More Product Information
- Complete bias circuits
- Requires no external components
- Optimizations available for frequency range and output levels
The NC520 low voltage (surface mount) noise module is an economic solution for built-in test requirements. It contains 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.
Typical applications for the NC520 module includes 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. Maury can optimize frequency range and output levels for specific applications.

Coaxial air lines are air-dielectric transmission lines with highly accurate dimensions that can be used as fundamental impedance standards in measurement and calibration applications, and may also be used to establish reference positions for measurements.
Bead supported air lines offer greater convenience and easier connections (the center conductor is automatically aligned by the dielectric bead for easy connection); beadless air lines offer better impedance and electrical length accuracies, as well as lower VSWR (the center conductor floats free in the air line body, and the male connector nut is retractable to facilitate insertion of the center conductor contact before the thread- on connection tightened.

Shielded, coaxial opens are used in the calibration of vector network analyzers to provide a nominal 180° phase offset from a compatible reference short over a wide range of frequencies. At these frequencies, open circuit terminations are inherently imperfect. Shielding the open essentially eliminates radiation loss, but creates a residual frequency-sensitive capacitance. An accurate knowledge of the open’s effective capacitance is essential to an accurate calibration of the analyzer. Maury opens are characterized for effective capacitance versus frequency by means of a fourth order polynomial curve fit, and the nominal capacitance coefficients are provided with each unit.
