* The electrical properties of flex/only core are essentially the same as for the flexible/twistable core, with the exception of the RFl leakage figure which is not applicable to flex/only core. A conductive silicone jacket is available for standard flexible/twistable waveguides, which guarantees RF leakage better than -90dB - insert the letter E in the jacket field of the TWS part number (eg FT 20PEB 403-402/M300)
** Insert flexible Waveguide length in mm
*** For 3 digit Rectangular Waveguide or Double Ridged Waveguide flange part number, refer to the TWS Flange catalogue, or consult the factory.
H = Half Height Waveguide

Notes

  1. RF Leakage specification based on the TWS method of test detailed in the data sheet.
  2. V.S.W.R. figures are based on Plain to Plain flanges. Degraded figures can be expected with Plain to Choke flanges.
  3. Power specifications are based on figures published in IEC 636 for complete jacketed assemblies and are the maximum recommended for the lowest frequency in the designated band.
  4. Peak power rating is calculated mid-band with a load match of 1.5:1, a power safety factor of 2.25 and assumes a voltage breakdown at NTP of 30,000V/cm.. Power ratings are for information only.
  5. The match of the waveguide can generally be optimised over a reduced frequency band. Please specify the operating band when ordering.

* Twisting Rating not applicable to flex/only core
Length of Flexible Twistable Assemblies
The overall length of waveguide assemblies, is measured as the distance between the front face of both flanges.
The maximum length of flexible and flexible twistable waveguide is dictated by the mechanical strength of the waveguide and the production tooling available.
The following is a list of the standard recommended length for the various waveguide sizes. Other lengths may be available on request but may be subject to tooling and design charges.
MM: 75, 150, 230, 300, 380, 460, 500, 600, 650, 760, 900, 1000, 1250 and 1500
INCHES: 12, 24, 36 and 48.
All lengths are subject to a tolerance on the length of 1.5% or 2mm or whichever is greater
