3. Application: 13.5 – 16.0 GHz
3.1 Application Circuit
ASX1536
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.
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.
