Description
Icom UHF Internal Duplexers 5MHz Separation
IASDUP1036 / IASDUP1037 / IASDUP1038
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
-

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.
