A semiconductor chip includes a first wireless communication circuit, a local oscillator (LO) buffer, and an auxiliary path. The first wireless communication circuit has a signal path, wherein the signal path has a mixer input port and a signal node distinct from the mixer input port. The auxiliary path is used to electrically connect the LO buffer to the signal node of the signal path. The LO buffer is reused for a transmit (TX) function through the auxiliary path.

A novel and useful discrete time IIR bandpass filter is disclosed that takes advantage of clock phase reuse thereby leading to significant improvements in filtering, especially stop band rejection in comparison to prior art filters. The bandpass filter of the present invention achieves improved filtering performance without adding any additional clock phases to the circuit. In particular, reuse of the already existing clock phases increases the order and performance of the filter. The invention exploits reuse of the clock phases to provide higher order filtering along with a discrete time IIR filter design which is capable of operating at high frequency. Consequently, much better filtering is achieved and the quality factor of the filter is improved leading to sharper transition bands especially for close-in band blockers in modern 4G/5G receivers.

A method related to processing interference between cooperative radars, where a radar obtains configuration information used to indicate a ratio of a quantity of first data update periods to a quantity of second data update periods in a sending period. The first data update period is used to send a first radio signal, and the second data update period is used to send a second radio signal. Waveform configurations of the first radio signal and the second radio signal are different, to effectively reduce mutual interference between the first radio signal and the second radio signal.
