating integration into multichip modules (MCMs). All data is taken with the chip connected via two 0.025 mm (1 mil) wire bonds of 0.076 mm (3 mil) minimal length.

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.
