100W UHF Power Amplifier

High-Power Signal Boosting for Mission-Critical Repeaters

The Icom IASPA550 is a professional-grade RF power amplifier designed to significantly extend the transmission range and signal strength of UHF base stations and repeaters. Engineered to deliver a robust 100 Watts of RF output from a low-level input of just 2 to 5 Watts, this amplifier is the ideal solution for large-scale industrial sites, wide-area security networks, and high-tier commercial installations. By boosting the signal at the source, the IASPA550 ensures reliable, clear communication across challenging terrain and through dense building structures.

Housed in a rugged 4RU (4 Rack Unit) chassis, the Icom IASPA550 is built for continuous-duty environments where thermal management and reliability are paramount. Its 19-inch rack-mountable design allows for seamless integration into standard equipment racks alongside the Icom CY6300 and FR6300 series. With high-performance cooling and industrial-standard RF shielding, this power amplifier provides the mechanical and electrical stability required for 24/7 mission-critical infrastructure.

Key Features & Benefits

• Powerful 100W Output: Provides a significant increase in effective radiated power (ERP), ensuring your signal reaches the farthest boundaries of your coverage area.
• Efficient Low-Drive Input: Specifically tuned for an input range of 2–5W, making it perfectly compatible with the low-power output modes of Icom digital repeaters.
• Industrial Cooling System: Features advanced thermal dissipation to maintain a high duty cycle during periods of heavy voice or data traffic.
• Standard Rack Integration: The 4RU chassis fits into any standard 19-inch equipment rack, simplifying installation and cable management.
• Mission-Critical Reliability: Engineered to meet the demands of security and industrial sectors that require uninterrupted communication.
• Enhanced Signal Penetration: Stronger RF output allows for better penetration in indoor environments and urban canyons.

Frequently Asked Questions

• Can I use this with a 25W or 50W input? No. The Icom IASPA550 is specifically designed for a low-power drive of 2–5 Watts. Using a higher input drive can damage the amplifier's internal circuitry.
• Does this require a separate power supply? Yes. A high-wattage 13.8V DC power source is required to support the 100W output, typically handled by an external DC distribution system.
• Is this compatible with IDAS digital mode? Absolutely. The amplifier is designed to maintain signal linearity, making it fully compatible with both IDAS (NXDN) digital and traditional analog FM transmissions.
