Benefits of technology

[0010]According to a fourth aspect of the present disclosure, a radio frequency (RF) circuital arrangement is presented, the arrangement comprising: a transmit path configured to transmit, during a transmit mode of operation of the RF circuital arrangement, a transmit RF signal at a transmit/receive port of the RF circuital arrangement; a receive path configured to receive, during a receive mode of operation of the RF circuital arrangement, a receive RF signal at the transmit/receive port, and a tunable notch filter configured to reduce a radio frequency interference of the transmit RF signal over the receive RF signal, wherein during operation, the RF circuital arrangement is configured

Problems solved by technology

Radio frequency (RF) devices, such as cell phone transmitters, are becoming increasingly complex due to additional frequency bands, more complex modulation schemes, higher modulation bandwidths, and the introduction of data throughput improvement schemes such as simultaneous RF transmission and/or reception within a same or different, but closely spaced, bands or channels within a band (e.g. voice, data), and aggregate transmission wherein information is multiplexed over parallel RF transmissions.
