Design and Engineering of highly selective compact SSS based mm-Wave BPF

Abstract

Paper discusses about the design, engineering of mm-Wave (34 – 36 GHz) BPF. Key challenge is designing a highly selective filter in compact size. It finds applications in high frequency front-end receivers, up/down-converters etc. The realized filter offers rejections >60dB at 10% away from band edges. Measured pass band insertion loss is < 3.6dB while measured return loss is >12dB. The filter is realized on 5 mils thick RF laminate with dielectric constant of 2.2. Realized filter size is 2.4x2.0x0.8cm3 and can be utilized as a stand-alone or drop-in module. The measured result is in good correlation with the simulated result.
