摘要： A transceiver front-end of a communication device is disclosed. The transceiver front-end is connectable to a signal transmission and reception arrangement adapted to transmit a transmit signal having a transmit frequency and to receive a receive signal having a receive frequency, to a transmitter adapted to produce the transmit signal, and to a receiver adapted to process the receive signal. The transceiver front-end comprises at least one of a transmit frequency blocking arrangement and a receive frequency blocking arrangement. The transmit frequency blocking arrangement has a blocking frequency interval associated with the transmit frequency and a non-blocking frequency interval associated with the receive frequency, and is adapted to block passage of transmit frequency signals between the signal transmission and reception arrangement and the receiver. The receive frequency blocking arrangement has a blocking frequency interval associated with the receive frequency and a non-blocking frequency interval associated with the transmit frequency, and is adapted to block passage of receive frequency signals between the signal transmission and reception arrangement and the transmitter. At least one of the transmit frequency blocking arrangement and the receive frequency blocking arrangement comprises a network of passive components comprising at least one transformer and a filter arrangement adapted to have a higher impedance value in the blocking frequency interval than in the non-blocking frequency interval.

摘要： In a method of frequency down-converting an input signal to an output signal, a first local oscillator signal is generated as a square wave having a duty cycle of 1/3 or 2/3, and the input signal is mixed with the first oscillator signal to achieve a first down- converted signal, A second local oscillator signal is generated as a modified square wave having the same period time and a duty cycle of 2/3, of which one part has a positive amplitude and another part has a negative amplitude. The input signal is mixed with the second oscillator signal to achieve a second down-converted signal. The first oscillator signal has a delay of ¼ of the period time to achieve a phase shift of π/2 between the oscillator signals, and at least one down-converted signal is multiplied by a pre-calculated factor. The resulting down-converted signals are added to achieve the output signal.
