AP561
0.7-2.9 GHz 8W Power Amplifier
2.5 – 2.7 GHz Application Note: Changing Icq Biasing Configurations
The AP561 can be configured to operate with lower bias current by varying the bias-adjust resistor R2. (Table 1) The
recommended circuit configurations shown previously in this datasheet have the device operating with a 300 mA as the
quiescent current (ICQ). This biasing level represents a tradeoff in terms of EVM and efficiency. Lowering ICQ will improve
upon the efficiency of the device, but degrade the EVM performance. Measured data shown in the plots below represents the
AP561-PCB2500 measured and configured for 2.6GHz applications. It is expected that variation of the bias current for other
frequency applications will produce similar performance results.
