Módulo AD8361 100MHz - 2,5 GHz RF TruPwr Módulo detector de potencia verdadera Detector de potencia momentáneo Módulo detector de amplitud AM

First, product application:

The AD8361 is a mean response power detector for high frequency receiver and

transmitter signal chains up to 2.5 GHz. The device is very simple to use, requiring

only a single power supply from 2.7 V to 5.5 V, a power decoupling capacitor, and

an input coupling capacitor to operate in most applications. The output is linearly

responsive to DC voltage and the conversion gain is 7.5V /V RMS value. An

external filter capacitor can be added to increase the average time constant.

The AD8361 is primarily used for true power measurement with simple and

composite waveforms, and is particularly suitable for measuring high crest factor

(peak-rMS ratio) signals such as CDMA and W-CDMA. The AD8361 operates in

three modes to support a variety of analog-to-digital converter requirements:

1, the reference voltage source grounding mode, the source is zero.

2, the internal reference voltage source mode, the output can be biased to 350

mV above the ground level.

3, provide reference voltage source mode, the output can be biased to VS/7.5.
