3. Application: 13.75 ~ 14.50 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 -3.5 V.



Raise VDD to +28 V while monitoring drain current.



Raise VGG until drain current reaches 350 mA. VGG should be between -3.5 and -2.5 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.
