1.0 - 1.5 GHz
2.0 - 4.5 GHz
The 310-027013-001 LO Multiplier provides the system designer with a compact, fast-switching building block for Local Oscillator multiplication applications.
A pair of internal solid-state multipliers provides frequency multiplication by a factor of 2 or 3 depending upon the state of two band control lines. Internal four-channel bandpass filtering improves the spurious response.
An integral 3-way output switch routes the multiplied input LO signal to other modules based upon the states of two output control lines. A NULL mode is available to disable the module’s output.
