Count on the Noise Leader Noise Modules for bite The NC500 (through hole) and NC500SM (surface mount) Series noise modules are an economical solution for built-in test requirements. They contain complete bias circuits and require no external components. The surface mount package is suitable for mounting on microstrip. The modules produce extremely flat output power versus frequency characteristic that is insensitive to temperature and voltage variations. The NC500 Series modules are housed in a TO-8 metal can, and require 0.2 to 5 mA, while the 500SM Series modules are housed in a surface mount plastic package. Both typically require 5 mA and produce a minimum of 31 dB enr of white Gaussian noise. The NC510 and 510SM Series typically require 15 mA and have higher output with a minimum of 51 dB enr. Typical applications for these noise modules include built-in test equipment (bite), signal strength meters for cellular, pcs, catv, calibrators, spectrum analyzers, radar warning receivers (rwr), and dither A/D quantization error. Noise Com can optimize frequency range, voltage and output levels for specific applications. Most models are available from stock. Data Sheet NC500 / 500SM Series 200 kHz to 5 GHz When ordering, add the suffix “SM” to the model number to denote the surface mount version. If the suffix is not included, the drop-in version will be supplied.
