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.

Notes:
1. 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.
