Filters & RF Components

DESIGNED FOR MAXIMUM PERFORMANCE AND EFFICIENCY
Our filters have been selected by some of the leading Public Safety organizations across North America to ensure Mission-Critical performance for their RF networks. Comprod manufactures each cavity filter in North America – skilled RF technicians, quality calibration, and insistence on high-quality plating materials. This ensures that the filter performance will be optimal, tuning can be easily performed by your technicians, and the RF signals remain as pure and clean as possible. Our customers notice the difference in quality and reliability.
• Four versions of filters available: Band-Pass, Notch, Pass-Reject, and X-Pass, available in 2″, 4″, 6.625″ and 10″ cavities
• 6.625” and 10” filters have two hand-movable tuning rods for faster tuning. Silver-plated adjustable coupling loops and a calibration index label help to facilitate setting the cavity insertion loss as required for each application.
• Combination of a heavy-gauge aluminum outer conductor, thick heliarc-welded cavity top plates, heavy silver-plating on micro-finished tuning assemblies, and Invar-based temperature compensation material for constant performance levels and long-term reliability
• Silver-plated brass bodies, gold- plated center contacts and thru-line cable assemblies that are made with high-quality connectors and RG-393B/U Teflon or RG-214/U cable to provide excellent intermodulation rejection at high system power levels
• Gold-plated cable connector center contacts are soldered to the cable and the dual shield is securely crimped to the connector barrel using pneumatic fixtures and precision dies

  • We offer a full line of Power Splitters. The 47-02-XXN and 47-35-XXN series is a hybrid design which provides 20 dB or more of port-to-port isolation. They are typically used on receiver multicoupler applications. They provide low loss above the splitting loss and cover a very wide frequency range. N connectors are standard but other connectors are available. Standard finish is gold Alodine. DOWNLOAD PDF
