Preliminary specification

dual band UHF amplifier module for GSM900 and GSM1800

BGY282

FEATURES

• Dual band GSM amplifier

• 3.5 V nominal supply voltage

• 33 dBm output power for GSM1800

• 35 dBm output power for GSM900

• Easy output power control by DC voltage

• Internal input and output matching

• Easy band selection by DC voltage

• Suited for GPRS class 12 (duty cycle 4 : 8).

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 BGY282 is a power amplifier module in a SOT632A

surface mounted ceramic package with a plastic cap.

The module consists of two separated line-ups, one for

GSM900 and one for GSM1800 with internal power

control, input and output matching.
