Abstract

Equivalent circuit of a millimeter wave limiter is analyzed based on Butterworth (maximally flatness) low pass filter model.Considering the parasitic components of the limiter diodes

the whole limiter physical structure is setup.Diode parasitic parameters

bonding wire inductances

and complete limiter circuit matching networks are analyzed with EM software.A Ka full-band low insertion loss limiter is realized

the measured small-signal insertion loss is lower than 4.3dB in 26~40GHz

the lowest insertion loss is 2.2dB

and the VSWR is better than 1.95:1.At large signal condition with input continuous wave power of 0.5W

the peak leakage power is lower than 10.5dBm.The dimension of the limiter is 20?12?6mm

and its per

formance achieves the level of similar foreign products.
