1. The proper values for the components are dependent upon the intended frequency of operation.
2. The component values in the table below are contained on the evaluation board to achieve optimal broadband
performance.
3. R2 and R3 are shown in the circuit diagram to avoid potential instabilities. The configuration shown above assures
of unconditional stability with the use of the device. It is expected that linearity parameters (OIP3 and P1dB) to
degrade about only 0.5 dB, while overall gain will be about 2 dB less than the performance shown in page 1 and 2 of
this datasheet. Input and output return loss is expected to improve with the use of the I/O series resistances at 2 GHz.

The proper value for R1 is dependent upon the supply
voltage and allows for bias stability over temperature.
WJ recommends a minimum supply bias of +9 V.
