The QB-904 is a class AB amplifier operating over the 2 to 6 GHz frequency range utilizing the latest in GaN die technology. With a wide DC input voltage range of +23 to +28 VDC, the QB-904 provides 38 dB of small signal gain and a saturated output power of +36 dBm, minimum.
Typical current draw from a nominal +24 VDC supply at rated output power is <1200 mA. The QB-904 is packaged in a hermetically sealed, copper nickel housing configured with either 0.015” gold-plated pins for a direct launch to a printed circuit board, or optional field replaceable SMA connectors as shown for modular integration. A black anodized heat sink, designed to fit the package and accommodate port connections, is available when using the unit in a standalone or bench testing environment.
