Model: QBS-610 RF Adjustable AGC/Limiting Line Amplifier L-Band 1.0 - 2.0 GHz Features • 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-610 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-610 allows for adjustment, via mechanical set screw, of four key operating parameters to allow for ease of integration and system alignment.

Specification ratings are based on measurements in a 50 ohm system. Damage may occur at input levels above +8dBm. Adjustable via external set screw. Valid for output power levels below AGC threshold. Power level measured at RF output connector. Measured with input power level of -20 dBm. Measured across entire frequency band under all gain/output power conditions. Measured across any 120MHz band under all gain/output power conditions. All set screws adjusted to nominal values with power levels up to -13dBm. Alternate DC power supply voltages available as a custom solution. Normal operating state is a low impedance contact (collector) capable of sinking up to 10 mA.
