Abstract :
This paper presents results for mm-wave coplanar waveguide couplers and a low loss slotline transition that are printed on polished beryllium oxide (BeO). BeO offers excellent microwave properties including a low loss tangent (0.0003) and high thermal conductivity. Included is the design of an optimized quadrature coupler with insertion loss around /spl sim/3.7 dB at 60 GHz.
