Philips Semiconductors Preliminary specification
UHF amplifier module BGY280
FEATURES
• Dual band GSM amplifier
• 3.6 V nominal supply voltage
• 33.5 dBm output power for GSM1800
• 35.5 dBm output power for GSM900
• Easy output power control by DC voltage.
• Internal input and output matching.
APPLICATIONS
• Digital cellular radio systems with Time Division Multiple
Access (TDMA) operation (GSM systems) in two
frequency bands: 880 to 915 MHz and
1710 to 1785 MHz.
DESCRIPTION
The BGY280 is a power amplifier module in a SOT559A
leadless package with a plastic cap. The dimensions are
13.75 x 11 x 1.7 mm. The module consists of two
separated line-ups. One for GSM900 and one for
GSM1800. Internal power control, input and output
matching.
