We present results on the design and construction of a waveguide balanced Hot Electron Bolometer (HEB) Terahertz mixer for Atacama Pathfinder EXperiment (APEX), band T2 covering 1250-1390 GHz frequency range. In the proposed design, a waveguide balanced mixer is realized using a quadrature scheme. The two identical HEB elements are integrated with RF choke filters, DC-bias, IF circuitry, and fabricated from 4 nm thick NbN film deposited on a crystalline quartz substrate with dimensions of 1100 μm×70 μm × 17 μm. We have designed and fabricated an input 3 dB quadrature waveguide hybrid. For its fabrication, we use micromachining approach to achieve low insertion loss and symmetrical division of the RF and local oscillator (LO) power within the band of interest. We plan to use two HEB mixer configurations with different probe impedance values of 55, 70 Ohm within 1250-1390 GHz frequency range.
