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 3.1 amps with a saturated gain of 37 dB, and a typical
output power of 32 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.
