Broadband Wireless has developed a linearized 200 W peak power amplifier operating in the 1805 to 1880 MHz band. Linearized output power is 50 W (80 W maximum) with ACPR (5 MHz W-CDMA at 7.5 dB PAR) of <–45 dBc at 5 MHz and < 50 dBc at 10 MHz. With a 10 MHz LTE waveform at 50 W, the ACP is <–45 dBc at 10 MHz offset. The RF gain is 45±0.5 dBm (adjustable) with ±0.5 dB gain over the frequency and temperature range. The noise figure is 12 dB.
The DC current at 28 V is 5.5 A maximum at 50 W average RF power with an operating base plate temperature from -30° to + 80°C. It is a packaged in a 8" x 4" package with SMA female connectors for RF, nine pin D-Sub female and two pin Molex 0428202222 for DC power. Harmonic level is -45 dBc with input/output return loss of 18 dB min. Broadband Wireless has produced this PA in bands from 700 to 2700 MHz.
Broadband Wireless supplies RF and microwave amplifiers to commercial and government customers in the telecommunications, defense and aerospace industries. They specialize in customized linear high efficiency RF power amplifiers for the communications industry.
