Abstract: A millimeter wave (mmW) communication system located on a millimeter wave integrated circuit (MMW-IC) includes a phase shifter selectively connected to a receive path by a first electromagnetic (EM) element and selectively connected to a transmit path by a second EM element, the first EM element configured to receive a transmit signal and configured to receive a receive signal from a low noise amplifier (LNA), the second EM element configured to receive a phase shifted transmit signal or a phase shifted receive signal from the phase shifter, and wherein the second EM element is configured to selectively provide the phase shifted transmit signal to a power amplifier on the mmW-IC and the phase shifted receive signal to receive signal processing circuitry located off of the mmW-IC.

Abstract: Aspects include amplifiers with different units for improved performance. One amplifier has a first transistor with first gate is coupled to a control input, and a first drain is coupled to a first terminal of an output, a second transistor with a second gate is coupled to the control input, and a second drain is coupled to a second terminal of the output. The amplifier has a third transistor with a third drain coupled to the first transistor source, and a third gate is coupled to a first terminal of an input, and a fourth transistor with a fourth drain is coupled to the second transistor source, and a fourth source gate is coupled to a second terminal of the input, where the first transistor source is not connected to the second transistor drain via one or more transistors.

Abstract: A method of self-testing a transceiver integrated circuit substrate includes: providing a test signal to a transmission line that is communicatively coupled, or selectively communicatively coupled, to an input of a power amplifier of a first transceiver subcircuit of the transceiver integrated circuit substrate; providing the test signal from the transmission line to an LNA of an LNA of a second transceiver subcircuit of the transceiver integrated circuit substrate; and measuring the test signal before amplification by the LNA, or after amplification by the LNA, or both.

Abstract: Aspects of the present relate to reflection type phase shifters for radio frequency (RF) wireless devices. Reflection type phase structures in accordance with aspects described herein can improve device performance with compact configurations, such as where magnetic and capacitive coupling is integrated into a device design to integrate interactions between elements for improved phase shifting performance in a compact design with wideband performance.
