Next Webcast: RF Components for Aerospace & Defense

Wednesday, March 31st, 2010

The 2010 Webinar series from Microwave Journal and Besser Associates continues with a tutorial on RF Components for Aerospace & Defense Markets by instructor Bob Froelich.

This webinar will explain the fundamental characteristics of modern microwave radar and electronic warfare systems used by the world’s military and aerospace industries. It will provide an understanding of system performance and the microwave equipment that makes this performance possible.

Topics covered include:

  • Defense vs. Commercial philosophy
  • Standards and standards organizations
  • Quality assurance in defense
  • Military microelectronics
  • The difference in space
  • Microwave areas in defense: Radar systems, EW systems

Power Amplifier Tutorial

Wednesday, March 31st, 2010

The main characteristic of a Power Amplifier is that the design is focused on high linear output power. Gain in the transistor is generally sacrificed in the name of a higher 1dB compression point. This leads us to examine the three possible objectives when designing an RF amplifier: high gain, low noise figure, or high output power. (more…)

Featured Course: Applied RF II – Advanced Microwave and Wireless Techniques

Tuesday, March 2nd, 2010

This five-day course provides participants with an in-depth examination of advanced RF and microwave design techniques. Antennas and filters are covered briefly, followed by a detailed discussion of figures of merit. Mixers and oscillator designs are also evaluated. Considerable attention is devoted to defining, classifying, and improving the efficiency and linearity of power amplifiers. Numerous design examples are provided for participant exploration.

Upon completing the course, the participant will be able to:

• Select optimum receiver architectures.
• Describe the practical limitations of small antennas and filters.
• Detect hot spots in proposed designs.
• Use figures of merit to optimize new designs and available integrated circuits.
• Evaluate spurious responses.
• Evaluate tradeoffs between noise figure, IIP3, match, isolation and DC power.
• Design low noise and highly linear amplifiers.
• Design passive and active mixers.
• Explain and design VCOs and stable oscillators.
• Design low distortion and efficient power amplifiers.
• Utilize modern circuit simulators and a simple system simulator.
