The invention discloses a withstanding power THz (terahertz) triple frequency analogous balance type doubling circuit, relating to the THz circuit technical field, and comprises a radio frequency input waveguide, a quartz substrate and a radio frequency output waveguide; the anode of a multijunction GaAs THz frequency doubling diode which has the cathode connected to a radio frequency matching microstrip line is in connection with a direct current bias end quartz strip line; each direct current bias end quartz strip line is in connection with one end of a capacitor through a gold wire jumper, and the other end of the capacitor is in connection with a same input microstrip line integrated with a low pass filter through the gold wire jumper. The withstanding power THz triple frequency balance type doubling circuit has a simple circuit structure, and can bear larger input power due to the increase of schottky diodes, and realize more stable circuit operation in an analogous balance type frequency doubling mode f
