UF7500/UF17500/UF25000 Series UHF Band Pass Filters Features: ATSC, DVB-T and ISDB-T Tunable from 470 to 608 MHz Tunable for 6, 7, or 8 MHz Channels Non-Critical and Critical Masks Temperature Compensated Optional Items: Fine-Matchers to optimize system performance Directional Couplers to monitor system performance Output Switching/Patching to test system performance Low Pass Harmonic Filters The UF7500/UF17500/UF25000 is a product family that shares a common case and handles up 7.5 kw average power when convection cooled. The power handling is increased to 17.5 kw, average power, with the addition of forced air cooling and to 25 kw with liquid cooling. The filter is tunable and exceptionally efficient. The filter is constructed of lightweight silverplated Aluminum with silver plated Aluminum resonators The Evanescent coupled TEM resonators are durable and provide a rugged design that tunes easily. Tuning elements are designed with the tuner in mind, allowing precise tuning for today s stringent applications in significantly less time for additional cost savings. Multiple cross couplings are provided to increase rejection of transmitter out of band emissions. Six and eight pole designs are available for 8-VSB and COFDM applications and listed below. Input and output connections are 3-1/8 or 4-1/16-inch, 50-ohm, unflanged.
