1. EECTECH microwave provides a series of standard waveguide pressure windows with frequencies ranging from 0.3 to 110 GHz and standard rectangular waveguides ranging from BJ3 to BJ900.


2. EECTECH microwave has a series of high performance waveguide flange gaskets, which are suitable for rectangular waveguide, flat rectangle, medium flat rectangle, square, circular, single ridge and double ridge standard type, etc. Frequency ranges from 0.3 to 110 GHz. The standard rectangular waveguide ranges from BJ3 to BJ900. The typical VSWR is 1.03 on the whole waveguide bandwidth and the typical insertion loss is 0.1 dB.
