AB  - The prototype of a waveguide balanced Hot Electron Bolometer (HEB) Terahertz mixer is designed as a part of development for the APEX Project of Band T2 receiver for 1250-1390 GHz. The proposed mixer employs balanced scheme with two identical HEB devices. These individual mixers would be placed on two separate crystalline quartz substrates  with  dimensions  of  1000μm  x67μm  x17  μm  each  with  integrated  RF  choke  filters,  DC-bias  and  IF  circuitry. A 3 dB quadrature waveguide directional coupler is needed to provide local oscillator (LO) injection and RF  signal  distribution  between  the  two  HEB  mixers.  We  have  designed  the  coupler  to  achieve  the  required  frequency  band,  low  insertion  loss  and  symmetrical  division  of  the  RF  and  LO  power  within  the  band  of  interest.  Initial  design  of  HEB  mixer  layout  is  developed  based  on  a  previous  development  for  a  345  GHz  sideband  separation  mixer.  We  present  also  results  of  development  of  microfabrication  technology  of  the  waveguide  hybrid  employing micromachining approach combined with electroplating technique.
