| Abstract: | Based on X-band signal sources, a 320-356GHz 9×2×2 solid-state multiply chain is realized with output power of
1-2mW. Using this source as local oscillator to pump the 664GHz second harmonic mixer, the DC bias is applied in the mixer to
lower the requirement of pumping power and noise temperature. The simulated results shows that, to the mixing diodes, with
pumping power of 0.3mW and DC bias of 0.35V, the SSB conversion loss of the mixer is lower than 12dB in 650-680GHz
frequency band, and the lowest is 10.8dB at 666GHz. |
