ncs5000
Description
Integrated Rf Schottky Detector
Manufacturer
ON Semiconductor
Datasheet
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.
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.
portable applications. The TSOP–6 package is a lower profile,
footprint compatible package to the SOT23–6.

... In addition to the RF detector, a reference detector is included so the NCS5000 can be used to implement a differential detector. Since the RF and reference detectors are integrated on the same silicon, they track each other tightly over temperature, bias voltage, and process. Each detector is biased with approximately current and there is a built– ...
