RF Components: Broadband Coaxial Noise Sources

RF Components: Broadband Coaxial Noise Sources Micronetics broadband coaxial microwave noise sources are depended on for built in test/calibration. This noise source family is designed in frequency ranges from 1 MHz to 26.5 GHz with an ENR from 14 dB to 55 dB.

The High ENR, are perfect for built in test situations where there is significant path loss between the output of the noise source and the receiver. Examples of this are where high directivity couplers are to feed the noise signal into the receiver thus minimizing the receiver's noise figure with another being one noise source being fed into a multi-way power splitter for a receiver system with many elements.

Micronetics Low ENR noise sources feature a large value embedded attenuator ideal for Y-factor tests. The attenuator serves dual purposes of lowering the ENR to a suitable Y-factor amplitude and also improves both on and off state VSWR which increases noise figure measurement accuracy.

Small Hermetic Hybrid Noise Sources are modules in drop-in and coaxial packaging.
