24-35 GHz communications system, medium-power driver amplifier

September 03, 2015 // By Graham Prophet
Analog Devices has added, from the product lines acquired with Hittite Microwave, a medium-power, distributed driver amplifier which operates between 24 and 35 GHz and delivers high gain and output power; the HMC1131 amplifier provides 22 dB of gain, +35 dBm output IP3, and +24 dBm of output power at 1-dB gain compression.

The amplifier reduces the number of components required to achieve the desired output power and small signal gain, enabling simpler transmit line-ups and higher integration. Based on a GaAs (gallium-arsenide) pHEMT (pseudomorphic high-electron mobility transistor) 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 is capable of supplying +25 dBm of saturated output power with 16% PAE and is housed in a leadless 4 x 4 mm ceramic surface-mount package. It uses 225 mA from a 5V supply, and is priced at $34.15 (1000).
