Device Topology & Electromagnetic Behavior
A precision thin-film resistor terminating an RF transmission line into a perfect 50.0 Ω match referenced to ground. Absorbs 100% of incident electromagnetic energy with no reflected wave (return loss > 35 dB). Indispensable for circulator dump ports, hybrid coupler isolated ports, and high-power amplifier transmitter test loads.
Beryllium Oxide (BeO) or Aluminum Nitride (AlN) high thermal conductivity substrate mounted to copper flange.
- Direct low-inductance grounding via arrays directly at the resistor edge.
- High thermal-conductivity silver solder mounting to solid chassis heat spreader.
