WCA Series

Fixed/Stationary Waveguide -to- Coax Adaptors

MFC offers a large selection of fixed/stationary Waveguide-to-Coaxial adaptors. The WCA series of adaptors are used to transition from coaxial (TEM) mode to the dominant waveguide (TE10) mode.

WCA Series Waveguide-to-Coax adaptors utilize sturdy copper construction. This combines long service life with the lowest possible insertion loss for a device of this type. If weight is an issue, WCA series adaptors can be built using 6061-T6 aluminum.

Used for applications requiring good VSWR characteristics over the entire waveguide band, WCA series adaptors are available with 1.25:1 VSWR over the operating band of the waveguide.

FEATURES:
• Rugged Copper construction standard
(Aluminum available)
• Low VSWR (1.25 max)
• High power custom units available
