    摘要: Various embodiments relate to a reconfigurable integrated digital Chireix out-phasing power amplifier for use in high power base stations is described and a related method of said design. The power amplifier may include a power transistor circuitry having plurality of power transistors and shunt-series circuitry (L1C1, L2C2), a broadband combiner having Chireix compensation elements, and an impedance matching filter. In one embodiment, the power amplifier is implemented in a real switch-mode to facilitate integration of the Chireix compensation elements so as to make the Chireix power amplifier tunable. A method of driving Chireix power amplifier structure is also described. In some embodiments, a variable supply voltage may power the transistor circuitry based on the desired output power of the Chireix power amplifier. In some embodiments, the variable supply voltage may depend upon an out-phasing angle between the two drivers in the transistor circuitry.

    摘要: A system and method for monitoring a premise in case of an emergency and enabling 2-way voice communications with an individual at every possible location within the monitored premises. The system utilizes a radio frequency 2-way wireless communication link from a centrally located Base Alarm Control Unit on the premise to plurality of Remote Alarm Control Units situated throughout the premise. Remote Alarm Control Units relay the information received from the wireless remote transmitters to the Base Alarm Control Unit thereby increasing the effective useful range of the wireless communication link. The same also establishes a 2-way voice connection between the Central Station operator and the individual who may be located at any possible location within the premise, thereby providing a much more effective handling of the emergency or alarm situation.
