Pasternack coaxial RF noise sources (also known as noise generators) are diode-based microwave components that produce white noise for system performance evaluation such as noise figure. RF noise sources / noise generators from Pasternack are commonly used in production and lab test environments. Our RF noise sources are available with two different noise outputs including medium noise sources and high noise sources.50 Ohm RF noise sources are available with SMA RF outputs and BNC bias inputs or SMA connector inputs. Our RF noise sources have operating frequencies ranging from 1 GHz to 18 GHz. These RF noise sources have a maximum noise output between 15.5 dB and 35 dB excess noise ratio (ENR). Many of our RF coaxial noise sources are REACH or RoHS compliant.The ISO 9001:2008 registered Pasternack facility ships all RF noise sources from stock the same day you order them. Pasternack Enterprises offers the broadest and deepest inventory of RF and microwave components available. Expert technical support and friendly customer service personnel are always here to assist you. ([email protected], [email protected], 866-727-8376 US and Canada or +1-949-261-1920 International).
