Abstract:
1. A narrow band receiver or transceiver for processing of electrical signals, comprising: at least one amplifier for amplifying received signals or signals to be transmitted, a voltage controlled oscillator, and a tuning assembly or module comprising at least one control loop for tuning the voltage controlled oscillator, wherein at least a gain control of the amplifier is coupled to the at least one control loop, which is an amplitude locked loop including the voltage controlled oscillator, for simultaneously tuning the output amplitude of the voltage controlled oscillator and the gain of the amplifier with a compensation of the effect of variation on the gain of the amplifier, which includes an LC tank circuit, by using an information in another LC tank circuit of the voltage controlled oscillator for tuning of the output amplitude of the voltage controlled oscillator in the control loop.
