The Lowpass Chebyshev LC9S Passive Filter Series Addresses the Need for Off-The-Shelf Convenience

TTE has been manufacturing filters in the USA since 1956 and has particular expertise in short lead times.  Expedited lead time as short as 3-5 days is available on many built-to-order filter designs.  TTE’s new LC9S is a high quality filter series offered from inventory with competitive pricing and same day shipment.  This series addresses the market need of customers requiring immediate delivery – when 3 to 5 days is not fast enough.

The 9-pole filters in the LC9S Series deliver fast roll-off, an insertion loss of 1.0dB maximum and 50 Ohm terminations.  Nine part numbers are available, each at a specific -1dBc passband frequency, from 30 MHz to 3 GHz.

The series offers stopband attenuation of -40dBc at 1.5:1 ratio (rejection frequency from 45 MHz to 4.5 GHz) and -60dBc at 2:1 ratio (rejection frequency from 60 MHz to 6 GHz). Depending on frequency, the filters have input power of 5 or 10 watts max and utilize one of two SMA female connectorized cases. Operating temperature is 0°C to +70°C. RoHS compliant parts are available.

LC9S filters are designed for use in cellular, data acquisition, electronic support, radar, satellite, sonar, telecommunication, telemetry and wireless applications in commercial, industrial, medical and military/defense environments.
