Input IMUX and Output OMUX Multiplexers

Lucix’s portfolio includes high performance state-of-the-art input and output multiplexers. Our expert designers and tuners produce unparalleled IMUX and OMUX multiplexers tailored to meet the needs of a great variety of payload architectures. Our multiplexers can be delivered as standalone units or integrated with an array of qualified ancillary hardware such as receive reject filters, harmonic filtering, test couplers and switches. Every unit undergoes thorough mechanical, thermal and power handling analysis and tests with results provided per customer SDRL requirements.

Our integrated output assemblies typically include:

• Integrated Output Assembly
• Super High Q Filters > 18000Q
• Temperature Compensated Filters
• Thermal Shift 25% of Invar
• 150W Per Channel

Lucix multiplexers at Ka Band 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).

Lucix has produced various types of multiplexers, both herringbone or comb-line configuration, with on-orbit heritage including temperature stable versions using Invar, wide passband filters, and temperature compensated filters. These multiplexers have been used with up to 260 Watts per channel without experiencing multipactor breakdown.

Lucix engineers pioneered temperature compensated Omuxes for direct to home broadcast in the 1980s. These multiplexers are lightweight aluminum with thermally stable manifolds. Both odd/even and contiguous muxes have been delivered with non-monotonic and monotonic channel schemes available. K/Ka Band OMUX channels feature:
