The X-Series reflectionless monolithic-microwave-integrated-circuit (MMIC) RF/microwave filters absorb and terminate stopband signals rather than reflecting them back to the source. Available in lowpass, highpass, and bandpass configurations, these compact filters can be specified with passbands from DC to 17 GHz and stopbands to 35 GHz. Measuring just 3 × 3 mm, an example of the lowpass filters, model XLF-173+ passes signals from DC to 17 GHz with typical passband insertion loss of 2.3 dB. Rejection is typically 17 dB from 23.9 to 26.0 GHz and typically 21 dB from 26 to 33 GHz. The filter has an operating temperature range of -55 to +105°C and handles as much as 2 W passband signal power.
