Low-Noise Divider Ensemble

Transform a single low-noise microwave source into multiple low-noise channels... just think of the possibilities.

With the advent of microwave sources exhibiting phase and amplitude noise far better than multiplied quartz or SAW devices, designers now require a module which divides both the microwave source frequency and its noise while preserving the sinusoidal form of the original source.

Poseidon's LNDE is a product of the company's microwave ingenuity and phase noise expertise. It applies old ideas to new scenarios using ultra low-noise direct X-band sources (the Poseidon sapphire oscillator range). The compact LNDEs are required to translate the spectrally pure signals of sapphire oscillators to lower frequencies with minimum degradation of the carrier. The LNDE divides its input frequency and reduces close-to-the-carrier phase noise by almost 6dB (the theoretical limit).

The divider allows system designers to divide an oscillator's signal to produce lower frequency signals. These signals can then be mixed to produce a range of outputs from 500 MHz to 20 GHz. Such a scheme lends itself readily to the creation of very low noise microwave synthesizers and Direct Digital Synthesis (DDS) clocks.

Poseidon's Low Noise Divider Ensemble (LNDE) provides high output levels combined with low phase noise at the following divided frequencies:

When the LNDE is driven by one of PSI's low phase noise sapphire oscillators these outputs can provide the lowest phase noise signals reported at these frequencies.

Notes

• Poseidon Scientific Instruments has a continuous development policy and features are subject to change without notice.
• Phase and amplitude noise measurements are based on techniques specified in National Institute of Standards and Technology (NIST) Technical Note 1337.
• Supplemental characteristics are supplied to provide further useful information and should be treated as “typical” performance. Actual performance may vary depending on operating environment and other factors.
