Regenerative Divider (LNRD5)

LNRD5 block


The LNRD5 is a regenerative frequency divide-by-two module with one f/2 output. This module includes an input amplifier to accommodate lower input power applications. The input power can range from 0 to +3 dBm. Division is accomplished with a low noise mixer and amplifier yielding exceptional phase noise performance. The module includes the high-level mixer, filters, amplifier and power splitter. The typical output noise floor is -170 dBc/Hz (-168 dBc/Hz, guaranteed) and the close-in noise is significantly lower than the best crystal sources making the LNRD5 a nearly ideal frequency divider. This divider is designed for a fixed input frequency between 2 GHz and 12 GHz.
