Tasks

• Ricardo Simulated one arm of the switch and
  found an error
• with the length of the microstrip line.
• Tam Simulated multiple arms of the switch with
  the
• correct microstrip length.
• Paul Began correcting the PCB layout which
  will be
• re-submitted to PCB Express.
• Sean Worked on final report

Summary
Accomplished Goals

• Corrected length of microstrips to be used on
  PCB layout.
• Received PCB board.

Goals\Tasks for Week 10

• Solder parts (resistors, inductors, capacitors,
  diodes) to PCB board.
• Test and revise PCB board at Hughes Network
  Systems laboratory.
