Abstract

In this study, an ultra-compact monolithic microwave integrated Wilkinson power divider circuit was designed for X-band applications. Miniaturization technique was utilized to reduce the size of the power divider and the results of the proposed technique was analyzed with simulation software. The proposed Wilkinson power divider was fabricated using gallium nitride (GaN) integrated passive device technology. According to the measurement results, it was seen that the input and output (I/O) reflection coefficients were better than -14 dB in the X band region (8-12 GHz). In the same frequency range, the transmission coefficient was measured above -4.7 dB. In the study, the 10 dB fractional bandwidth was calculated as 47.6%. By applying the 𝜋-type miniaturization technique with monolithic lumped elements, the size of the Wilkinson power divider was reduced to 776 µm x 2240 µm. With the method proposed in this study, the power divider has been made compact in size without occuring any deterioration in its electrical performance.

Özet

Bu çalışmada, X-bant uygulamaları için ultra kompakt monolitik mikrodalga entegre Wilkinson güç bölücü devresi tasarlanmıştır. Tasarımın boyutunu küçültmek amacıyla minyatürleştirme tekniği kullanılmış ve önerilen tekniğin verileri simülasyon programı ile analiz edilmiştir. Önerilen Wilkinson güç bölücü, galyum nitrür (GaN) entegre pasif cihaz teknolojisi kullanılarak üretilmiştir. Elde edilen ölçüm sonuçlarına göre X bandında (8-12 GHz), giriş ve çıkış (I/O) yansıma katsayılarının -14 dB’den daha iyi olduğu görülmüştür. Aynı frekans aralığında iletim katsayısı ise -4,7 dB’nin üzerinde ölçülmüştür. Çalışmada 10 dB’lik kesirli bant genişliği %47,6 olarak hesaplanmıştır. Monolitik toplu elemanlar ile 𝜋 tipi minyatürleştirme tekniği uygulanarak Wilkinson güç bölücünün boyutu 776 µm x 2240 µm’ye düşürülmüştür. Bu çalışmada önerilen yöntemle, güç bölücü devresi elektriksel performansında herhangi bir bozulma olmadan boyut olarak kompakt hale getirilmiştir.
