Novel Artificial Transmission Line Approach for Synthesis of MMICs for MMW Communications

A novel error parameter analysis approach for synthesis of an artificial transmission line (ATL) from the ABCD parameters of a uniform transmission line section is presented. An MMIC ATL delay line with 180deg phase shift is synthesized to demonstrate this approach. The MMIC is fabricated using a conventional GaAs process and test results are validated with those of the simulated results.
