    摘要： A receiver apparatus for tracking and rejecting a Transmit (Tx) signal in a wireless communication system and an operation method thereof are provided. The receiver apparatus includes a controller for receiving channel frequency information of the Tx signal and for controlling an operation for tracking and rejecting a frequency of the Tx signal; a phase locked loop for generating an oscillation frequency by generating a control voltage according to the channel frequency information of the Tx signal under the control of the controller and for filtering a signal corresponding to the oscillation frequency among signals input to a low noise amplifier; and the low noise amplifier for amplifying power while minimizing noise of a signal filtered by the phase locked loop.

    摘要： Provided are a receiving circuit including a balun circuit and a notch filter, and an operating method thereof. The receiving circuit includes a transformer, a notch filter, and a mixer. The transformer converts a single input signal to a differential input signal using a first tap. The notch filter blocks a specific frequency band of the single input signal by connecting a second tap with the first tap of the transformer using a condenser.
