摘要： A precision voltage clamp is provided that displays virtually no temperature dependence, and maintains a clamp voltage that varies by about 1 my for input voltages ranging from the onset of clamping to several volts above this input. In particular, a current mirror is used to ensure that the current densities in the clamping transistor, and the bias correcting transistor, are very close to equal once the clamping action begins. A small current may be injected into the programming side of the mirror which will turn on the mirror and the biasing transistor, making it much easier for the clamp to clamp and settle.
摘要翻译：提供了精确的电压钳位，几乎不显示温度依赖性，并保持钳位电压，该钳位电压从钳位开始到该输入以上几伏的输入电压变化约为1。特别地，使用电流镜来确保夹紧晶体管和偏置校正晶体管中的电流密度在夹紧动作开始之后非常接近于相等。可以将小的电流注入反射镜的编程侧，这将使反射镜和偏置晶体管接通，使得钳夹更容易夹紧和沉降。

摘要： A method and apparatus which enables a facility or entity that transmits and receives radar signals to receive any incoming radar signal, while blocking reception of any signals generated by the facility or entity itself. The method comprises transmitting a primary signal from an rf generator; providing a second signal which is synchronized with the primary signal matching in both phase and amplitude, but with a phase difference of 180 degrees so that the two signals sum to zero. The second signal travels through a voltage controlled attenuator and thru a voltage controlled phase shifter. Combining in a combiner the second signal with a signal radiated by a transmitting antenna and received by a receiving antenna that connects into a transmission enabling mechanism, and then transmitting the combined signal to a detector apparatus.
