Broadband LTCC transition from coaxial connector to stripline for 60GHz application
A new coaxial-to-stripline transition based on low temperature co-fired ceramic (LTCC) is proposed and experimentally verified. An additional multilayer dielectric cavity is embedded in the LTCC substrate to improve the impedance and field matching and therefore achieve a wide bandwidth. The measurement results for a back-to-back structure show an a return loss better than 10 dB up to 67GHz.
