An interdigital microstrip coupled-line bandpass filter is proposed for millimetre-wave application. A quadruple-mode microstrip-line resonator is designed to constitute the passband. The interdigital coupled-line sections are designed as the input/output network of the resonator. Meanwhile, sharp selectivity of the passband is achieved.As design examples, the in-band and out-of-band performances of a filter prototype using low-cost single-layer microstrip-lines has been designed and experimentally examined. The measured results show that the filter achieves a passband insertion loss of 1.07 dB at 40 GHz, the lower-and upper-stopband rejections are larger than 18 dB and 3 dB fractional bandwidth is 20%.Introduction: The millimetre-wave (mm-W) band is popular owing to its merits of high data rate and saturation of frequency spectrum usage in lower frequency bands. However, mm-W passive components, e.g. the bandpass filter, are expensive and difficult to design owing to their small wavelength (in millimetres), which limits the design flexibility. There are numerous mm-W bandpass filters adopting different approaches to achieve high performance of the mm-W bandpass filter [1][2][3][4]. In this Letter, an interdigital coupled-line mm-W bandpass filter with a quadruple-mode resonator is proposed. The filter is designed using low-cost microstrip-line technology. A filter prototype is fabricated in a single substrate layer using low-temperature co-fired ceramic (LTCC) technology. The filter herein will be optimised using CST Studio [5], an electromagnetic (EM) simulator.

“…Remaining within a very straightforward and cost effective design as well as fabrication technique the demonstrated filter achieves promising performance in terms of BW and the out off band rejection with a reasonable insertion loss, which are quite acceptable and comparable or better than many results in costly thin film processes [9], LTCC and other SiP techniques reported at this frequency [1][2][3].…”

The design and performance of an embedded 60‐GHz planar coupled line bandpass filter in multilayer photoimageable thick‐film system‐in‐package technology is presented. The filter is designed employing open stubs to achieve low insertion loss of 3.4 dB, a return loss of −10 dB across wideband and good selectivity. This is one of the highest performance coupled line filters yet reported at V‐band for cost‐effective thick‐film based technologies. © 2011 Wiley Periodicals, Inc.

“…However, there are still many challenges in terms of packaging towards consumer applications and compact solutions. A highly integrated radio frequency (RF) module (also called system-in-package, SiP), which employs a multilayer structure, is effective in achieving the above requirements [3], [4], [5]. For designing compact modules, it is important to optimize the integration of all radio frequency (RF) active/passive components and power supply connections required.…”

For high-data-rate multimedia access and measurement applications (such as channel sounding and radar) the 60 GHz unlicensed band is of interest for short range applications. Currently, there is enormous progress in the field of monolithic-millimeter-wave-integratedcircuits (MMIC) for 60 GHz technology, but there are still many challenges related to reliability and usable bandwidth for compact packaging solutions. The aim of this work is to demonstrate the implementation of miniaturized 60 GHz front-ends, including fully differential MMICs, with gain control and phase-shifting capabilities, interconnected to a broadband differentially fed waveguide for the WR-15 standard. The front-ends were designed based on MMICs using 0.25 μm SiGe BiCMOS and packaging on low-temperature-cofiredceramics (LTCC) technology. We have designed, simulated, fabricated, and tested the front-ends showing a useable bandwidth of more than 12 GHz at the 60 GHz band fulfilling the requirements of the IEEE 802.11ad standard.
