Description
The QB-904 is a class AB amplifier
operating over the 2 to 6 GHz frequency
range. With a DC input voltage range of
+23 to +28 VDC, the QB-904 provides 38
dB of small signal gain and output power
of +36 dBm (typical) over the 2 to 6 GHz
frequency band.
Typical current drawn from a 24 VDC
supply at +36 dBm output power is 900
mA. The QB-904 is packaged in a
hermetically sealed housing and is
configured with field replaceable SMA
connectors as shown, or 0.015” gold-
plated pins for a surface-mount launch.
An optional heat sink is available when
using the unit in a bench testing
environment.
