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 +7.0 V while monitoring drain current. Raise VGG until drain current reaches 1300 mA. VGG should be between -1.5 and -0.6 V. Apply RF power. To improve the thermal and RF performance, ASB recommends a heat sink er 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.

- Mounting Instructions for Flange Package
4.1 Screw Mounting
4.1.1 The flange of package should be attached using screws. Torque conditions are shown in table 1. Table 1. Recommended and Maximum Torque for Screw Mounting
4.1.2 First, tighten the screws with a torque driver set to 5 N-cm
thermal resistance between the package and heat sinker. 4.2.2 After soldering, the flux residue should be removed by appropriate cleaning methods.
4.2.3 The recommended soldering conditions are as follows:
