KRYTAR Announces New Compact 3 dB, 90-Degree ULTRA+ Hybrid Coupler Covers 2 to 18 GHz

Why It Matters

The ULTRA1830 delivers ultra‑wideband performance in a small package, enabling designers to simplify RF front‑ends for 5G, defense, and satellite systems while reducing size, loss, and BOM complexity.

Key Takeaways

• 3 dB coupling across 2‑18 GHz
• ±0.3 dB amplitude imbalance
• ±4° phase imbalance
• >17 dB isolation, 1.35 VSWR
• 20 W avg, 3 kW peak power

Pulse Analysis

Hybrid couplers are essential building blocks in modern RF architectures, providing signal splitting, combining, and phase control. KRYTAR’s ULTRA1830 pushes the envelope by covering the entire S‑through‑Ku band with industry‑leading specifications, such as sub‑1.2 dB insertion loss and tight amplitude/phase balance. This breadth eliminates the need for multiple narrowband components, streamlining system design for high‑frequency applications like 5G NR, Wi‑Fi 6E, and satellite payloads.

The technical merits of the ULTRA1830 translate directly into performance gains for demanding use cases. In electronic warfare and radar, the >17 dB isolation and low VSWR ensure signal integrity under high‑power conditions, while the 20 W average and 3 kW peak ratings support power‑intensive transmitters. Its compact 2.85 × 1.10 × 0.52 in footprint and lightweight construction make it ideal for space‑constrained platforms, from airborne arrays to handheld test equipment, without sacrificing the tight coupling needed for precise beam‑forming and MIMO operations.

From a business perspective, KRYTAR’s rapid‑to‑stock availability (30‑day ARO) and compliance with military standards position the ULTRA1830 as a strategic component for both commercial and defense suppliers. The ability to source a single, ultra‑wideband coupler reduces inventory complexity and lowers total cost of ownership, a compelling advantage as the industry accelerates toward 6G and higher‑frequency deployments. As networks demand broader bandwidths and tighter integration, components like the ULTRA1830 will become critical enablers of next‑generation connectivity and sensing solutions.
