NRD GUIDE MICROSTRIP LINE TRANSITION INCLUDING NRD GUIDE DIELECTRIC LINE, MODE SUPPRESSOR, DIELECTRIC BLOCK, FEEDER LINES AND MATCHING TRANSMISSION METAL BLOCKS

摘要

PURPOSE: An NRD(non-radioactive dielectric) guide microstrip line transition is provided to reduce a signal noise level and increase gains by mounting a power amplifier and a low noise amplifier to an NRD guide transmitting/receiving terminal. CONSTITUTION: An NRD guide microstrip line transition comprises an NRD guide dielectric line(3), a mode suppressor(4), a dielectric block(5), feeder lines(6a,6b) and matching transmission metal blocks(7a,7b) which are arranged between an upper metal conductor plate(1) and a lower metal conductor plate(2). The feeder lines are inserted in the dielectric block, and the matching transmission metal blocks allow for passages of the feeder lines. A microstrip line or a co-planar line is impedance-matched with the feeder lines, centering from the matching transmission metal blocks.
