Abstract: Radar circuitry can include an isolator and a mixer. The isolator can isolate a transmission signal path and a reception signal path from each other, and generate a mixing (e.g. oscillation) signal based on a transmission signal. The isolator can be coupled to the mixer such that the drive signal drives the mixer (e.g. serves as the local oscillation signal of the mixer). The mixer mixes a received signal and the drive signal to generate a converted signal (e.g. a down-converted signal). The isolator can be a hybrid transformer or electrically balanced duplexer.

Abstract: A transmit receive switch (TRSW) system is disclosed. The system has a transmission line, a transformer based matching network, a shunt switch, an amplifier and circuitry. The transmission line is connected to an antenna port. The transformer based matching network is connected to the transmission line and has a first coil and a second coil, wherein the second coil is connected to the transmission line. The amplifier can be configured as a shunt switch when inactive. The shunt switch, including the amplifier configured as the shunt switch, can be connected to the first coil of the transformer based matching network. The circuitry is configured to cause the shunt switch to be ON during an inactive mode and create a short across the first coil. Combined, the length of transmission line needed to complete the impedance transformation is reduced, thereby lowering the overall insertion loss of the transmit/receive switch.

Abstract: A receiver system includes a blocker detector circuit configured to receive a radio frequency (RF) input signal and detect an existence of a blocker therein, and further configured to output a blocker detection signal indicative of the existence of the blocker. The receiver system further includes a configurable receiver circuit configured to receive the RF input signal and the blocker detection signal, and selectively configure the configurable receiver circuit between a first mode wherein the configurable receiver circuit exhibits first linearity characteristics, and a second mode wherein the configurable receiver circuit exhibits second, different linearity characteristics based on the blocker detection signal.
