... DQ Because the FP31QF is a discrete device, users can choose their own bias configuration. Performance may vary from the data shown depending on the biasing conditions. To achieve a minimum 1 million hours MTTF rating, the biasing condition should maintain a junction temperature below 160° C over all operating temperatures. This can be approximated by (drain voltage) x (drain current) x 17.5° ...

... The active-bias circuit, shown on the right, uses dual PNP transistors to provide a constant drain current into the FP31QF, while also eliminating the effects of pinchoff variation. This configuration is best suited for applications where the intended output power level of the amplifier is backed off at least 6 dB away from its compression point ...
