Caution! ESD sensitive device.
Exceeding any one or a combination of the Absolute Maximum Rating conditions may
cause permanent damage to the device. Extended application of Absolute Maximum
Rating conditions to the device may reduce device reliability. Specified typical perfor-
mance or functional operation of the device under Absolute Maximum Rating condi-
tions is not implied.

Users should avoid exceeding 80% of 2 or more Limits simultaneously.
6
Thermal Resistivity: The nominal value of 25°C/W is measured with the package
mounted on a large heatsink with thermal compound to ensure adequate
(unsoldered) contact. The package temperature is referred to the source leads.
7
Maximum RF input limit must be further limited if input VSWR>2.5:1.
8
For optimum heatsinking, metal-filled through (source) via holes should be used
directly below the central metallized ground pad on the bottom of the package.

T
Active bias circuits provide good performance stabilization over variations of operating temperature, but require a larger num-
ber 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 addi-
tional information.
Dual-bias circuits are relatively simple to implement, but will require a regulated negative voltage supply for depletion-mode
devices such as the FPD1000AS.
The recommended 200mA bias point is nominally a Class AB mode. A small amount of RF gain expansion prior to the onset of
compression is normal for this operating point.
