General Description  
Absolute Maximum Ratings  
The CHV2721-QJ is a high linearity single stage class AB  
Heterojunction Bipolar Transistor (HBT) power amplifier  
capable of 11 dB of gain, 8 Watt of power at 1 dB  
Voltage Supply (Vcc)  
Current (Icc)  
4.5 (min) / 12 V (max)

compression and is housed in a 6X6mm QFN package. The  
CHV2721-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 3.3 -3.6 GHz bands.
