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

Our 2" base station duplexers are ideal for compact high isolation installations. These filters are designed for the combination of two frequencies that require extra isolation, or they can be used as efficient preselectors. Selectivity can be determined by the field adjustable capacitors. Each cavity is temperature compensated for operation between -40ºC to +60 ºC. Each cavity has a gold Alodine finish, silver-plated loops, and silver-plated tuning rods. -

Our Control Station Combiners (CSC) is an ideal solution to reduce the number of antennas required on a communications site by maintaining a high radio-to-radio isolation at all times. It can significantly reduce tower clutter and loading, and simplify cabling installation at control center facilities. This product provides frequency-agile operation across a frequency range from 380 up to 512 MHz. This combiner has the possibilities to be connected to two antennas TX and RX. In case of only one antenna is used for TX and RX, an external duplexer is required. DOWNLOAD PDF
