That is why demanding television broadcast markets both in the US and around the world turn to us for their digital VHF television filtering and channel and power combining needs. High Band VHF Band Pass Filters ERI’s high band VHF band pass filters are band tunable designs available in 6 and 8 section versions in both reflective and constant impedance configurations. Standard model designs are available to handle one to 10 kilowatts. High Band VHF Low Pass Harmonic Filters ERI offers a series of high rejection, low-pass harmonic filters for transmitter power levels up to 45 kW for high band VHF applications. Chebyshev design parameters define element values which, when synthesized, provide 40 dB or greater rejection at the 2nd harmonic and greater than 50 dB to the 5th harmonic. The oversized center section ensures optimal power handling capability. Each filter is individually tested and tuned for optimum electrical and mechanical performance. Measured test data is supplied with each filter. High Band VHF Power Combiners and Hybrids ERI manufactures a wide variety of switching and switchless power combiners for High Band VHF television applications. The all systems include the ability to bypass the combiner and put a single cabinet on-air for periodic maintenance and emergency operation. The company also manufactures hybrid splitters and combiners as well as patch panel switching systems. Contact ERI for special configurations. Low Band VHF Band Pass Filters ERI offers a full suite of products for Low Band VHF applications. These include reflective and constant impedance band pass filters, low pass harmonic filters, and the accessory RF components required to produce complete systems. In addition to providing filter sets for spurious emissions compliance ERI also can provide filter sets for channel combining. Low Band VHF Low-Pass Harmonic Filters ERI offers a series of high rejection, low-pass harmonic filters for transmitter power levels up to 45 kW for low band VHF applications. Chebyshev design parameters define element values which, when synthesized, provide 40 dB or greater rejection at the 2nd harmonic and greater than 30 dB to the 5th harmonic. The oversized center section ensures optimal power handling capability. Each filter is individually tested and tuned for optimum electrical and mechanical performance. Measured test data is supplied with each filter.
