Topic- PHASE SHIFT OSCILLATOR
Question 1
A purely resistive load has a VSWR of 3 in a lossless transmission line. Given that the characteristic impedance is 50 ohm, find all possible values for the load impendence. Illustrate your answer using a Smith Chart.
Question 2
Design a bandpass filter with the following requirement:
a centre frequency of 2.4 GHz
XX MHz bandwidth where XX stands for the last 2 digits of your CU student ID
0.1 dB passband ripple
at least 20 dB stopband attenuation at 2.6 GHz
50 ohm impedance
You are required to design your filter manually (without using any design-aid software). Then, verify your design using ADS software and include any supporting materials for your design.
Question 3
Write a review on a type of oscillator of your choosing.
The selected oscillator should not be about basic oscillators such as the LC,Colpitts or Hartley. Rather, it must be on a further developed or higher application stages of an oscillator. Important: Register your chosen oscillator in Blackboard to avoid having duplicates with other students.
The review must include the principle of operation and/or technical features of the oscillator. At least 5 main technical points must be discussed. This should also include any relevant graphs or illustrations.
Provide your own comment(s) on the oscillator. The comments should focus on the technical aspects or feasibility of the design based on your analysis.
Your citation must include at least 2 indexed publications rated by SCOPUS or Web of Science. These would be your main sources of information.
The review should be academic in nature.
The length of the summary should not exceed 750 words.
