... Product Preview Dual Band EDGE Compatible PA Controller The NCS5021 circuit is dedicated to RF Power amplifier control for GSM and DCS standards. It significantly reduces the number of external passive devices while giving the RF designer the capability to perfectly tune the control loop. This device is compatible with both constant and non− ...

... Power−down Mode During the unused time slots in Time Division Multiple Access (TDMA) systems, the NCS5021 must be in low power mode by applying a zero logic level on pin ENABLE. This function saves power from battery and put PA in low power by supplying very low level to output buffer V Also when power− ...
