ZXBF SERIES

2 to 21 GHz

THE BIG DEALy Patented design terminates Stopband signals
y Stopband up to 40 GHz
y High Stopband rejection, up to 60 dB

PRODUCT OVERVIEW
Mini-Circuits’ ZXBF Series reflectionless filters employs a novel filter topology which absorbs and terminates stop band signals
internally rather than reflecting them back to the source. Reflectionless filters eliminate stopband reflections, allowing them to bepaired with sensitive devices and used in applications that otherwise require circuits such as isolation amplifiers or attenuators.
This is developed in a new broadband, stable connectorized package.

KEY FEATURES
FeatureAdvantages

Easy integration with sensitive reflectivecomponents, e.g. mixers, multipliers

Reflectionless filters absorb unwanted signals, preventing reflections back to the source. This reduces generationof additional unwanted signals without the need for extra components like attenuators, improving system dynamicrange.

Cascadable

Reflectionless filters can be cascaded in multiple sections to provide sharper and higher attenuation, while also
preventing any standing waves that could affect pass band signals.

Excellent stability over temperature

Minimal variation in electrical performance across temperature.

Operating temperature up to 105˚C

Suitable for operation close to high power components.

Broadband connectorized package

The connectorized package works well even in high frequencies and easy to interface with other devices. This is well
suited for test setups.
