In this thesis, a thru-reflect-line (TRL) calibration technique enabling full S-parameter characterisation for membrane circuits has been demonstrated in the WR-03 waveguide band (220 to 325 GHz). The designed membrane TRL kit is packaged in E-plane split blocks. An improvement of beam lead to ground connection was utilized by recessing the block surface. The proposed calibration provides the reference planes right at device under tests, thus reduces an extra de-embedding step. Membrane circuits such as stub filter, thin film resistors, thin film capacitor were characterised by applying the presented method. The simulated and measured results agree well, showing the validity of this approach. Furth
