HF amplifier modules
FEATURES * Single 6 V nominal supply voltage * 3 W output power * Easy control of output power by DC voltage * Silicon bipolar technology * Standby current less than 100 A. APPLICATIONS * Portable communication equipment operating in the 400 to 440 MHz and 430 to 488 MHz frequency ranges respectively. DESCRIPTION The BGY148A and BGY148B are three-stage UHF amplifier modules in a SOT421A package. 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 with an RF drive power of 10 mW. QUICK REFERENCE DATA RF performance at Tmb = 25 C.

SOLDERING The indicated temperatures are those at the solder interfaces. Advised solder types are types with a liquidus less than or equal to 210 C. Solder dots or solder prints must be large enough to wet the contact areas. 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. 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. The maximum ramp-up is 10 C per second. The maximum cool-down is 5 C per second. 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.

BGY148A; BGY148B
This data sheet contains target or goal specifications for product development. This data sheet contains preliminary data; supplementary data may be published later. This data sheet contains final product specifications.
Limiting values given are in accordance with the Absolute Maximum Rating System (IEC 134). Stress above one or more of the limiting values may cause permanent damage to the device. These are stress ratings only and operation of the device at these or at any other conditions above those given in the Characteristics sections of the specification is not implied. Exposure to limiting values for extended periods may affect device reliability. Application information Where application information is given, it is advisory and does not form part of the specification. LIFE SUPPORT APPLICATIONS These products are not designed for use in life support appliances, devices, or systems where malfunction of these products can reasonably be expected to result in personal injury. Philips customers using or selling these products for use in such applications do so at their own risk and agree to fully indemnify Philips for any damages resulting from such improper use or sale.
