50W Internal UHF Duplexers

Compact Single-Antenna Solutions for UHF Repeaters

The Icom IASDUP1036/37/38 series consists of professional-grade 6-cavity internal duplexers designed for high-performance UHF repeater systems. These specialized RF components allow a repeater to transmit and receive simultaneously through a single antenna port, eliminating the need for dual antennas or bulky external hardware. Specifically engineered to fit within the chassis of the FR6000 and CY6300 series, these duplexers provide a clean, integrated solution for space-constrained rack environments and mobile command centers.

With a power rating of 50 Watts and a 6-cavity design, these units provide excellent isolation between the transmit and receive paths, preventing receiver desensitization and ensuring clear audio. Each variant is optimized for a specific portion of the UHF band, providing reliable coverage across commercial, industrial, and public safety frequencies. With a standard 5MHz TX-RX separation, these duplexers offer a versatile and efficient migration path for single-site or networked repeater systems.

Key Features & Benefits

• Internal Chassis Integration: Designed for a factory-style fit inside the repeater, protecting the RF signal path and saving valuable 19-inch rack space.
• Single Antenna Efficiency: Enables full-duplex operation on one antenna, significantly reducing tower equipment costs and installation complexity.
• High-Isolation 6-Cavity Design: Provides superior rejection of transmitter noise to maintain maximum receiver sensitivity.
• Vibration-Resistant Build: Rugged construction ensures stable frequency performance in both fixed station and transportable deployments.
• Broad UHF Coverage: Multiple variants available to cover the full UHF spectrum from 400MHz up to 490MHz.
• Low Insertion Loss: Engineered to maintain maximum signal strength for both incoming and outgoing transmissions.

Frequently Asked Questions

• Are these duplexers pre-tuned? No. Duplexers must be tuned to your specific FCC-assigned TX and RX frequencies. It is recommended that a qualified technician perform the tuning using a calibrated network analyzer before installation.
• What is the benefit of an internal duplexer? It creates a highly portable, "one-box" repeater solution that is easier to deploy in the field and requires less rack space.
