A dual beam dual-selectable-polarization phased array antenna comprises an aperture unit, a printed wiring board, radiating elements, chip units, a pressure plate, and a rear housing unit. The printed wiring board has sub assemblies bonded to each other with a bonding material providing both mechanical and electrical connection. The printed wiring board is connected to the aperture unit. The radiating elements are formed on the printed wiring board. The chip units are mounted on the printed wiring board. The chip units include circuits capable of controlling radio frequency signals radiated by the radiating elements to form dual beams with independently selectable polarization. The pressure plate is connected to the aperture unit. The aperture unit is connected to the rear housing unit such that the aperture unit covers the rear housing unit.

Dual beam dual selectable polarization antenna

The present invention provides a new architecture for MMIC circuitry that allows reception of electronically selectable single polarity for simultaneous dual polarity/dual beam signals by phased-array modules. Additionally, an improved phase shifter design that is smaller and requiring fewer electronic components than prior art phase shifters is disclosed. In particular, the phase shifter requires only a single control line for each stage of the phase shifter.

Dual polarization amplifier

The present invention provides a new architecture for MMIC circuitry that allows reception of electronically selectable single polarity or simultaneous dual polarity/dual beam signals by placed-array modules. Additionally, an improved phase shifter design that is smaller said requiring fewer electronic components than prior art phase shifters is disclosed. In particular, the phase shifter requires only a single control line for each stage of the phase shifter.

Monolithic microwave integrated circuits for use in low-cost dual

A bus leveling system for automatically monitoring and maintaining the amplitude of a radio frequency (RF) signal carded on a bus. A two-stage variable gain amplifier (64) is connected in series with the bus. Each stage of the variable gain amplifier is constructed with a PIN diode (84, 86) in a feedback path of the stage. The amplification of the variable gain amplifier is varied by the injection of current into the feedback path to adjust the resistance of the PIN diodes. A control circuit having an RE detector (78) is provided to monitor and adjust the gain generated by the variable gain amplifier. Preferably, the control circuit and the variable gain amplifier are incorporated into an Application Specific Integrated Circuit (ASIC) (62). The RF detector is constructed of two Gilbert multipliers (202, 204) to minimize errors caused by operating condition changes, including variations in power supply voltage, temperature, or process.
