Chebyshev Filter

AbstractGap waveguide technology is particularly attractive for the design of passive elements in mm-wave systems. Recently, the so-called zero-gap implementation has proved to be very robust to manufacturing tolerances, while at the same time keeping the low loss associated to the contactless standard gap waveguide. In this paper, a Chebyshev filter working at 145 GHz based on this idea and intended to be used in a wireless communication system is designed and optimized. A conventional milling technique has been used in its fabrication, and good measured results have been obtained in a single-pass process.

Wireless Communication System

This work investigates ultra-small size, high-performance, solenoid-type RF chip inductors for wireless communication system application. The materials (96wt% Al2O3) and shape (I-type) of the core, the diameter (40 µm) of the coil, and the length (0.35 mm) of solenoid were determined by a Maxwell three-dimensional (3D) field simulator to maximize the performance of the inductors. The dimensions of the RF chip inductors fabricated were 1.0 mm×0.5 mm×0.5 mm and copper (Cu) coils were used. The high-frequency characteristics of the inductance (L) and quality factor (Q) of the developed inductors were measured using a RF impedance/material analyzer (E4991A with an E16197A test fixture). The developed inductors with 6 coil turns exhibit an inductance of 11 to 11.3 nH, have a quality factor of 22.3 to 65.7 over the frequency ranges of 250 MHz to 1.7 GHz, and show results comparable to those measured for the inductors prepared recently by CoilcraftTm. The simulated data predicted the high-frequency data of the L and Q of the inductors developed well. It was suggested from the equivalent circuit model of the developed inductors that the developed inductors with 6 turns have a self-resonant frequency of 8 GHz.
