General Notes:
1. The QH-7 Series consists of multi-octave models with bandwidth ratios
ranging from 16:1 to 125:1. Their function is to split an input signal into two
equal amplitude, isolated outputs having a quadrature phase relationship.
Conversely, these units may be used to combine two quadrature phased,
equal amplitude signals into a single output.
