Description
The QBS-562 is class AB amplifier with a narrow band fre-
quency range of 876 to 960 MHz. Operating over a DC
input voltage of +28 Vdc, the QBS-562 provides 34 dB
small signal gain. Output power of +44 dBm is provided
over the 876 to 960 MHz frequency band. Typical current
drawn from a +28 V supply at +44 dBm output power is
3000 mA.
