P09343 Microwave Devices II Test Plans & Test Results 1. MSD I: PRELIMINARY TEST PLAN 1.1. Introduction and Overview 1.1.1. Project Background. This project is the second project with Anaren Microwave Inc. The previous project during the 2007-2008 school year designed, simulated, built and tested a modified Wilkinson power divider. This project will design two 4x4 X-Band Butler Matrices used for antenna beamforming. 1.1.2. Project Testing Overview. There will be two different layouts explored through this project incorporating four subsystems. The subsystems are a 180 hybrid coupler (Knöchel model), a 90 hybrid coupler (Branchline), a 45 phase shifter (Schiffman) and a connector launch. Each system as well as the individual components will be tested, and their performance evaluated based on the expected results from simulations. 1.2.

Calibrate the network analyzer for a frequency range of 9GHz to 14GHz. 2. For each system, connect Port 1 as an input and Port 2 as an output on the network analyzer. 3. Collect the N-port data in magnitude/phase format, making sure that magnitude is in db and the phase is in degrees, for that particular input/output combination. 4. Repeat the procedure for all input/output combinations (16 total combinations). 5. For each component, connect Port 1 as an input and Port 2 as an output on the network analyzer. 6. Collect N-port data in magnitude/phase format for each possible input/output combination, where possible. 7. Using MATLAB, extract the collected N-port data and plot the desired results. o Plot output magnitude of each input and all output combinations. o Plot phase error for all combinations. o Plot transmission error. o Plot return loss. o Plot phase progression. 8. Analyze the results, and determine if the components and system fall within pass/fail criteria. 9. Using HFSS and Designer, determine possible improvements to the components and systems, and show using simulations that observed errors may be corrected. 1.5. Definitions; Important Terminology; Key Words Return loss reflection of signal power resulting from the insertion of a device in a transmission line, and is usually expressed as a ratio in db relative to the transmitted signal power.
