Power amps for E-band radio cover 71-76GHz, 81-86GHz range

GigOptix Inc. has released engineering samples of its new generation of power amplifiers covering the 71-76GHz and 81-86GHz frequencies for high capacity E-band radios. The GaAs pHEMT MMIC power amplifiers EXP7602 and EXP7603 provide gain of 16dB and 20dB, respectively, across the 71-76GHz band.

The EXP7602 delivers a P1dB above 23dBm with saturated output power above 25dBm. EXP7603 delivers a P1dB above 25dBm with saturated output power above 26dBm. The GaAs pHEMT MMIC power amplifier EXP8602 provides gain of 18dB across the 81-86GHz band and delivers a P1dB above 20dBm with saturated output power above 23dBm. All three power amplifiers feature on chip temperature compensated output power detector to simplify system assembly and increase power efficiency. These powerful amplifiers feature RF inputs and outputs that are internally matched to 50? and require no external matching components. The devices are very power efficient and typically dissipate 2.2W during operation, detailed the company.

"These new powerful amplifiers represent a major improvement for our customers," said Andrea Betti-Berutto, CTO of GigOptix. "The devices feature high gain and high output power levels with excellent return losses. The availability of on chip output power detector will enable customers to meet the challenging E-band radio specification whilst simplifying their integration. The new devices enable E-band radios to transmit more data, more efficiently over a longer distance and at a more competitive price to what is currently available in the market. We expect our new power amplifier solutions to be a significant contributor to our future growth in the E-band market."
