NOTE: Adequate heat relief must be used when operating this amplifier. Customer must use either a Spectrum Microwave heat sink or mount onto either a copper bus bar or thermal plate to remove excess heat. Description The QB-910 is a class AB amplifier operating over the 2 to 6 GHz frequency range. Operating over a DC input voltage range of +23 to +28 Vdc, the QB-910 provides 27 dB small signal gain. Output power of +27 dBm (typical) is provided over the 2 to 6 GHz frequency band. Typical current drawn from a 24 V supply at +27 dBm output power is 250 mA. The QB-910 is packaged in a hermetically sealed housing and is available with field replaceable SMA connectors, or 0.015” gold-plated pins for through-board mount. An optional heat sink is available when using the unit in a bench testing environment.
