Greetings from the 2017 International Microwave Symposium in Honolulu, Hawaii! This show is a great opportunity to re-connect with fellow RF and wireless professionals, learn about the latest design techniques, and see the newest products being offered at the exhibition. Besser Associates is here at booth #942. The show is always an opportunity to get new ideas and brainstorm for new courses and resources that we can offer on the RF Mentor site.
This workbook from the RF Technology Certification program demonstrates how to convert from dBm to milliwatts using approximation techniques without a calculator. An interactive calculator at the end demonstrates the process with values that you can enter yourself to practice.
I've successfully added transmission line elements to the Smith Chart matching web app here on RFMentor.com. These include series, shorted shunt section, and open shunt section. There's a trick you can use to have these transmission line elements use an arbitrary characteristic impedance. The elements adopt the same characteristic impedance as the chart normalization impedance (default is 50 Ohms).
This in-depth resource provides comprehensive coverage of femtocells and how they integrate with existing 3G and emerging wireless protocols and standards. Femtocells: Design & Application provides a technical roadmap for migrating to femtocell technology, covering network architecture, media protocols, system performance, and security issues. Detailed architectural diagrams illustrate various deployment options. This is a practical guide to the pioneering technology that enables extended indoor service coverage.
I created a quick Python function to calculate the component values for an impedance match between two real (resistive) terminations using the technique taught in the Introduction to Impedance Matching course. Here is what the code ends up looking like, and it shows how useful Python can be for working as a "quick programmable calculator." In the old days, I might have been tempted to program my old HP48 calculator to crank out the same values. It only took a few minutes to put the code together, which is the beauty of working with Python.
I created a brief video showing what an impedance matching network created using analytical techniques looks like on the Smith Chart. The impedance matching network was created in an exercise that is part of the Introduction to Impedance Matching course.
