Agilent VTO-3981-K, VTO-4301-K Voltage Controlled Oscillator
Data Sheet
Features · Operating frequency: 39.813 GHz or 43.018 GHz · Output power (50 load): 3 dBm minimum Description The VTO-3981-K and VTO-4301-K provide a fundamental, low jitter source as a key component for the data re-timing in the transmitter subsystem and clock and data recovery in the receiver of the 40 Gb fiber optic systems. The oscillator uses an extremely high performance low noise Agilent Silicon Bipolar transistor in conjunction with a hyperabr upt varactor diode to provide the tuning capability. The oscillator output is then coupled to an Agilent GaAs FET MMIC amplifier and MMIC multiplier chain to quadruple the frequency. Finally the output is filtered through a band pass filter prior to outputting the signal at 39.813 or 43.018 GHz.
