Description

MEC Rectangular Waveguide Standard Length 80-L, Ultra-short 80-LU, Communications and Narrow Band 80-LA Terminations consist of precision aluminum waveguide containing rugged material especially selected and designed to absorb incident power with very low reflection.

These units are idea for laboratory and field measurements and production setups requiring high quality terminations. Additional features are short length and light weight. Typical applications include VSWR measurement of waveguide components, low power dummy antennas and matched terminations for directional couplers, hybrids and other devices.

All units have a Chemical Film finish per MIL-C-5541, Class 3, followed by gray epoxy enamel. A power sampling probe can be supplied as a separate unit with any of the terminations. Typical flatness is ± 0.5dB across the entire band for sampling levels from 30 to 50 dB.

ORDERING INFORMATION                                                                *Aluminum

  1. For Power Sampling, add suffix "PS" to model number and specify sampling level (from 30 to 50 dB) desired.
  2. Half-height terminations, other frequency ranges, and unique mounting arrangements also available.
  3. 80-LU Series also available from 2.6 through 50 GHz with smaller bandwidth and improved VSWR. Add suffix "L", "M", or"H" for low, middle, or high half of band.
