Abstract

We demonstrate a decade-passband superconducting diplexer operating from dc to 27 GHz, integrated in a niobium, Josephson-junction(JJ)-compatible process. Both low- and high-pass branches are singly-terminated 5-pole Butter-worth filters with a 2.5 GHz cutoff. Several fabricated three-port diplexers are characterized with on-wafer cryogenic two-port calibration, and an insertion loss of 1 dB is measured across the entire frequency range. Although measurements are performed up to 27 GHz, the simulated upper diplexer band extends to 40 GHz, a record four-octave bandwidth. This device is useful when integrated in large-scale superconducting JJ-based quantum processors, broadband sensors, amplifiers and sources.
