NRD GUIDE TRANSCEIVER, DOWNLOAD SYSTEM USING THE SAME, AND DOWNLOAD MEMORY USED FOR THE SAME

摘要

There are provided an NRD guide transceiver not requiring a transmission/reception selector switch, a download system capable of downloading large-capacity data such as video data in a short time with a simple structure using the NRD guide transceiver, and a download memory used for this. A pair of dielectric strips (154, 155) is arranged between two conductor plates (152, 153) arranged at a predetermined interval and parallel to each other. A shot key barrier diode (156, 157) is connected to each end of the pair of dielectric strips (154, 155). A low pass filter (164) is connected to the signal input terminal while a high pass filter (165) is connected to the IF output terminal.
