12.4-18.0GHz WR-137 WAVEGUIDE LOAD

• Broadband operation
• Low VSWR (Voltage Standing Wave Ratio)
• Protection of sensitive transmitter components

• Absorption of Microwave Energy:
  A WAVEGUIDE LOAD converts electromagnetic wave energy into heat, preventing standing waves. Any high‑power system requires a WAVEGUIDE LOAD to terminate unused ports.

• Reduction of Voltage Standing Wave Ratio (VSWR):
  By absorbing nearly all incident power, a WAVEGUIDE LOAD maintains a low VSWR (typically <1.05), ensuring signal source stability and measurement accuracy.

• Protection of Sensitive Components:
  During transmitter testing or amplifier tuning, a WAVEGUIDE LOAD acts as a dummy antenna. Without a WAVEGUIDE LOAD, reflected power could destroy expensive devices such as magnetrons or solid‑state amplifiers.
