Each module consists of three NPN silicon planar transistor dies mounted together with matching and bias circuit components on a metallized ceramic substrate. The modules produce an output power of 3 W into a load of 50 Ω with an RF drive power of 10 mW. 1 2 3 4 Top view MSA483 Fig.1 Simplified outline (SOT421A).

MGM159 300 handbook, halfpage Advised solder types are types with a liquidus less than or equal to 210 °C. T (°C) Solder dots or solder prints must be large enough to wet the contact areas. 200 Soldering can be carried out using a conveyor oven, a hot air oven, an infrared oven or a combination of these ovens. A double reflow process is permitted. 100 Hand soldering must be avoided because the soldering iron tip can exceed the maximum permitted temperature of 250 °C and damage the module. The maximum allowed temperature is 250 °C for 5 seconds. 0 0 1 2 3 4 t (min) 5 The maximum ramp-up is 10 °C per second. The maximum cool-down is 5 °C per second. Fig.17 Recommended reflow temperature profile. Cleaning The following fluids may be used for cleaning: • Alcohol • Bio-Act (Terpene Hydrocarbon) • Acetone. Ultrasonic cleaning should not be used since this can cause serious damage to the product. 1998 May 13 8 Philips Semiconductors Product specification HF amplifier modules BGY148A; BGY148B 22.6 handbook, full pagewidth DETAIL 2 0.4 0.8 1.7 2 1.5 8.45 1 2.9 2.7 0.6 2.7 1.1 0.1 2.6 2.4 0.1 7.48 DETAIL 15.1 0.5 0.7 20.18 footprint metallization solder area. 21.8 handbook, full pagewidth 2 0.8 2 2 7.05 1.7 1.8 2 7.08 14.7 MGK392 19.78 solder area.
