Part Number: QBS-560 Broadband 25 Watt GaN Power Amplifier 700 to 2500 MHz high power, class AB design utilizing GaN technology Features • 43 Watts Typical Saturated Output Power • Rugged GaN Technology o Fault Monitoring • Typical Efficiency of 39% o Temperature Compensation • Adaptive Biasing to Promote Efficiency o Sequencing • Optional Forward/Reverse Power Detection o Interface Options • Blanking Feature Available • Microprocessor Based Control API Technologies’ Model QBS-560 is a high power, class AB solid state amplifier which utilizes the latest GaN technology to offer broadband performance from 700 to 2500 MHz. The RFPA has an integrated, high efficiency DC to DC converter to promote operation over a wide DC input voltage range of +25 to +32 VDC; drawing 4.0 amps with a saturated gain of 44 dB, and a typical output power of 43 watts. The microprocessor based design incorporates an adaptive biasing algorithm to optimize efficiency and output power across the frequency band under varying load conditions. This rugged, high reliability GaN based amplifier is capable of performing in adverse commercial and military environments with EMI and moisture sealing, and will not be damaged operating into a 10:1 load mismatch at full rated power. Optional RF blanking controlled through an LVDS signal, and forward/reverse power detection are available upon request.
