Abstract
The present invention relates to a circuitry for detecting the power of a RF signal ( ) comprising a FET transistor ( ) connected in parallel to two inputs ( ′) for supplying the RF signal and two outputs ( ′) for detecting the power of the RF signal ( ). The circuitry has a resistor ( ) having a resistance larger than the drain-source resistance of the FET transistor ( ). This resistor ( ) is connected between one of the outputs and the source ( ) of the FET transistor ( . Further a capacitor ( ) is connected between one of the input and the source of the FET transistor. The gate ( ) of the FET transistor is connected to ground.
