Product Description

Product Details
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.
**Applications**
Point to point radios
Point to multipoint radios
Very small aperture terminals (VSATs) and satellite communications (SATCOMs)
Military electronic warfare (EW) and electronic counter measures (ECM)
### Features and Benefits
