AWT6172
EDGE Power Amplifiers
Application:
Dual/Tri/Quad Band Handsets, PDAs and Data Devices
Description:
This quad band power amplifier module supports dual, tri and quad band applications for both GMSK and 8-PSK modulation schemes. There are two amplifier chains, one to support GSM850/900 bands, the other for DCS/PCS bands.
The module includes an integrated power control scheme for use in the GMSK mode. This facilitates fast and easy production calibration and reduces the number of external components required to complete a power control function. The amplifier’s power control range is typically 55 dB, with the output power set by applying an analog voltage to VRAMP.
In EDGE mode, the VRAMP pin is disabled and no specific voltage is required for proper operation. Output power is controlled by varying the input power.
All of the RF ports for this device are internally matched to 50Ω.
