Abstract:
The operation principles of the diplexers, based on the application of the properties of the quarter wave and half-wave of the trans-mission line segments are considered. The purpose of the executed work was study of principally new construction of the autonomus semiconductor diplexer, what provides extension of the operating frequency band of the diplexer almost to 200% while simultaneous ensuring autonomy of the operations, i.e. without input control signals, synchronized with transmitter impulse. The results of diplexer investigation for the ultrashort video pulses with a voltage limiter to protect receiver are obtained. The opportunity to protect ultra-broadband radar station receiver in the transmission mode when pulse duration of 1 ns and the amplitude up to 1 kV also in receive mode when the amplitude of the asynchronous interference up to 200 V are shown. The researches can be seen as the first stage of the development of an autonomous switch. On the second (last) stage of development it will be done the specific design and process optimization of the basic version, including monolithic integrated circuits technology.
