Bandwidths may be specified from 2% to 20% of center frequency. The filter scan can handle up to one Watt (CW) of RF power. Standard versions are for 2%, 5%, and 10% passband bandwidth.The design ripple is typically 0.1 dB with a Chebychev response. High out-of-band rejection is offered with customer-specific attenuation characteristics.
