MKU XO 1 PLL

PLL-stabilized Crystal Oscillator

Different frequencies (see table)

The PLL fixed frequency crystal oscillator MKU XO 1 PLL can replace an OCXO for G and G2 transverter modules and for 12 GHz local oscillator modules. The transverters and LO modules need to have an input for an external oscillator (option 01, ext. OCXO). This option can be added, if it is not yet installed. With the oscillator module MKU XO 1 PLL, the high frequency accuracy of 10 MHz sources can be used to gain improved performance.
