New SMT noise sources ideal for PWB applications

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

The new line of noise sources comprises nine models with DIP and industry-standard SMT gullwing pin surface-mount packaging options. They include frequency ranges from 0.2MHz to 3GHz and offer a source of AWGN with a crest factor of 5:1. The DIP models possess a noise output power level of -5dBm. The SMT gullwing pin models in this line provide high output ENR levels ranging from 31dB to 51dB. These rugged 50Ohm designs can perform over a wide temperature range of -55C to +125C and need DC voltage levels of +12VDC or +15VDC.

“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 8-10 week lead times and, instead, ship these products the same day with no minimum order quantity,” said Tim Galla, senior product line manager.

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