Broadband Pseudo High-pass Filter And Ultra-compact Dual-band Vco Developed

This thesis simply introduces the system of "RF synthesized sensor" at first. Based on the introduction it explores into the designing of the broad band filter and the super miniature of local oscillator source.The main work and achievements are as following:1) Proposed the approach to design the false high-passed broad band filter.2) Realized the HFSS(High Frequency System Simulate) of the strip-line filter.3) Discussed the process of designing and adjusting the "the strip-line filter" and analyze its essential theory4) Realized the non-line simulate of the ADS(Advanced Design System) of lumped parameter VCO and analyze the results of simulation and practical test.5) The arrangement of wires on PCB board of super-miniature VCO and put forward a proposal for the arrangement of wires on handmade PCB broadIn this paper, HFSS simulation software is combined effectively with algorithm based on practical theory. Furthermore, great emphasis is put on the keys to designing simulation. This paper also provides a good example for learning HFSS and ADS.The designing method put forward in this paper is of practicability, which is an available reference to the design of other transceiver of RF-synthesized sensor system and plays a positive role in the research process of RF-synthesized sensor.
