ADI launches GaAs pHEMT driver amplifier

Analog Devices has introduced a medium-power, distributed driver amplifier which operates between 24GHz and 35GHz.

The HMC1131 amplifier provides 22dB of gain, +35dBm output IP3, and +24dBm of output power at 1dB gain compression.

It reduces the number of components required to achieve the desired output power and small signal gain, which lowers development costs and design time by enabling simpler transmit line-ups and higher integration, according to Analog.

Based on a GaAs pHEMT design, the HMC1131 is intended for civil and defence communications systems, including point-to-point and point-to-multi-point radios and VSat and Satcom applications.
The HMC1131 can supply +25dBm of saturated output power with 16% PAE and is housed in a compact, leadless 4x4mm ceramic surface-mount package.

The company writes:

The HMC1131 is a gallium arsenide (GaAs), pseudomorphic high electron mobility transfer (pHEMT), monolithic microwave integrated circuit (MMIC), driver amplifier that operates from 24 GHz to 35 GHz. The HMC1131 provides 22 dB of gain at the 24 GHz to 27 GHz range, 35 dBm output IP3, and 24 dBm of output power at 1 dB gain compression, while requiring 225 mA from a 5 V supply. The HMC1131 is capable of supplying 25 dBm of saturated output power and is housed in a compact, 4 mm × 4 mm ceramic leadless chip carrier (24-lead LCC). The HMC1131 is an ideal driver amplifier for a wide range of applications, including point-to-point radios, from 24 GHz to 35 GHz.
