AH312
2 Watt, High Linearity InGaP HBT Amplifier
Application Note: Reduced Bias Configurations
The AH312 can be configured to be operated with lower bias current by varying the bias-adjust resistor – R1.
The
recommended circuit configurations shown previously in this datasheet have the device operating in Class A operation.
Lowering the current has little effect on the gain, OIP3, and P1dB performance of the device, but will slightly lower the
ACLR/ACPR performance of the device as shown below. An example of the measured data below represents the AH312
measured and configured for 2.14 GHz applications. It is expected that variation of the bias current for other frequency
applications will produce similar performance results.
