TTE Introduces RF & Microwave Filters Available from Stock



Lowpass Chebyshev “LC9S” Series Addresses Market Need for Off-the-Shelf Convenience



Los Angeles, CA (USA) – TTE Filters, a US-based manufacturer of high-reliability RF filters and microwave filters for demanding communication and signal processing applications, announced the introduction of a stocked Lowpass Chebyshev passive filter series – LC9S – providing off-the-shelf convenience and immediate delivery. The series was featured at the 84th Microwave Measurement Conference in Boulder, Colorado earlier this month. 



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-orer 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 availability – 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.
