2.0 - 4.5 / 0.4 - 2.0 GHz prescaler
The 310-027015-001 LO divider provides the system designer with a compact, fast-switching building block for LO division applications.
Cascades of solid-state prescalers provide frequency division by a factor of 2, 4 or 8. Each of the prescaler chains is followed by a filter to improve the spurious response and an amplitude corrector to achieve flat frequency response. Operating band is selected using two band select control pins.
A NULL mode is available to disable the module’s output. Solid-state MMIC switches provide high-speed selection of the desired operating band.
