The HMC1121 is a three-stage, gallium arsenide (GaAs), pseudomorphic high electron mobility transfer (pHEMT), monolithic microwave integrated circuit (MMIC), 4 W power amplifier with an integrated temperature compensated on-chip power detector that operates between 5.5 GHz and 8.5 GHz. The HMC1121 provides 28 dB of gain, 44 dBm output IP3, and 36.5 dBm of saturated output power at 30% PAE from a 7 V power supply.
The HMC1121 exhibits excellent linearity and it is optimized for high capacity, point to point and point to multipoint radio systems. The amplifier configuration and high gain make it an excellent candidate for last stage signal amplification preceding the antenna.
Ideal for supporting higher volume applications, the HMC1121 is provided in a 40-lead LFCSP package.

Tools & Simulations
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.
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.
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.
