NCS5000
Integrated RF Schottky
Detector
The NCS5000 is an integrated schottky detector intended for use as
a level detector in RF measurement/power control applications such as
those found in GSM handsets. The detector converts the peak RF
voltage applied to a DC level. The circuit consists of an RF schottky
detector, a reference schottky diode, as well as biasing and control
circuitry. There is an enable input that allows the part to be placed in a
low power state when not in use.
The detector is designed for operation up to 2.0 GHz and can operate
with input power levels up to +25 dBm. There is a fixed offset of
10 mV (nominal) between the Reference Detector and the RF Detector
under no applied RF. The two detectors are monolithically integrated
so that they closely track over temperature, voltage and process.
The NCS5000 is housed in a very small TSOP–6 package ideal for
portable applications. The TSOP–6 package is a lower profile,
footprint compatible package to the SOT23–6.
