The LNRD4 is a regenerative frequency divide-by-two module with an optional 3/2 frequency output. This module adds an input amplifier to the LNRD2 topology to accommodate lower input power applications. The input power can range from +10 to +20 dBm. Division is accomplished with a low noise mixer and amplifier yielding exceptional phase noise performance. The module includes the high-level mixer, filters, amplifiers and power splitters necessary to provide two f/2 outputs and one 3f/2 output. The typical output noise floor is -175 dBc/Hz (-172 dBc/Hz, guaranteed) and the close-in noise is significantly lower than the best crystal sources making the LNRD4 a nearly ideal frequency divider. This divider is designed for a fixed input frequency between 10 MHz and 2000 MHz.
