First-Pass design of UWB Microwave and Millimeter-wave Filters for Multi-Stage Frequency Multiplication



H. M. Talasila, F. R. Morales, Nate Orloff, Dazhen Gu, C. Oakley, J. Paden, M. McKeown


Compact microwave and millimeter (mm-wave) wave filters with fractional bandwidths exceeding 20 % are in demand for applications such as wireless communications and radar. Microstrip (-strip) band-pass designs implemented using high-permittivity ceramic substrates have been widely reported in the literature [1-3]. However, some limitations of these earlier realizations include significant insertion loss, narrow bandwidth and limited selectivity [4-8]. To overcome the lack of commercial-off-the-shelf filters with very specific passbands and selectivity requirements in an accelerated development schedule, we rapid-prototyped a set of custom planar microstrip filters on Alumina substrates with fractional bandwidth exceeding 33 %. These ultra-wideband [9], low-loss ceramic filters are intended to serve as pre-select filters in a multi-stage frequency multiplier module used in the generation of highly-linear frequency sweeps for radar.
