Abstract

A 75~115GHz power combined frequency sextupler is developed with hybrid integrated technology.The frequency of the input Ku-band signal is doubled by an active doubler

and then its output power is amplified to 24dBm.The power is applied to pump 75~115GHz tripler in which the varistor multiplying diode is realized by GaAs foundry of Nanjing electronic devices institute (NEDI)

and the tripler output power is combined.Considering parasitic parameters of the diodes

diode input and output optimum impedance is calculated with embedding analysis for matching circuit optimization.Measured results indicate the output power of the sextupler is higher than 8.0dBm

and power response is flat in 75~115GHz.The highest tested power is 10.2dBm at 110GHz

and combined multiplying efficiency is higher than 1.3%.The sextupler performance achieves the level of similar foreign products

which can expand the existing microwave signals to 75~115GHz and be applied for W-band TR modules.
