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.
