Flight Microwave was founded by the engineers and managers that formerly designed the Passive Microwave Hardware for Hughes Space and Communications, HSC.

This group was responsible for the majority of patents and unique passive designs that distinguished HSC as the leader in Multiplexer design. This team was not part of the transfer to Torrance and eventual sale to L3 com.

Since 1981, this group has designed and produced complex filter hardware ranging from dielectric Input Multiplexers, to Antenna Array Diplexers, to 18 ch output Multiplexers. The expertise covers the full range from UHF to 60 GHz.
