QBS-611 Datasheet, PDF (1/2 Pages) API Delevan – RF Adjustable AGC/Limiting Line Amplifier L-Band 1.0 – 2.0 GHz

Model # QBS-611
RF Adjustable AGC/Limiting Line Amplifier
L-Band 1.0 – 2.0 GHz
• Adjustable Small-Signal Gain, AGC Output Threshold, Minimum Gain, and
Maximum Output Power
• Uses GaAs MESFET and E-pHEMT Technologies
• Variable AGC and Limiting Module
• Class A Output Stage
• Microprocessor Based Control Loop
API Technologies’ Model QBS-611 is an automatic gain control/limiting line amplifier module covering 1-2 GHz. This
design provides variable small-signal gain, AGC output power threshold, minimum gain, and maximum output power
settings. The QBS-611 allows for adjustment, via mechanical set screw, of four key operating parameters to allow for
ease of integration and system alignment.
