WLAN Uygulamaları için Güç Kuvvetlendirici ve Düşük Gürültülü Güç Kuvvetlendirici

Abstract

2.45 GHz frekansında çalışan WLAN uygulamaları haberleşme araçlarında sıkça kullanılan bir iletişim yöntemidir. Erişim noktaları ile akıllı cihazların arasında gerçekleşen veri gönderimi ve alımı için bağlantı fonksiyonları da WLAN teknolojisi ile gerçekleşir. Veri transferindeki iletişim kalitesi bu teknoloji içinde her aşamada önem arz etmektedir. Verimi doğrudan etkileyen kaliteyi artırmak için ön-uç modül yapıları kullanılmaktadır. Güç kuvvetlendirici (GK), düşük gürültülü güç kuvvetlendirici (DGGK), anten ve süzgeç içeren devreler ön-uç yapılarının en önemli bileşenlerini oluşturur. Bu çalışmada, PW570 kazanç bloğu kullanılarak GK ve BFP760 RF transistör devresi kullanılarak DGKK önerilmiştir. Önerilen yeni devrelerin kullanılması sayesinde WLAN performans etkenlerinden olan veri iletişim hızında ve kapsama alanında önemli iyileşmeler olacaktır.

Power Amplifier and Low Noise Amplifier for WLAN Applications

Abstract

WLAN applications operating at a frequency of 2.45 GHz are a frequently used communication method in transmission tools. The connection functions to send and receive data between access points and smart devices are also fulfilled by WLAN technology. Communication quality in data transfer gains importance for this technology at every stage. Front-end module structures are used to increase such quality affects directly the efficiency. Circuits including power amplifier (PA), low noise amplifier (LNA), antenna and filter are the most significant components compose front-end structures. In this study, PA and LNA using PW570 gain block & BFP760 RF transistor circuit respectively are proposed. By means of the usage of the proposed circuits, there will be considerable improvements in data communication speed and area of coverage, which are among the WLAN performance factors.
