This proposal examines several methods for preventing shipboard SINCGARS transmitters from overdriving a cosite sensitive signal exploitation receiver. ZA proposes to pursue development of a novel proprietary multiplexer technology to achieve that objective which offers interference suppression greater than 30 dB, insertion loss less than 5 dB for signals of interest anywhere in the 30-88 MHz frequency range, and compact size to meet the 18 inch x 18 inch x 4 inch objective.
Benefit: Development of the proposed technique will allow a shipboard signal exploitation receiver to operate over the 30-88 MHz frequency range with no subbands desensitized by multiple, strong, cosited SINCGARS transmitters. The technique will also be beneficial to SINCGARS communications reception in the presence of strong cosite SINCGARS transmissions on U.S. Navy ships and on ground vehicles operated by the U.S. Marine Corps. and U.S. Army.
