Low-noise Josephson mixers at 115 GHz using recyclable point contactsThermally recyclable Nb point-contact Josephson junctions are investigated as low-noise mixers with an external local oscillator at 115 GHz. The best single sideband mixer noise temperature achieved is 140 (+ or - 20) K with a single sideband conversion loss of 2.4 (+ or - 0.5) dB. Such rugged junctions are suitable for use in practical receivers and should give unprecedented sensitivity at the shorter millimeter wavelengths.
