Abstract :
The RF power at approximately 300 GHz coupled to a 52- Omega load by a one-dimensional DC series biased Josephson junction array has been measured using an on-chip Josephson detector. The array was fabricated using the planarized all-refractory technology for low-T/sub c/ superconductivity (PARTS). From the measured RF power and DC voltage levels, it is concluded that the 100 junctions in this array were locked in-phase. The effects of the finite inductance, associated with the junction´s shunt resistor, on the array output power and detector´s current-voltage characteristics are also discussed.<>
