  Abstract

This paper proposes a novel BPF structure with less insertion loss and small size instead of the existing coupled line BPF for the output of the tripler using APDP (Anti-Parallel Diode Pair). This proposed BPF consists of the interdigital capacitor and spiral open stub. The proposed BPF has the insertion loss of less than 0.7 ㏈ within the band (16.41 ~ 19.23 ㎓). The conversion loss of the tripler is about 16.6~18.5 ㏈ (flatness<±1 ㏈) at 5.72 ~ 6.28 ㎓ of fundamental frequency. Its fundamental frequency and the fifth harmonic suppression characteristic at 6㎓ are -32.16 ㏈c and -44.6 ㏈c, respectively. And its phase noise attenuation characteristic is about 9.5 ㏈ at 100 ㎑.
