摘要： A lightweight millimeter wave outdoor unit includes a lightweight housing with a heat sink and mounting member configured for mounting on the antenna to form a wireless link. A millimeter wave transceiver board is formed of ceramic material and mounted within the housing. It includes a millimeter wave transceiver circuit that has microwave monolithic integrated circuit (MMIC) chips and operable with the transmit and receive boards. An intermediate frequency (IF) board has components forming an intermediate frequency circuit operable with the millimeter wave transceiver circuit. A frequency synthesizer board has a signal generating circuit for generating local oscillator signals to the transceiver circuit. A controller board has surface mounted DC and low frequency discrete devices thereon forming power and control circuits that supply respective power and control signals to other circuits on other boards. A quick connect/disconnect assembly is operative with the housing for allowing the housing to be rapidly connected and disconnected to the antenna circuit contact members interconnect circuits between boards.

摘要： A high frequency signal source and method of generating a high frequency signal is disclosed. An output signal is generated from a dielectric resonator oscillator and mixed with an output signal from a voltage controlled oscillator having a predetermined tuning range and part of a phase locked loop circuit to sum the frequencies for creating a final output frequency. A portion of the final output frequency is coupled into the phase locked loop circuit that is phase locked to a reference signal from a crystal reference oscillator. The voltage controlled oscillator has a tuning range that is used to compensate for the dielectric resonator oscillator initial frequency error and drift over temperature and aging while the balance of the bandwidth is used to provide the tuning range on the local oscillator output. The phase locked loop circuit is phase locked to the reference crystal oscillator that is used to compensate for any initial dielectric resonator oscillator frequency errors because of manufacturing and for any drift because the temperature changes or aging.

摘要翻译：公开了一种产生高频信号的高频信号源和方法。输出信号从介质谐振器振荡器产生，并与来自具有预定调谐范围的压控振荡器的输出信号和锁相环电路的一部分混合，以求出用于产生最终输出频率的频率。最终输出频率的一部分被耦合到相位锁定到来自晶体参考振荡器的参考信号的锁相环电路中。压控振荡器具有调谐范围，用于补偿介质谐振器振荡器初始频率误差和温度漂移和老化，而平衡带宽用于提供本地振荡器输出上的调谐范围。锁相环电路被锁相到参考晶体振荡器，用于补偿由于制造而导致的任何初始介质谐振器振荡器频率误差，并且由于温度变化或老化而导致任何漂移。
