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 R3 is dependent upon the supply
voltage and allows for bias stability over temperature.
WJ recommends a minimum supply bias of +9 V. A
