• 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.
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.
See the simplified internal circuit on page 4.
The power control circuit ensures a stable power output set by the level of VDAC and stabilised to compensate variations
of supply voltage, input power and temperature, with a control range fully compliant with ETSI time mask and power
spectrum requirements
