3.1 Application Circuit
ASX1037HG
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
ï¬ Make sure no RF power is applied to the device before continuing.
ï¬ Pinch off device by setting VGG to -1.5 V.
ï¬ Raise VDD to +7.0 V while monitoring drain current.
ï¬ Raise VGG until drain current reaches 1300 mA. VGG should be between -1.5 and -0.6 V.
ï¬ Apply RF power.
ï¬ To improve the thermal and RF performance, ASB recommends a heat sinker attached to the
bottom of the package with an Indium alloy preform.
