Description

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 35 dB or greater rejection at the 2nd harmonic and greater than 40 dB to the 3rd 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.
