1. Rectangular to Rectangular Waveguide, Adapters in Overlapping Bands
A-INFO's waveguide tapered transitions cover the frequency range up to 170 GHz in several waveguide bands. The tapered transitions allow very efficient propagation of RF energy from one waveguide size to another. Transitions are available in standard lengths as well as customer specific lengths.

2. Double Ridge to Rectangular
These precisely machined transitions allow connection of double-ridge waveguides to rectangular waveguides or other ridge guides with low insertion loss and good match. These transitions are most suitable for laboratory set-ups to measure double-ridge components with rectangular waveguide test equipment and vice versa.
The attached table ONLY lists the transition model numbers and lengths for overlapping bands. For over-moded transformers, which is available up to the second and third harmonic of the double-ridge fundamental frequency band, please consult A-INFO for details. Other lengths, bands and types may also be requested.
