The AP602 can be configured to operate 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 80 mA as the quiescent current (I
This biasing level represents the best tradeoff in terms of linearity and efficiency. Lowering I
efficiency of the device, but degraded linearity. Increasing I
the device’s efficiency. Measured data shown in the plots below represents the AP602 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.
