SMT noise sources cover 0.2MHz to 3GHz frequency ranges

April 4, 2021  Stephen Law

FAIRVIEW MICROWAVE Series of miniature SMT packaged noise sources are suitable for built-in test equipment, dithering for increased dynamic range of A/D converters and as a source for bit error rate testing. Product series includes nine models with dual in-line pin (DIP) and industry standard SMT gullwing pin surface mount packaging options. Devices cover frequency ranges from 0.2MHz to 3GHz and provide a source of additive white gaussian noise (AWGN) with a crest factor of 5:1. The DIP models boast a noise output power level of -5dBm. The SMT gullwing pin models in this line feature high output ENR levels ranging from 31 dB to 51 dB. The rugged 50 Ohm designs can operate over a wide temperature range of -55°C to +125°C and require dc voltage levels of +12 Vdc or +15 Vdc.
