An anti-parallel (AP) diode pair based on a Fermi-level managed barrier (FMB) diode was developed for the sub-harmonic mixing of terahertz waves. A quasi-optical module integrating an AP–FMB diode pair and a trans-impedance amplifier exhibited a very low noise-equivalent-power of 9 × 10−19 W/Hz at an input signal frequency of 304 GHz with a very low local oscillator power of 30 μW.
