Ruggedness APPLICATION INFORMATION The module will withstand a load mismatch VSWR of 50:1 (all phases) for short period overload conditions, with PD, VS1 and VS2 at maximum values providing the combination does not result in the matched RF output power rating being exceeded. Supply An electrolytic capacitor of 10 µF, 25 V, in parallel with a polyester capacitor of 100 nF to earth, is recommended as a decoupling arrangement for each power supply pin. Power rating MOUNTING In general it is recommended that the output power from the module under nominal conditions should not exceed 23 W in order to provide an adequate safety margin under fault conditions. To ensure good thermal transfer the module should be mounted on a heatsink with a flat surface with heat-conducting compound applied between module and heatsink. If an isolation washer is used, heatsink compound should be applied to both sides of the washer. Burrs and thickening of the holes in the heatsink should be removed and 3 mm bolts tightened to a maximum torque of 0.5 Nm. The leads of the devices may be soldered directly into a circuit using a soldering iron with a maximum temperature of 245 °C for not more than 10 seconds at a distance of at least 1 mm from the plastic. 1996 Jun 06 Output power control The module is not designed to be operated over a large range of output power levels. The purpose of the output power control is to set the nominal output power level. The preferred method of output power control is by varying the drive power between 50 and 200 mW. The next option is by varying VS1 between 6 and 12.5 V. 5 Philips Semiconductors Product specification VHF power amplifier modules BGY32; BGY33; BGY35; BGY36 PACKAGE OUTLINE 52.5 50.0 44.9 17.0 14.4 8.1 9.3 6.8 3.7 4.2 0.25 7.65 max 12 34 5 67 19.7 3.3 61.0 A 8.5 17.0 3.5 0.5 0.2 M A 52.5 MBC876 67.5 Dimensions in mm.
