摘要： Systems and methods for utilizing universal frequency translators for phase detection and/or frequency detection. Phase and/or frequency detection can be utilized for comparing a higher frequency reference signal with a lower frequency local oscillator signal. Phase and/or frequency detection can also be utilized for phase locking and/or frequency locking. The systems and methods can be utilized to simultaneously down-convert a reference signal for phase and/or frequency comparison and/or for locking.

摘要： Systems and methods for a scalable architecture for radio device and systems are disclosed. This architecture employs a scalable bandwidth to deliver higher data rates and transmission ranges to devices that need them, while still delivering lower power solutions for devices which utilize a smaller bandwidth. These systems and methods may divide the available frequency spectrum into a set of fundamental sub-bands. Different devices may use various multiples of these sub-bands depending on their needs. Devices employing this architecture are also capable of interoperation with one another regardless of the bandwidth they utilize. A device may scan through each sub-band within which the device intends to operate, searching for a common beacon transmitted by other devices utilizing the sub-band. If a beacon is found the device can choose to interoperate with the other device or, alternatively, continue scanning the sub-bands until an unused sub-band is found.

IPC分类号： H03D7/00
摘要： A universal frequency translation module (UFT) frequency translates an electromagnetic (EM) input signal by sampling the EM input signal according to a periodic control signal (also called an aliasing signal). By controlling the relative sampling time, the UFT module implements a relative phase shift during frequency translation. In other words, a relative phase shift can be introduced in the output signal by sampling the input signal at one point in time relative to another point in time. As such, the UFT module can be configured as an integrated frequency translator and phase-shifter. This includes the UFT module as an integrated down-converter and phase shifter, and the UFT module as an integrated up-converter and phase shifter. Applications of universal frequency translation and phase shifting include phased array antennas that utilize integrated frequency translation and phase shifting technology to steer the one or more main beams of the phased array antenna.

摘要： A universal frequency translation module (UFT) frequency translates an electromagnetic (EM) input signal by sampling the EM input signal according to a periodic control signal (also called on aliasing signal). By controlling the relative sampling time, the UFT module implements a relative phase shift during frequency translation. In other words, a relative phase shift can be introduced in the output signal by sampling the input signal at one point in time relative to another point in time. As such, the UFT module can be configured as an integrated frequency translator and phase-shifter. This includes the UFT module as an integrated down-converter and phase shifter, and the UFT module as an integrated up-converter and phase shifter. Applications of universal frequency translation and phase shifting include phased array antennas that utilize integrated frequency translation and phase shifting technology to steer the one or more main beams of the phased array antenna.
摘要翻译：通用频率转换模块（UFT）频率通过根据周期性控制信号（也称为混叠信号）对EM输入信号进行采样来转换电磁（EM）输入信号。通过控制相对采样时间，UFT模块在频率转换期间实现相对相移。换句话说，通过在一个时间点相对于另一个时间点对输入信号进行采样，可以在输出信号中引入相对相移。因此，UFT模块可以被配置为集成频率转换器和移相器。这包括作为集成的下变频器和移相器的UFT模块，以及作为集成上变频器和移相器的UFT模块。通用频率转换和相移的应用包括利用集成频率转换和相移技术来引导相控阵天线的一个或多个主波束的相控阵天线。
