Abstract

In this study, DC conditions (V DC ) and RF input power (P input ) of SBB5089Z power amplifier (PA) module that operates 50MHZ-6GHz frequency interval, have changed. RF P input have changed from -20dBm to 10dBm with 2dB steps, as well as V DC has changed with 75mV steps-6 bit resolution- from 0V to 5V. P output , gain (G) and power added efficiency (PAE (%)) have investigated graphically according to varying RF P input and V DC at 3.5GHz and 5.8GHz WiMAX frequencies. RF P input of PA module conditions have manually changed with RF signal generator, as well as DC conditions have changed with Arduino biasing control unit which includes R/2R digital analog converter (DAC) and LM324 voltage follower. According to the data obtained in this study, it has been observed that behavior of P output , G and EGV (%) have changed positively according to the increase of P input up to 1dB gain compression point (P 1dB ) and V DC values increased up to 5V.

Özet

Bu çalışmada 50MHZ-6GHz frekans aralığında çalışan SBB5089Z Güç Yükselteci (GY) modülünün, RF giriş gücü (P giriş ) -20dBm’den 10dBm’e kadar 2dB’lik artış ile ve besleme gerilim değerleri (V DC ) 0V’dan 5V’a kadar 75mV’luk adımlarla değiştirilmiştir. Çalışmada değişen V DC ve P giriş değerlerine göre P çıkış , kazanç (G) ve eklenmiş güç verimliliği (EGV (%)) grafikleri 3.5GHz ve 5.8GHz WiMAX frekanslarında ayrı ayrı incelenmiştir. Değişen RF P giriş ve V DC değerlerine göre GY modülü P giriş -V DC ’ye karşılık P çıkış , G ve EGV (%) grafikleri ayrı ayrı incelenmiştir. GY modülü RF P giriş koşulları manuel olarak RF sinyal jeneratörü ile DC gerilim değerleri ise Arduino’lu R/2R sayısal analog dönüştürücü (SAD) ve LM324 gerilim izleyici devresi kullanılarak değiştirilmiştir. Çalışmada elde edilen verilere göre 1dB kazanç sıkıştırma noktasına (P 1dB ) kadar artırılan P giriş değerlerine ve 5V’a kadar artırılan V DC değerlerine göre GY P çıkış , G ve EGV(%) davranışının olumlu yönde değiştiği gözlenmiştir.
