Part Number: QB-865 2 Watt Broadband Driver Amplifier 800 to 2200 MHz Class A Linear Design Features • • • • High Output Power: +33 dBm Typical Flat Gain Balanced Configuration Excellent Intermodulation Performance 3rd Order Intercept: +48 dBm Typical 2nd Order Intercept: +65 dBm Typical API Technologies’ model QB-865 is a single stage, high dynamic range driver amplifier with extended performance from 800 to 2200 MHz to cover major telecommunication bands. Using a high reliability GaAs MESFET technology in a balanced configuration, the module is able to achieve 2W of output power at 1dB compression with exceptional linearity, gain flatness, and VSWR at the In/Out ports across the entire frequency range. The discrete design is supplied in an aluminum package with SMA-F connectors for the RF ports and a 9 pin D-Sub for DC power to facilitate system integration. Operating from a nominal +12V power supply, the QB-865 draws approximately 650 mA with a small signal gain of 14 dB and a typical noise figure of 5.0 dB. Optional services include over temperature testing, environmental screening, and(or) alternate package configurations.

Specification ratings are based on measurements in a 50 ohm system with a DC supply voltage tolerance of ± 2%. 2. With RF output port terminated into 50 ohms (Load VSWR ≤ 2.0 :1) 3. Maximum Operating Case Temperature is defined as the baseplate temperature which, if exceeded for extended periods, could result in premature unit failure. This data is provided for user reliability information. This may or may not represent the maximum temperature for electrical parameter specifications. Rev Date: 5/12/2014 © API Technologies Corp.
