BIASING GUIDELINES
Active bias circuits provide good performance stabilization over variations of operating
temperature, but require a larger number of components compared to self-bias or dual-biased.
Such circuits should include provisions to ensure that Gate bias is applied before Drain bias,
otherwise the pHEMT may be induced to self-oscillate. Contact your Sales Representative for
additional information.
Dual-bias circuits are relatively simple to implement, but will require a regulated negative
voltage supply for depletion-mode devices such as the FPD200P70.
For standard Class A operation, a 50% of I
DSS
bias point is recommended. A small amount of
RF gain expansion prior to the onset of compression is normal for this operating point. Note that
pHEMTs, since they are “quasi- E/D mode” devices, exhibit Class AB traits when operated at
50% of I
DSS
. To achieve a larger separation between P
1dB
and IP3, an operating point in the 25%
to 33% of I
DSS
range is suggested. Such Class AB operation will not degrade the IP3
performance.
