The "MultiStep" Advantage
Traditional couplers often require precise, frequency-specific tuning to achieve acceptable VSWR and isolation. COM-TECH’s MultiStep Technology revolutionizes this by using a stepped-impedance design structure.
- Ultra-Broadband: Operates across wide frequency ranges (e.g., full FM band 87.5–108 MHz or UHF) without manual retuning.
- Stability: Eliminates the drift associated with tuned LC circuits.
- High Power Handling: Engineered with robust aluminum bodies and PTFE insulators to handle high RF power levels reliably.
Product Categories
1. Hybrid Couplers (3dB / 90°)
COM-TECH Hybrid Couplers are the industry standard for combining two transmitters or creating balanced power splits. These 3dB, 90-degree quadrature hybrids are essential building blocks for Double Bridge Combiners and variable power splitters.
- Key Application: Combining two transmitters of equal power into a single output, or splitting one transmitter to feed two antenna systems with a 90° phase shift.
- Specs: Available in connector sizes from 7/16 DIN up to 3-1/8" EIA, handling power levels up to 19kW+.
- Isolation: Typical channel isolation >28 dB, protecting your transmitters from reverse power.
2. Multicouplers (Signal Distribution)
When you need to distribute RF signals to multiple destinations—such as monitoring ports, exciter feeds, or receiver arrays—COM-TECH Multicouplers provide a compact, low-loss solution.
- Configurations: Available in starpoint or manifold configurations depending on the number of ports required.
- Impedance: Strictly matched 50-ohm characteristic impedance to maintain system VSWR.
3. RF Splitters & Dividers
For antenna array feed systems, COM-TECH Power Splitters ensure that RF energy is divided accurately to maintain the correct pattern and gain.
- Precision Splitting: Equal or unequal power division options available.
- Rugged Design: Built to withstand the environmental conditions of transmitter sites.
