AWT6280
EDGE Power Amplifiers
Application:
Dual/Tri/Quad Band handsets, PDAs, and data devices
Description:
This power amplifier module supports dual, tri and quad band applications for GMSK and 8-PSK modulation schemes using an open loop polar architecture. There are two amplifier chains, one to support GSM850/900 bands, the other for DCS/PCS bands. Each amplification chain is optimized for excellent EDGE efficiency, power, and linearity in a Polar loop environment while maintaining high efficiency in the GSM/GPRS mode.
The module includes an internal reference voltage and integrated power control scheme for use in both GMSK and 8-PSK operation. 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. All of the RF ports for this device are DC blocked and internally matched to 50 Ω.
