DESCRIPTION

The BGY284 is a power amplifier module in a SOT775 surface mounted package with a plastic cap. The module consists of two separated line-ups, one for low band (LB,GSM850/EGSM900) and one for high band (HB, DCS1800/PCS1900) with internal power detection function, power control loop, input and output matching.

FEATURES

• Quad band GSM amplifier

• Very small size (8 x 8 mm).

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

• Integrated power control loop

• 3.5 V nominal supply voltage

• 35 dBm controlled output power for GSM850/EGSM900

• 32.5 dBm controlled output power for DCS1800/PCS1900

• Easy on/off and band select by digital control voltage

• Internal input and output matching

• Specification based on 3GPP TS 45.005.

APPLICATIONS

• Digital cellular radio systems with Time Division Multiple Access (TDMA) operation (GSM systems) in four frequency bands: 824 to 849 MHz, 880 to 915 MHz, 1710 to 1785 MHz and 1850 to 1910 MHz.
