Fairview Microwave has just debuted a new series of miniature SMT packaged noise sources that are suited for built-in test equipment, dithering for increased dynamic range of A/D converters and as a source for bit error rate testing.

Applications include microwave radio, communication systems, military and commercial radar, base station infrastructure, test and measurement, and telecom data links.

Fairview Microwave’s new line of noise sources includes nine models with dual in-line pin (DIP) and industry standard SMT gullwing pin surface mount packaging options. They cover frequency ranges from 0.2 MHz to 3 GHz 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. These 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.

“With this addition of miniature SMT packaged noise sources, we can fully address designers’ needs for circuit board level proof-of-concept or prototype applications. Plus, we’re able to bypass the normal 8-ten week lead times and, instead, ship these products the same day with no minimum order quantity,” said Tim Galla, Senior Product Line Manager.
