摘要: In order to be able to use a selected one of two local oscillation signals with respective input terminals (2, 3), a microwave mixer has a radio frequency input terminal connected by way of a transmission line section (5) to one terminal of a mixer diode (6). The other diode terminal is connected to a quarter wavelength line section (7) and to an intermediate frequency output terminal (4) by way of a line section incorporating a low pass filter (10). Transmission line sections connected to the local oscillation terminals (2,3) are coupled to the quarter wavelength section (7) by respective distribution coupling type bandpass filters (8,9) tuned to the two different local oscillation frequencies.
