Mixer circuit in CATV UP/DOWN converter

摘要

This mixer circuit is configured so that a second capacitor (C10 and C11) having capacitance smaller than that of a first capacitor (C1 and C3) is connected in parallel with the first capacitor (C1 and C3), the first capacitor (C1 and C3) being connected to output terminals of the diode bridge so that an anode and a cathode of respective diodes connected in series to constitute the diode bridge are made equal in electric potential to each other by the first capacitor (C1 and C3) in terms of radio frequency.
