– 14.5 GHz

3.1 Application Circuit

3.2 Biasing Procedure



Make sure no RF power is applied to the device before continuing.



Pinch off device by setting VGG to -1.5 V.



Raise VDD to +7 V while monitoring drain current.



Raise VGG until drain current reaches 1.3 A. VGG should be between -1.5 and -0.5 V.



Apply RF power.



To improve the thermal and RF performance, ASB recommends a heat sinker attached to the

bottom of the package with an Indium alloy preform.

Note 1: The capacitors are recommended on the bias supply line, close to the package, in order to

prevent video oscillations which could damage the module.
