CR Datasheet, PDF (1/2 Pages) Littelfuse – The CR range of protectors are based on the proven technology of the T10 thyristor product

CR Series
Standard Cavity Bandpass Filter
Overview
The series CH and CR filters cover a frequency range from 30 MHz to 3,000 MHz. Percent 3 dB bandwidth ranges from 0.2% to 3%. The CR series uses 1 /4 wavelength
resonant structures while 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.
