AH215 / ECP100G
1 Watt, High Gain HBT Amplifier
Product Information
Application Note: Reduced Bias Configurations
The AH215 / ECP100 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 AH215 /
ECP100 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.
