The X-Series of reflectionless monolithic-microwave-integrated-circuit (MMIC) filters includes two- and three-section filters with as much as 50-dB stopband rejection. The compact filters, with passbands from dc to 21 GHz and stopbands as high as 26 GHz, employ a patented filter topology to eliminate stopband reflections, which can be sources for intermodulation distortion (IMD). The filters team well with sensitive reflective components, such as mixers and multipliers, as well as wideband amplifiers. Model XHF-652M-D+ is one example. The RoHS-compliant highpass filter has a passband of 6.6 to 11.0 GHz and stopband of dc to 5 GHz; typical stopband rejection is 38 dB. The 50-Ω filter die, which measures 1400 × 1400 µm, operates from −55 to +105°C.
