2.3-2.7 GHz InGaP HBT 8W Linear Power Amplifier CHV2720-QJ February 2008 - Rev 08-Feb-08 Features P1dB, 8W Power Gain, 12 dB Efficiency, 25% @ 1W Positive Voltage Supply, +5V to +12V Integrated Active Bias Circuit Control Voltage Allows Different Current Settings Input Fully Matched Internally Output Pre-Matched Internally Thermally Efficient for Higher MTTF RoHS Compliant 6X6mm QFN Ideal for WiMAX and WiBRO Applications (802.16) General Description The CHV2720-QJ is a high linearity single stage class AB Heterojunction Bipolar Transistor (HBT) power amplifier capable of 12 dB of gain, 8 Watt of power at 1 dB compression and is housed in a 6X6mm QFN package. The CHV2720-QJ provides less than 2.5% EVM at 31dBm output power with 802.16 OFDM signal and peak to average power ratio of 9 dB. The input of the device is fully matched and the output is internally pre matched to 6 ohm facilitating a simplified output matching approach. This product operates off a single supply voltage between 5V and 12V and includes an internal bias circuitry to enable exact setting of quiescent current using an external control voltage. The device is ideal as a final or driver stage for WiMAX equipment in the 2.3 -2.7 GHz bands.

Vcc should be applied first and then Vcontrol. Quiescent current (Icq) can be varied by adjusting Vcontrol in order to obtain the optimum performance desired. RF power is applied after both Vcc and Vcontrol are present. When turning off the device Vcontrol is switched off first and then Vcc. Vcontrol can be used to turn off the current.
