The ANADIGICS WEDGE module provides the power needed for advanced 3G handsets, smartphones, and data devices. The WEDGE module supports GSM type dual, tri, and quad band applications for GMSK and 8-PSK modulation schemes using a polar architecture, as well as WCDMA in the IMT band. There are three separate amplifier chains, one to support GSM/EDGE in DCS/PCS bands, and one to support WCDMA in the IMT band. The WEDGE module includes an internal reference voltage and integrated power control scheme for use in GMSK and 8-PSK operation, which facilitates fast and easy production calibration and reduces the number of external components required.

The WEDGE module is manufactured using ANADIGICS' advanced InGaP HBT MMIC technology to provide reliability, temperature stability, and ruggedness. The WCDMA PA has selectable bias modes to optimize efficiency for different output power levels, and a shutdown mode with low leakage current, increase handset talk and standby time. All of the RF ports for this device are internally matched to 50. Internal DC blocks are provided at the RF inputs and outputs.
