Application: 13.5 – 14.5 GHz 3.1 Application Circuit 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 4/13 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. ASB Inc.

Torque conditions are shown in table 1. Table 1. Recommended and Maximum Torque for Screw Mounting Package Recommended Screw Recommended Torque Maximum Torque Flange M2.0 10 N-cm (0.9 lb-in) 15 N-cm (1.3 lb-in) 4.1.2 First, tighten the screws with a torque driver set to 5 N-cm 4.1.3 The surface finish of the heat sinker should be better than 0.8 µm and the surface flatness must be better than 10 µm. 4.1.4 Silicon based heat sink compounds should not be used for the thermal conductive grease. It causes the poor grounding of the source flange, contamination, and long term degradation of thermal resistance between the package and heat sinker. 4.2. Solder Mounting 4.2.1 Recommended solder is lead-free solder (Sn-3.0Ag-0.5Cu) or equivalent. 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: Partial heating method: Soldering iron, spot laser/air Product terminal temperature: 260°C, max. 10 sec/terminal or 400°C, max. 3 sec/terminal 12/13 ASB Inc.
