Modeling Of Large Microwave Cavities For Industrial And Scientific Applications By CST of America, Inc.
Simulating microwave cavities can prove to be difficult. The size of the cavity itself, the resonant nature of the cavity, and the number of total modes can all contribute to issues in microwave cavity modeling. This white paper discusses the modeling of microwave cavities and demonstrates how a system for heating test samples was optimized using electromagnetic simulation.

This report quantifies the performance of XFdtd’s GPU and MPI technologies, including hardware comparisons of speed vs. cost. By running approximately 160 simulations on NVIDIA’s PSG Cluster, we demonstrate the pros and cons of different combinations of equipment and techniques, including cost considerations for those researching available hardware.
The dB-4127 is a microwave power module operating in the 6 to 18 GHz frequency range. This MPM is a power amplifier that provides 200 Watts pulsed/CW RF output power. The RF signal path consists of a solid state amplifier and a vacuum power booster.
The model 845-HP microwave signal generator was developed based on customer feedback requesting higher power in Berkeley Nucleonics’ line of signal generators. The 845-HP covers the 100 kHz to 20 GHz frequency range and has an up to +23 DBM output power range.
API Technologies’ TEMline series of 3 dB hybrid couplers have an average power rating of 1000 W and are normalized at 1 GHz. They also feature 1-dB maximum unbalance and 90 degree phase differential between outputs. Designed to meet MIL-E-5400 Class 3 and screenable to MIL-P-23971, these couplers are ideal for telecommunications and radar applications.
