General Notes:
1. Units in the IVM-20B series of I&Q networks are
composed of a 90° quadrature hybrid, an inphase power
combiner and two mixers feeding matched diplexers and
wideband video amplifiers.
2. Their function is to provide stable demodulated outputs
from a low impedance at a level suitable for processing.
3. Similar Quadraphase Demodulators are available with
30% and octave bandwidths and at frequencies up to 4
GHz in a different package.
4. Merrimac I&Q networks comply with the relevant
sections of MIL-M-28837 and may be supplied screened
for compliance with additional specifications for military
and space applications requiring the highest reliability.
NOTES:
