AH314
2.3-2.9 GHz 2W 5V Linear Driver Amplifier
2.3 – 2.7 GHz Applications Note: Changing Icq Biasing Configurations at +5V
The AH314 can be configured to operate with lower bias current by varying the bias-adjust resistors R1 & R2. R1 sets the
quiescent current in the output stage, while R2 sets the quiescent current in the input stage. The recommended circuit
configurations shown previously in this datasheet have the device operating with a 600 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. Raising ICQ will improve the EVM performance, but degrade the efficiency of the
device. Measured data shown in the plots below represents the AH314 measured and configured for 2.6 GHz applications. It
is expected that variation of the bias current for other frequency applications will produce similar performance results.
