Model 2808-ALN Phase Locked Oscillator


Designed to replace the crystal oscillator LO chain in a 5760MHz Transverter design, the Model 2808-ALN will provide superior low noise performance approaching the Phase Noise performance of a crystal oscillator multiplier chain.

Now there is an alternative to the unstable crystal oscillator chain that drifts constantly. The Model 2808-ALN allows precise receiver/transmitter frequency control using a stable external 10 MHz or 100 MHz reference oscillator like a TCXO, Oven Controlled Oscillator or a Rubidium Oscillator. The Model 2808-ALN may used to replace any Local Oscillator chain by providing an external X2 multiplier ahead of any 5760MHz mixer assembly.

The Model 2808-ALN outputs a single ultra low noise 2808MHz signal. With a minimum of +17 dBm of output power, the oscillator is perfect for driving 3-dB power spliiters, multipliers and power amplifier stages. The ultra low noise performance of the Model 2808-ALN begins to approach crystal oscillator phase noise performance. This allows the unit to be used for such things as EME communications, long-haul low noise communications and digital operations like JT65 and similar modes. With both end of a communications link using a Model 2808-ALN, both stations will be absolutly on the same frequency when locked to a 10 MHz GPS disiplined oscillator reference. No more hunting around the dial for the other operator.
