Agilent VTO-1990-SMA, VTO-2150-SMA Voltage Controlled Oscillator
Data Sheet
Features · Operating frequency: 19.906 or 21.509 GHz · Output power (50 load): 3 dBm minimum · Modulation sensitivity: 10 to 20 MHz/V · Tuning voltage: 0 to 10 Volts
Amp X2 Output
Description The VTO-1990-SMA and VTO-2150-SMA provides a fundamental, low jitter source as a key component for the data re-timing in the transmitter subsystem and clock and data recover y 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 hyperabrupt 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 double the frequency. Finally the output is filtered through a bandpass filter prior to outputting the signal at 19.906 or 21.509 GHz.
