Abstract: A system and apparatus is provided to reduce signal routing, area and signal loss in double-pole, double-throw (DPDT) switch implementations in wireless and millimeter-wave front ends. A staggered arrangement of receivers, transmitters and antenna ports connecting with DPDT switches reduce signal cross-over and allow for compact, low-loss multi-antenna configurations.

Abstract: Systems and methods are provided for millimeter-wave (MMW) communication, the system includes a transceiver chip to generate and to receive signals. An interface is used to communicate the signals between the transceiver chip and one or more active antenna modules. The signals include modulated MMW signals and control signals. The transceiver chip includes baseband circuitry, up and down conversion mixers, and RF front-end circuitry. An active antenna module receives a first modulated MMW signal from the interface for transmission via antennas and to receive a second modulated MMW signal from the antennas for transmission through the interface to the transceiver chip.

Abstract: A bidirectional time-division duplexing transceiver circuit includes a first and a second bidirectional phase-shift circuit, and a bidirectional amplifier circuit including a first amplifier circuit and a second amplifier circuit. The first amplifier circuit and the second amplifier circuit are coupled via double-pole-double-throw (DPDT) switches to radio-frequency (RF) antennas and the first and the second bidirectional phase-shift circuits. The (DPDT) switches enable the first amplifier circuit and the second amplifier circuit to be operable simultaneously as transmit (TX) path amplifiers in a first time slot and as a receive (RX) path amplifiers in a second time slot.
