Spatial Power Combining for
s the operating frequency of semiconductor solidstate devices increases into the millimeterwave region, the size of the devices and their power handling capability are reduced. In order to provide the advantages of a solid-state technology for moderate power levels at millimeter-wave frequencies, solid-state components must be combined. Spatial power combining provides enhanced RF efficiency by...
متن کاملBroad-Band High-Power Amplifier Using Spatial Power-Combining Technique
High power, broad bandwidth, high linearity, and low noise are among the most important features in amplifier design. The broad-band spatial power-combining technique addresses all these issues by combining the output power of a large quantity of microwave monolithic integrated circuit (MMIC) amplifiers in a broad-band coaxial waveguide environment, while maintaining good linearity and improvin...

چکیده این پایان نامه به بررسی اثر سیم پیچ مغناطیسی و کاوه یِ خوشه گر با بسامد رادیویی بر هاله و بیرونگراییِ باریکه هایِ پیوسته و خوشه ایِ ذرات باردار در شتابدهنده های خطیِ یونی، پروتونی با جریان بالا می پردازد و راه حل هایی برای بهینه نگهداشتن این کمیتها ارایه می دهد. بیرونگرایی یکی از کمیتهای اساسی باریکه هایِ ذرات باردار در شتابدهنده ها است که تاثیر قابل توجهی بر قیمت، هزینه و کاراییِ هر شتابدهند...
Spatial power combining techniques for semiconductor power ampliiers
Growing demand on special signal modulation schemes in novel radars and ability to transmit relatively long pulses cause the Travelling Wave Tubes (TWT) to be constantly replaced by new concepts of power amplifiers. Solid-state power amplifiers appear to be a good candidate, however, the output power from a single transistor module is still relatively low. The only available solution is that of...
