Icom IASDUP1010

High-Power 6-Cavity VHF Duplexer

Reliable Single-Antenna Performance for High-Duty Repeaters

The Icom IASDUP1010 is a professional-grade 6-cavity duplexer designed for high-performance VHF repeater systems. Operating within the 144-190MHz frequency range, this heavy-duty component allows a repeater to transmit and receive simultaneously through a single antenna. By providing exceptional isolation between the transmitter and receiver, it prevents signal interference and receiver desensitization, ensuring clear and reliable communication even in RF-congested environments.

Engineered for durability and power, the Icom IASDUP1010 supports up to 100 Watts of continuous power, making it the ideal choice for high-power base stations and repeaters like the Icom CY series. With a minimum TX-RX separation requirement of only 3MHz, this duplexer offers significant flexibility for frequency planning. Equipped with precision N-Female connectors, it ensures a secure, low-loss connection to your RF infrastructure.

Key Features & Benefits

High Power Handling: Rated for up to 100W, allowing for high-power repeater deployments without the risk of thermal drift or component failure.
6-Cavity Design: Provides superior selectivity and deep notch rejection to isolate the sensitive receiver from the high-power transmitter.
Narrow Frequency Separation: Capable of maintaining high performance with a minimum TX-RX spacing of just 3MHz.
Wide VHF Coverage: Operates across the 144-190MHz band, covering amateur, commercial, and public safety VHF frequencies.
Single Antenna Efficiency: Eliminates the need for dual antennas, reducing tower space requirements and lowering overall installation costs.
Rugged Construction: Built to withstand the environmental and electrical demands of 24/7 mission-critical repeater sites.

Frequently Asked Questions

Does this duplexer come pre-tuned? Duplexers must be tuned to your specific FCC-assigned frequencies. It is recommended that a qualified RF technician perform the tuning using a calibrated network analyzer.
Can this be used with the FR5300? Yes, while specifically listed for the CY series, this 100W duplexer is compatible with any VHF repeater system requiring high-power isolation within its frequency range.
What is the benefit of a 6-cavity design over a 4-cavity? A 6-cavity design provides much higher isolation and steeper filter skirts, which is necessary when the TX and RX frequencies are close together or in high-interference areas.
