InGaP HBT MMIC technology to provide reliability,

temperature stability, and ruggedness. This penta-

band module consists of three ampliﬁer chains; one

to support GSM/GPRS/EGPRS in cellular bands, one

to support GSM/GPRS/EGPRS in DCS/PCS bands,

and one to support WCDMA in the IMT band. In ad-

dition, the AWT6223R module includes an internal

reference voltage and integrated power control with

temperature compensation for use in GMSK and

8-PSK modes of operation. These features facilitate

fast and easy production calibration, minimize per-

formance variation over temperature, and reduce the

number of external components required.

Low Leakage Current in Shutdown Mode: <1 A

Internal Voltage Regulator Eliminates the Need for

External Reference Voltage

The WCDMA PA incorporates ANADIGICS’ HELP2^TM

technology. Through selectable bias modes, the

AWT6223R achieves optimal efficiency across

different output power levels, specifically at low

and mid-range power levels where the PA typically

operates, thereby dramatically increasing handset

talk-time and standby-time. Its built-in voltage regulator

eliminates the need for an external reference voltage

and switch components, reducing PCB area and BOM

costs. All of the RF ports for this device are internally

matched to 50 . The RF inputs GSM_IN and DCS/

PCS_IN both have shunt resistors to ground to main-

tain a good input VSWR as the V^RAMPpower control

voltage is varied. Internal DC blocks are provided at

the RF outputs.
