- A broadband magic-T based on double-sided parallel-strip line (DSPSL) and microstrip-coplanar waveguide (CPW) transition is presented and demonstrated. The DSPSL magic-T has broad bandwidth and low phase imbalance at the sum (H) and difference (E) ports. The equivalent circuits of the proposed multilayer circuit magic-T and transition between microstrip and CPW are derived. The experimental results show that the 4GHz magic-T provides more than 68% of 1dB operating bandwidth with the average in-band insertion loss of less than 0.7dB. It also has phase and amplitude imbalance of less than 4øand 0.65 dB, respectively. This magic-T was designed as DSPLS difference inputting of port E and two sides microstrip circuit outputting of port 2 and 3, and its structure is suitable for multilayer microwave integration circuit, especially LTCC multilayer circuit.
