Listed at 225.95 USD. 10pcs Mini-Circuits XLF-173-DG+ Reflectionless Low Pass Filter Die, DC-17GHz, 50 ohms ~ NEW ~ in original manufacturers packaging NOTE: these are die (dice) and not SMT packaged parts. Wirebonding and die attach methods must be used. The Big Deal• Patented design eliminates in band spurs• Pass band cut-off up to 21 GHz• Stop band up to 35 GHz• Excellent repeatability through IPD* process• Unpackaged Die Form Features• Match to 50Ω in the stop band, eliminates undesired reflections• Cascadable• Excellent Power handling Applications• Harmonics Rejection• Satellite• Radar• Military & Space General DescriptionMini-Circuits’ XLF-173-D+ reflectionless filter die employs a novel filter topology which absorbs and terminates stop band signals internally rather than reflecting them back to the source. This new capability enables unique applications for filter circuits beyond those suited to traditional approaches. Traditional filtersare reflective in the stop band, sending signals back to the source at 100% of the power level. These reflections interact with neighboring components and often result in inter-modulation and other interferences.Reflectionless filters eliminate stop band reflections, allowing them to be paired with sensitive devices andused in applications that otherwise require circuits such as isolation amplifiers or attenuators.
