6. Design of a sharp response low-pass filter : through comparison of microwave design software
University essay from Avdelningen för elektronik, matematik och naturvetenskapAbstract : The aim of this thesis is to do a research about three microwave design software packages and evaluate them with the purpose of getting the sharpest filter as possible and also know which one is more efficient in this task. In order to achieve this purpose we designed, simulated and tried to manufacture the same low-pass filter (using microstrip lines) in different software. READ MORE

7. Studying Noise Contributions in Nonlinear Vector Network Analyzer (NVNA) Measurements
University essay from Avdelningen för elektronik, matematik och naturvetenskapAbstract : Noise contribution in nonlinear systems is very different from that in linear systems. The noise effects in nonlinear systems can be complicated and not obvious to predict. In this thesis, the focus was on the noise contribution in nonlinear systems when measuring with the nonlinear vector network analyzer (NVNA). READ MORE

8. Characterize the ZGST test bed
University essay from Akademin för teknik och miljöAbstract : Nyquist Shannon theory states that sampling rate of ADC should be at least twice of signal bandwidth in order to avoid aliasing. According to this theory, extracting an accurate behavior model of power amplifier by digitizing its output signal is a difficult task for current general ADC in the market, due to the trade off among the sampling rate, resolution and reasonable cost.

9. Analysis and verification of routing effects on signal integrity for high-speed digital stripline interconnects in multi-layer PCB designs
University essay from Institutionen för systemteknik; Tekniska högskolanAbstract : The way printed circuit board interconnects for high-speed digital signals are designed ultimately determines the performance that can be achieved for a certain interface, thus having a profound impact on whether the complete communication channel will comply with the desired standard specification or not. Good understanding and methods for anticipating and verifying this behaviour through computer simulations and practical measurements are therefore essential. READ MORE

10. Multidimensional Measurements : on RF Power Amplifiers
University essay from Institutionen för teknik och byggd miljöAbstract : Abstract In this thesis, a measurement system was set to perform comprehensive measurements on RF power amplifiers. Data obtained from the measurements is then processed mathematically to obtain three dimensional graphs of the basic parameters affected or generated by nonlinearities of the amplifier i.e. gain, efficiency and distortion.
