Varicap Diode Used Adaptive Band-Pass Filter Design Operating in the Frequency Range of 700 MHz-1800 MHz

Abstract

Filters play an important role in wireless communication systems. For this reason, filters with different physical properties according to the operating frequency are widely designed and used. Since the physical properties of the filters prepared by traditional methods are fixed, their operating frequencies are also fixed. In this study, microstrip adaptive filter design was carried out for the RF/Microwave region. Thanks to the adaptability of the prepared filter, the applied supply voltage is changed, allowing the filter to operate at different frequencies without changing its physical properties. In the simulation studies of the filter, the ADS program, which is an RF/Microwave circuit design and simulation program produced by Keysight Technology, was preferred. As a substrate material in the filter, known as FR4 in the market; A base material with a loss tangent value of 0.035, a dielectric material thickness of 1.6 mm, and a dielectric constant of 4.3 was used. SMV 1249 varicap diode was added to the prepared filter. Different voltages between 0V and 14V were applied to the ends of the diode and S11 and S21 parameters were recorded for each case. The measurements of the circuit were made with Rohde & Schwarz FSH6 spectrum analyzer. It has been observed that the prepared microstrip filter can be used as a band-pass filter between 700MHz and 1800MHz, including GSM frequencies.

Öz

Kablosuz haberleşme sistemlerinde filtreler önemli yer tutmaktadır. Bu sebeple çalışma frekansına göre farklı fiziksel özelliklere sahip filtreler yaygın olarak tasarlanıp kullanılmaktadır. Geleneksel yöntemlerle hazırlanan filtrelerin fiziksel özelliği sabit olduğu için çalışma frekansları da sabit olmaktadır. Bu çalışmada RF/Mikrodalga bölgesi için mikroşerit adaptif filtre tasarımı gerçekleştirilmiştir. Hazırlanan filtrenin adaptifliği sayesinde, uygulanan besleme gerilimi değiştirilerek, filtrenin fiziksel özelliklerini değiştirmeden farklı frekanslarda çalışabilmesi sağlanmıştır. Filtrenin benzetim çalışmalarında Keysight Teknoloji’nin ürettiği ve bir RF/Mikrodalga devre tasarım ve benzetim programı olan ADS programı tercih edilmiştir. Filtrede alttaş malzeme olarak, piyasada FR4 olarak bilinen; kayıp tanjant değeri 0,035, dielektrik malzeme kalınlığı 1,6mm, dielektrik sabiti 4,3 olan taban malzemesi kullanılmıştır. Hazırlanan filtreye SMV 1249 varikap diyodu ilave edilmiştir. Diyodun uçlarına 0V ile 14V arasında farklı gerilimler uygulanmış ve her durum için S11 ve S21 parametreleri kaydedilmiştir. Devrenin ölçümleri ise Rohde & Schwarz FSH6 spektrum analizör ile gerçekleştirilmiştir. Hazırlanan mikroşerit filtrenin mevcut hali ile GSM frekanslarını da içeren 700MHz ile 1800 MHz arasında Band geçiren filtre olarak kullanılabileceği gözlenmiştir.
