|Title:||Output power performance of dual-fed and single-fed distributed amplifiers|
|Source:||Eccleston, K.W. (2000-11-20). Output power performance of dual-fed and single-fed distributed amplifiers. Microwave and Optical Technology Letters 27 (4) : 281-284. ScholarBank@NUS Repository. https://doi.org/10.1002/1098-2760(20001120)27:43.0.CO;2-R|
|Abstract:||It is well known that the dual-fed distributed amplifier utilizes all FET output power, whereas up to a half is wasted in the single-fed distributed amplifier. We show that both the single-fed and antiphase-input dual-fed distributed amplifiers are able to achieve power equalization among the FETs at microwave frequencies when the FETs are spaced 180°. Such power equalization allows identical (and optimum) load lines for all FETs. The dual-fed amplifier has the added advantage of being less affected by losses.|
