description |
Compact mIcrowave hairpin band pass filter using half-wavelength folded
resonator as a method to miniaturize resonator structure has been thoroughly studied in
this thesis. Design were done by using the mathematic formulas and verified by using
SONNET LITEPlus 8.0 software. Synthesis of the filter is using the insertion loss
method. The initial design of a miniature hairpin filter was achieved by carefully
selecting the resonator shape and the initial frequency. The shape was then fine tuned,
and the response for the changes was plotted. This would indirectly represent the
behavior of the circuit when parameter variation occurs. The step by step procedure to
design the filter is presented. The design performance and characteristics in terms of
electrical and physical parameters were compared with the conventional hairpin filter.
The final design of the miniaturized hairpin filter has an overall size of 46% smaller
compared to the conventional hairpin size. Better return loss properties were also
observed from the miniaturized version. The first spurious frequency occurs at a higher
frequency compared to that of the conventional hairpin filter. It is tunable depending on
the value of the even-mode impedance that was chosen at the early stage of the design
process. The bandwidth, however, was slightly narrower, which is 80% of the
desired 1 00 MHz. In terms of the response, miniaturized hairpin filter is having steeper
skirting. However, it is comparable to that of the conventional hairpin filter. |
