The description sections and FAQ are machine-assisted and can contain errors; where they disagree with the record, the record is correct, and where description sections disagree with each other, Details wins._ ## Summary - Manufacturer: K&L Microwave - Model: 8IL41-127.6/U189.8-0/0 - Condition: Used and in Excellent Condition - Price: $110.00 USD - Availability: In stock, 2 available - Warranty: 1-Year Warranty with 30-Day Return Guarantee - ITAR restricted: No - Shipping weight: 2 lb, estimated - Shipping dimensions: 8X8X3 in, estimated ## Categories - Test Equipment > Electrical Test > Signal Conditioning (primary) ## Details ### Configuration - Number of Sections: 8 - Series: I-Microminiature - L-Lowpass - Package Designator: Style 4 - Cut-Off Frequency: 127.6 MHz - Supplemental Codes: One dB Bandwidth - Upper Frequency Stopband Limit: 189.8 MHz - Input Connector: SMA Female - Output Connector: SMA Female ## Function Provides high-rejection lowpass filtering of microwave signals within compact microminiature hardware; designed for insertion in microwave transmission lines to suppress harmonics and spurious frequencies above a specific cutoff frequency; interfaces through coaxial or waveguide connectors compatible with standard microwave test and communication equipment; serves in radar, communication, and signal conditioning systems requiring minimal insertion loss and compact size. ## Platform Provides sharp frequency cutoff at 127.6 MHz with ultimate rejection beyond 189.8 MHz for spurious signal suppression in RF and microwave systems. Features microminiature form factor enabling high-density circuit layouts in space-constrained environments. Interfaces through SMA connectors. Common applications include receiver front-ends, transmitter harmonic filtering, IF chain signal conditioning, and test instrumentation where precise frequency band limiting is required in communications, radar, and electronic warfare systems. ## Application Used in RF and microwave circuits to attenuate frequencies above a specified cutoff while allowing lower frequencies to pass; suitable for applications requiring high-performance filtering in compact spaces such as communication systems, electronic warfare, and test equipment. ## Images - - - -
