• In this paper, a compact and high selectivity millimeter wave on-chip band-pass filter using GaAs pHEMT technology is proposed. A compact lumped element unit, which consists of a series LC resonator and an extra capacitor, is used to produce a transmission zero near the pass-band without occupying much area. The proposed filter consists two of the proposed resonators. An additional series resonator is grounded to produce a transmission zero. The area of the proposed filter is only 0.816×0.607mm 2 . The presented filter is worked on 25.5 GHz, the 3-dB bandwidth is 21.5 GHz to 29.5GHz. The insertion loss is around 1.1dB, and the return loss is better than 17dB.
