Abstract

PURPOSE:To enable to measure the rectified current independently of each diode, by forming the DC circuit connecting choke coil to each of mixer diodes. CONSTITUTION:The input high frequency signal is input to the 3dB hybrid coupler 3. The local oscillation signal is input to the hybrid coupler 5. The middle point of the hybrid coupler 5 is grounded with the choke coil 33. High frequency and local oscillation signals are mixed at the mixer diodes 8-11, and the intermediate frequency signal is picked up from the terminal 17. Low pass filter is connected to the output side of each mixer diode and further, choke coils 23, 24, 27, 28 are connected. The rectified current of mixer diodes can easily be checked by measuring the current of DC closed circuit formed with each choke coil.
