XHF2-Series

50

Ω

DC to 30 GHz

CASE STYLE: MC1630-1

The Big Deal

• Patented design eliminates in band spurs

• Pass band cut-off up to 18.3 GHz

• Stop band up to 30 GHz

• Excellent repeatability through IPD* process

Product Overview

Mini-Circuits’ XHF2-Series reflectionless filters employs a novel filter topology which absorbs and ter-

minates 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 which

interact with neighboring components and often result in intermodulation and other interferences. Reflec-

tionless 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.

Key Features

Advantages

Easy integration with sensitive reflective

components, e.g. mixers, multipliers

Reflectionless filters absorb unwanted signals, 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 sav-

ing board space.

Enables stable integration of wideband

amplifiers

Because reflectionless filters maintain good impedance in the stop band; 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

pass band signals.

Excellent power handling in a tiny surface

mount device

High power handling extends the usability of these filters to the transmit path for

inter-stage filtering.

Small size, 2x2mm QFN

Allows replacement of filter/attenuator pairs with a single reflectionless filter, sav-

ing 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.
