AP603
High Dynamic Range 7W 28V HBT Amplifier
2110-2170 MHz Application Note: Changing Icq Biasing Configurations
The AP603 can be configured to be operated with lower bias current by varying the bias-adjust resistor – R2. The
recommended circuit configurations shown previously in this datasheet have the device operating with a 160 mA as the
quiescent current (ICQ). This biasing level represents the best tradeoff in terms of linearity and efficiency. Lowering ICQ will
improve upon the efficiency of the device, but degraded linearity. Increasing ICQ has nominal improvement upon the linearity,
but will degrade the device’s efficiency. Measured data shown in the plots below represents the AP603 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.
