APPLICATION INFORMATION
The NCS5000 is an integrated RF schottky detector
designed for use in level detector and power amplifier
control circuits. The device is optimized for large signal
applications (Pin
–20 dBm) such as those found in GSM
handsets and data modems. This device has been designed
for applications that require operation from a single Li–Ion
or multi– Ni–MH battery pack. The operating range is
2.7–5.5 V so the device can be powered directly from the
battery or a low drop out regulator. To support power
sequencing, an Enable circuitry is included which allows the
device to be placed into a very low power state (
when not in use.
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 45 A of current and
there is a built–in offset of 10 mV (nom) between the RF and
the Reference Detector.
