The latest medium-power, distributed driver amplifier is designed to lower development costs and reduce design time in applications such as civil and defense communications systems. Distributed amplifiers are circuit designs that incorporate transmission line theory into traditional amplifier design to obtain a larger gain-bandwidth product than is realisable by conventional circuits. The amplifier from Analog Devices reduces the number of components delivering high gain and output power for easy integration.
According to the press release, “The HMC1131 is a gallium arsenide (GaAs), pseudomorphic high electron mobility transfer (pHEMT), monolithic microwave integrated circuit (MMIC), driver amplifier that operates from 24GHz to 35GHz. The HMC1131 provides 22dB of gain at the 24GHz to 27GHz range, 35dBm output IP3, and 24 dBm of output power at 1dB gain compression, while requiring 225 mA from a 5V supply. The HMC1131 is capable of supplying 25 dBm of saturated output power and is housed in a compact, 4mm × 4mm 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 24GHz to 35GHz.”
The HMC1131 amplifier is priced at US$ 34.15 each per 1000 quantity, according to the company release.
