M.E.C.’s K600-147 is a K-band (WR42) orthogonal feed.  The design features a 3 dB sidewall hybrid at the input, two magic tees with integral loads, and waveguide plumbing.  It uses cast bends for very tight bend radii.  The assembly is fabricated from copper to minimize losses.  This compact and mechanically rigid design covers a band of 20.2 – 21.2 GHz and has low insertion loss, along with good amplitude and phase tracking.
