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
components, e.g. mixers, multipliers
Reflectionless filters absorb unwanted signals falling in filter stopband, preventing
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 intermodulation products is needed.
Enables stable integration of wideband
amplifiers
Because reflectionless filters maintain good impedance in the stopband; they
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
mount device up to 7W in passband
High power handling extends the usability of these filters to the transmit path for
inter-stage filtering.
Small size,
3x3mm/ 4x4 mm/ 5x5mm QFN
Allows replacement of filter/attenuator pairs with a single reflectionless filter,
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 105˚C
Suitable for operation close to high power components.
*IPD – Integrated Passive Device, is a GaAs semiconductor process

General Description
Mini-Circuits’ XLF-13H+ three-section reflectionless filter 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
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.

Reflectionless Filter Application Note
Application Circuit Example
Pairing mixers with reflectionless filters to improve system dynamic range
Test block diagram: IF output reflection spectrum with single input frequency
Figure 1. IF output reflection spectrum without filter
Figure 2. IF output reflection spectrum with conventional filter
An application circuit was assembled to measure the IF reflection
spectrum at the output of a mixer when the mixer was paired with a
conventional filter versus a reflectionless filter.
While the conventional filter reduces the reflections present when
the mixer is used alone (no filter), the reflectionless filter virtually
eliminates those reflections altogether.
The reflected signal at marker 1 in the figures above exhibits a
reduction of more than 20 dB from -28.7 dBm to -50.3 dBm when
the reflectionless filter is used as compared to the conventional filter,
thus eliminating unwanted spurious mixing products and improvingsystem dynamic range.
For more information, refer to application note AN-75-007
