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 50.
