Abstract
PURPOSE:To attain isolation among input ports of local oscillation signals, an input port of a high frequency signal, and a mixer output part between local oscillation signals and the high frequency signal by canceling both local oscillation signals appearing in a first input terminal and a common connection part by each other. CONSTITUTION:First and second local oscillation signals which have the same frequency and are different in phase by 180 deg. are inputted to a second input terminal 18 and a third input terminal 32 of an annular strip line. Consequently, both local oscillation signals are canceled by each other in a first input terminal 12 of the high frequency signal which is 1/2lambda distant from second and third input terminals 18 and 32, and similarly, both local oscillation signals are canceled by each other in a mixer output part 24 which is 1/4lambda distant from second and third input terminals 18 and 32. Thus, isolation among input ports of local oscillation signals, the input port of the high frequency signal, and the mixer output part 24 between local oscillation signals and the high frequency signal is attained.
