Nine-pole lowpass Cheyshev filters in the LC9S series are available in nine models with different 1-dB passbands, from 30 MHz to 3 GHz. The maximum passband insertion loss is 1 dB with stopband attenuation of -40 dBc at a 1.50:1 ratio (rejection frequency to passband frequency) and -60 dBc at a 2.0: ratio. Employing SMA female connectors, these RoHS-compliant filters can handle power levels from 5 to 10 W. They are designed for operating temperatures from 0 to +70°C.
