The CRO4187E-LF from Z-communications is a Voltage Controlled Oscillator which can be tuned to a frequency from 4187 to 4188 MHz. The VCO provides a spectrally clean signal with a phase noise as low as -108 dBc/Hz at a 10 kHz offset (1 Hz BW). It has a tuning voltage from 0.5 to 4.5 V and requires a supply voltage of 8 V to operate.
The VCO delivers an output power of 3.5 dBm into a 50-ohm load. It has a typical second harmonic suppression of -15 dBc and operates over the temperature range of -40 to 85ºC. It is available in a surface-mount package and is ideal for microwave radios and satellite communications.
