Icom IASDUP1015

50W Internal VHF Duplexer

Compact Single-Antenna Solution for VHF Repeaters

The Icom IASDUP1015 is a professional-grade internal duplexer designed to provide seamless single-antenna operation for Icom VHF repeaters. This 6-cavity filtering component allows your repeater to transmit and receive simultaneously through a single antenna port, eliminating the need for two separate antennas or an external, space-consuming duplexer. Specifically engineered to fit within the chassis of the CY5300 and FR5300, it provides a clean, integrated solution for space-constrained installations.

Operating in the 152-175MHz range, the Icom IASDUP1015 supports a power output of up to 50 Watts, making it ideal for standard-duty commercial and public safety applications. Its 6-cavity design ensures high isolation between the transmit and receive paths, preventing interference and maximizing receiver sensitivity. With a minimum TX-RX separation requirement of 6-15MHz, this duplexer offers reliable RF performance for mid-to-high frequency spreads.

Key Features & Benefits

Internal Chassis Mounting: Designed to be installed directly inside the repeater housing, saving valuable rack space and protecting the duplexer from damage.
Single Antenna Efficiency: Allows for full-duplex operation on a single antenna, significantly reducing tower rental costs and simplifying cable runs.
6-Cavity Selectivity: Provides superior rejection of transmitter noise, ensuring the receiver remains sensitive even during high-power broadcasts.
Rugged RF Performance: Rated for up to 50W of continuous power, providing long-term reliability for professional VHF systems.
Standard N-Connectors: Equipped with high-quality N-connectors for low-loss signal transfer and industry-standard compatibility.
Optimized for Icom Hardware: Custom-designed for a perfect physical and electrical fit with the CY5300 and FR5300 series repeaters.

Frequently Asked Questions

Does this duplexer come pre-tuned? No. Duplexers must be tuned to your specific assigned TX and RX frequencies. It is recommended that this be performed by a qualified technician using a network analyzer before installation.
Can this be used with a 100W repeater? No. The Icom IASDUP1015 is rated for a maximum of 50 Watts. For 100W systems, a higher-rated external duplexer like the IASDUP1010 should be used.
What is the advantage of an internal duplexer? An internal duplexer creates a "one-box" solution, making the repeater much easier to transport and install in compact 19-inch racks or small enclosures.
