BANDPASS FLATNESS COMPENSATING CIRCUIT USING REFLECTIVE WAVEFORM GENERATOR

摘要

PURPOSE: A bandpass flatness compensating circuit using a reflective waveform generator is provided to simplify the design of the circuit and reduce insertion loss. CONSTITUTION: A bandpass flatness compensating circuit is provided with the first and second reflective waveform generator(22,23) having the characteristic of complementary reverse ripple waveform of a main system signal as a reflection loss characteristic, and a 3dB 90°hybrid coupler(21) for generation a reverse ripple waveform for compensating bandpass flatness in order to transform the reflection loss characteristic of the first and second reflective waveform generator into one transmission characteristic. At this time, the first and second coupling terminal(21c,21d) are connected with the first and second reflective waveform generator, respectively.
