A phase array antenna system includes a first panel comprising a first array of antennas in a first grid pattern for transmitting first signals, and a second panel comprising a second array of antennas in a second grid pattern for receiving second signals. The first panel and the second panel are fixedly disposed in a plane and co-located along a direction in in the plane. The first grid pattern is the same as the second grid pattern, and the first panel and the second panel are rotated by an angle.

Phase array antenna system and phase array antenna for improved transmission and reception isolation

A full duplex communication system comprises a magnet-less ring circulator that comprises a set of ports extending from a circumference of the magnet-less multi-port ring combiner. The set of ports are positioned at increments around the circumference of the magnet-less multi-port ring combiner.

Magnet-less ring circulators for full duplex division wireless communication

A magnet-less multi-port ring combiner comprises a set of ports extending from the circumference of the magnet-less multi-port ring combiner. The set of ports are positioned at &#xbc; increments around the circumference of the magnet-less multi-port ring combiner. The set of ports comprise a first input port configured to receive a first input signal and a second input port configured to receive a second input signal, wherein the first input signal is 180&#xb0; out-of-phase with the second input signal. The N-way magnet-less multi-port combiner comprises more than four ports.

N-way ring combiner/divider

An electronic switch for switching between signal outputs comprises a 6-way symmetric hybrid ring combiner. Each port within the 6-way symmetric hybrid ring combiner is positioned at &#x3bb;/4 wavelength increments around a circumference of the 6-way symmetric hybrid ring combiner.

Low-insertion-loss triple throw switch

Embodiments include different multi-port ring combiners which are configured to act as multi-output signal routers. One type of multi-port ring combiner includes input ports that are driven by pairs of outphasing signals. The multi-port ring combiner also includes multiple channels that are independently routed to a first output, to a second output, or to a third output, according to a phase relationship of the multi-port ring combiner. The multi-port ring combiner enables an outphasing signal combination which provides output port selection. The multi-port ring combiner may be a 4-port ring combiner, a 5-port ring combiner or a 6-port ring combiner.

Channel combiner supporting simultaneous multi-channel operation

Spatially combining signals may include receiving a number of RF input signals at a number of RF input connectors. At least one of the RF input signals is a variable envelope signal. A variable envelope signal is converted into two or more outphased constant envelope signals. The two or more outphased constant envelope signals are amplified. The amplified outphased constant envelope signals are radiated. At a spatial combiner aperture, the radiated amplified outphased constant envelope signals are combined to create a combined signal. The combined signal is output onto an output RF connector.

Outphased spatial combiner

A circuit card can include a circulator for routing a signal from a first amplifier to an antenna and for routing a signal from the antenna to a second amplifier, replacing a traditional transfer switch. The circulator can be a surface mount element to enable the circulator, first amplifier, and second amplifier to be mounted on the same circuit card thereby minimizing the size of a transceiver that employs the circuit card. Multiple circulators can be included on the same circuit card to allow for multi-band operation.

Circulator used as a high power TX/RX switch

A multi-path receiver for automated test equipment. The multi-path receiver includes an input for receiving low-power signals and high-power signals. The high-power signals have signal amplitude higher than the low-power signals. The multi-path receiver further comprises an output for outputting a received signal, a first path for transmitting a received high-power signal from the input to the output and a second path for transmitting a received low-power signal from the input to the output. The second path comprises an amplifier. A first switch is provided for switching a received high-power signal to the first path and for switching a received low-power signal to the second path. A high-power amplifier is also connected between the input and the first switch for amplifying the received signal independent of its input power before it is switched with the first path or the second path.

Optimized automated test equipment multi-path receiver concept

A signal coupler can couple a processed version of an outgoing signal from a transmission path to a receive path in a transceiver. A connector can provide the processed version of the outgoing signal to a pre-distortion module, which can generate a pre-distortion signal to pre-compensate outgoing signals in the transmission path of the transceiver. A receive path of a transceiver can thus be utilized as a feedback path to a pre-distortion module.
