Model Number: QBS-609 1 kW Solid State Pulsed Power Amplifier X-Band Microwave Power Module using GaN Technology Features • 1 kW Peak Output Power • Typical frequency range of 9.0 to 9.8 GHz • Efficiencies as high as 20% • Up to 100 µsec pulse width, 10% duty cycle • Targeted for TWT Amplifier Replacement • Military and Commercial Radar Applications API Technologies’ Model QBS-609 is a 1kW peak output power, solid state amplifier designed as a replacement for traveling wave tube modules over the 9.2 to 9.8 GHz frequency range. Operating from a +28VDC isolated supply, the QBS-609 has 60dB minimum gain with performance up to 100 µsec pulse widths at 10% duty cycle. Amplitude droop across a pulse of this duration is less than 1.3 dB. Phase distortion is minimized by gating the discrete power supply OFF during pulsed RF operation. Additional advantages of the GaN power module over a traveling wave tube counterpart include increased MTBF, soft fail vs. catastrophic fail, and lower long term replacement/repair cost. An integrated controller provides customer interface and fault monitoring options.
