QBS-559 Datasheet, PDF (1/2 Pages) API Technologies Corp – 50 Watt Power Amplifier

50 Watt Power Amplifier
20-800 MHz
Model QBS-559
FEATURES
• High Output Power to 50 Watts
• Class AB Design
• Ultra HIgh Efficiency S.M.A.R.T. Design
• Built-in Fault Monitoring
• Harmonic Filters
• Thermal Temperature Compensating Circuitry
The QBS-559 is class AB amplifier operating over 20 to 800 MHz frequency range. Operating over a DC input voltage
of +28 VDC, the QBS-559 provides 45 dB of linear gain and 42 dB saturated power gain. Output power of 50 watts is
provided over the 20 to 800 MHz frequency band. The amplifier has an integrated DC to DC converter providing a 21 to
30 VDC operating voltage range drawing 5.0 amps of current. This rugged S.M.A.R.T. design automatically adjusts bias
levels for peak efficiency and will not be damaged even with a 10:1 load mismatch.
