MPD Fully Functioning During the Covid-19 Emergency

We just thought we’d let all of you know that it is business as usual at Octagon Communications and MPD. All necessary precautions have been taken, and, as several of our staffers already work remotely, the office is open for business until we are told otherwise.

The July issue of MPD will arrive on schedule, and of course our website and the digital edition will continue to be available.

Feel free to contact any of us with questions or concerns!

We hope that you and your families are safe and healthy.

Low Pass Filter Rejects Noise Beyond 5 GHz

Model LFCW-5000+ is an extremely compact low pass filter based on rugged low temperature cofired ceramic (LTCC) technology. With a low-loss passband of DC to 5 GHz and stopband extending from 5 to 26.5 GHz, the filter can handle power levels to 3W in a tiny 0603 surface mount technology (SMT) configuration with wraparound terminations that supports the densest circuit designs. The 50 ohm low pass filter achieves typical passband insertion loss of 1.6 dB from DC to 5 GHz with low passband VSWR of typically 1.60:1 and 3 dB cutoff frequency of 5750 MHz. Stopband rejection is typically 40 dB from 7.2 to 7.6 GHz, 43 dB from 7.6 to 11.0 GHz, 34 dB from 11.0 to 16.0 GHz, and 15 dB from 16.0 to 26.5 GHz. The stopband VSWR is typically 20.0:1 from 7.2 to 26.5 GHz. Suitable for a wide range of commercial and military applications, including harmonic rejection, the LTCC low pass filter measures 0.063 x 0.032 x 0.024” and handles operating temperatures from -55 to +100ºC.
