Abstract: In examples, an electronic device includes an antenna and a transmitter line. The transmitter line includes a double-tuned transformer having first and second windings, the first winding having first and second ends, the second winding having third and fourth ends, and the third end coupled to the antenna. The transmitter line includes a first capacitor coupled between the first and second ends. The transmitter line also includes a second capacitor coupled between the third and fourth ends, and a switch coupled between the first end and a reference terminal.

Abstract: A system includes a first differential amplifier and a first transformer with a primary coil coupled to an output of the first differential amplifier and with a secondary coil coupled to a load. The system also includes a second differential amplifier and a second transformer with a primary coil coupled to an output of the second differential amplifier and with a secondary coil coupled in series with the secondary coil of the first transformer. The system also includes a tuning network coupled to a center tap node between the secondary coil of the first transformer and the secondary coil of the second transformer.

Abstract: An apparatus includes a first primary coil, a second primary coil, and a secondary coil. The first and second primary coils each include a first, second, and third portion. The secondary coil includes a first and second portion in a first wafer layer, which are coupled together by a bridge in a second wafer layer. The second portion of the first primary coil is nested inside the first portion of the secondary coil in the first wafer layer. The second portion of the second primary coil is nested inside the second portion of the secondary coil in the first wafer layer. At least parts of the first and third portions of the first primary coil are adjacent the second portion of the secondary coil, and at least parts of the first and third portions of the second primary coil are adjacent the first portion of the secondary coil.

Abstract: A bidirectional phase shifter includes a differential quadrature hybrid coupler, a switch network, and a differential reflection type phase shifter (RTPS). The differential quadrature hybrid coupler includes a first phase input/output (I/O) port, an inverse first phase I/O port, a second phase I/O port, and an inverse second phase I/O port. The switch network is coupled to the first phase I/O port, the inverse first phase I/O port, the second phase I/O port, and the inverse second phase I/O port. The differential RTPS including a differential I/O port coupled to the switch network.

Abstract: An on-chip directional coupler includes a first linear conductive trace, a second linear conductive trace, and a conductive loop. The first linear conductive trace including an end and a coupled port. The second linear conductive trace is spaced apart from and parallel to the first linear conductive trace. The second linear conductive trace includes an end and an isolated port. The conductive loop includes a first end conductively coupled to the end of the first linear conductive trace, and a second end conductively coupled to the end of the second linear conductive trace.
