XHF XLF MMIC REFLECTIONLESS FILTERS 50 DC to 21 GHz The Big Deal High Stopband rejection, up to 50 dB Patented design terminates stopband signals Pass band cut-off up to 11 GHz X-Series Available in Low Pass Stop band up to 26 GHz & High Pass designs Excellent repeatability through IPD* process Product Overview Mini-Circuits X-Series of reflectionless filters now includes 2- and 3-section models, giving you ultra-high rejection in the stopband up to 50 dB Reflectionless filters employ a patented filter topology which absorbs and terminates stopband 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 filters are reflective in the stopband, sending signals back to the source at 100% power. These reflections interact with neighboring components and often result in intermodulation and other interferences. By eliminating stopband reflections, reflectionless filters can readily be paired with sensitive devices and used in applications that otherwise require circuits such as isolation amplifiers or attenuators. Key Features Advantages Easy integration with sensitive reflective Reflectionless filters absorb unwanted signals falling in filter stopband, preventing components, e.g. mixers, multipliers reflections back to the source. This reduces generation of additional unwanted signals without the need for extra components like attenuators, improving system dynamic range and saving board space. High stopband rejection, up to 50 dB Ideal for applications where suppression of strong spurious signals and intermod- ulation products is needed. Enables stable integration of wideband Because reflectionless filters maintain good impedance in the stopband they amplifiers can be integrated with high gain, wideband amplifiers without the risk of creating instabilities in these out of band regions. Cascadable Reflectionless filters can be cascaded in multiple sections to provide sharper and higher attenuation, while also preventing any standing waves that could affect passband signals. Low & highpass filters can be cascaded to realize bandpass filters. Excellent power handling in a tiny surface High power handling extends the usability of these filters to the transmit path for mount device up to 7W in passband inter-stage filtering. Small size, Allows replacement of filter/attenuator pairs with a single reflectionless filter, 3x3mm/ 4x4 mm/ 5x5mm QFN saving board space. Excellent repeatability of RF performance Through semiconductor IPD process, X-series filters are inherently repeatable for large volume production. Excellent stability over temperature With 0.3 dB variation over temperature ideal for use in wide temperature range applications without the need for additional temperature compensation. Operating temperature up to 105C Suitable for operation close to high power components. Notes *IPD Integrated Passive Device, is a GaAs semiconductor process A.

This new capability enables unique applications for filter circuits beyond those suited to traditional approaches. Traditional filters are 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 and used in applications that otherwise require circuits such as isolation amplifiers or attenuators. simplified schematic and pad description NC NC NC NC NC NC 24 23 22 21 20 19 NC 1 18 NC GND 2 17 GND RF-IN 3 16 RF-OUT PADDLE (GROUND) GND 4 15 GND NC 5 14 NC NC 6 13 NC 7 8 9 10 11 12 NC NC NC NC NC NC Pad Function Description Number RF-IN 3 RF Input Pad RF-OUT 16 RF Output Pad GND 2,4,15,17 & paddle Connected to ground NC (GND Externally) 1, 5-14,18-24 No internal connection Notes A.
