Applications Information
Typical performance that can be expected from this circuit at 3.0 and 3.5 V V
component values can be changed to enhance the performance of a particular parameter but usually at the
expense of another. Gain can be improved by sacrificing stability (R3 and R5). Input return loss can be
sacrificed to improve noise figure. IIP3 can be improved by increasing emitter degeneration (L3) and bias
current (R2). Unused traces are available on the PCB to add emitter degeneration at leads 1 and 3 of the
device.
