Abstract: A radiofrequency (RF) receiver circuit and method offer one or more performance improvements, such as an increased input compression point through better out-of-band interference suppression. In one example, an RF receiver circuit includes a low-noise amplifier (LNA) circuit and a mixer. The mixer output signal serves as negative feedback to the LNA circuit for improved compression point performance at interferer frequencies in or out of band with respect to a frequency of interest. Compression point performance is further improved for interferer signal components away from the frequency of interest by including at least one frequency-dependent circuit in the LNA circuit that is configured to reduce amplifier gain for such frequencies. The frequency-dependent circuit(s) may be tunable for different frequencies of interest. Additional improvements may be obtained by including a broadband input matching circuit and/or by including active mixer loads to increase the voltage conversion gain of the RF receiver circuit.

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 configured 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 configured to block passage of receive frequency signals between the signal transmission and reception arrangement and the transmitter. One of the frequency blocking arrangements comprises a network of passive components including at least one transformer and a filter arrangement with a higher impedance at the blocking frequency interval than at the non-blocking frequency interval.
