Multiplexers

Flight Microwave has experienced Output Multiplexer designers and tuners that produce superior performance from UHF to Ka Band. The multiplexer design and layout is custom tailored to meet the needs of the payload. These multiplexers may be delivered as a standalone unit or as a unit integrated with ancillaries such as Receive Reject, Harmonic filtering, test couplers and switches. Analysis (Mechanical, Thermal and Power Handling) is performed at FMC with results provided per customer SDRL requirements. Flight has the experience and facilities to provide testing is required for multipactor, corona or PIM.

High Power Ka Band Omuxes

Multiplexers
FMC has a line of multiplexers at K Band (Ka Band) the use an ultra high Qu resonator to provide the lowest output loss possible. This line supplements existing 18 to 21 GHz output multiplexers using more traditional resonators including TE11x and TE101 modes (WR51 waveguide). FMC has produced several types of multiplexers both herringbone or comb-line configuration, with on-orbit heritage including both temperature stable versions using Invar and wide passband filters where temperature stability is less important.These multiplexers have been used with up to 260 Watts per channel without multipactor breakdown

  • Very low loss high Qu channel filters
  • Qualified up to 200W/ Channel
  • Integrated high power isolator
  • Harmonic filters
  • Diplexer/ Triplexer
  • Multiplexers up to 8 channels

Ku Band Temperature compensated Omux channel

Multiplexer
These multiplexers are lightweight aluminum with thermally stable manifolds. Both odd/even and contiguous muxes designed. Non-monotonic as well as monotonic channel schemes available.

 

  • Light weight Aluminum filters
  • TE114 and TE113 dual mode cavity

S Band, L-Band Rx Tx Antenna Diplexers

Diplexer
These diplexers and filters are typically used in Antenna Arrays and Antenna Feed assemblies. FMC has a product line of low mass, low loss, low PIM devices for use on the payload antenna. FMC’s unique resonator configuration enables a very compact, light weight structure.
