CH Series Standard Cavity Bandpass Filter Overview The CH series filter cover a frequency range from 30 MHz to 3,000 MHz. Percent 3 dB bandwidth ranges from 0.2% to 3%. The CH series uses a helical coil design to achieve lower frequency operation. Units are available with two through six sections providing a Chebyshev response with low insertion loss. VSWR is less than 1.5:1. Each unit is housed in a high "Q" sturdy aluminum case. Cavities are iris coupled and shielded to minimize RF leakage.
