The CVCO55CXT series is a coaxial based VCO with an internal proprietary frequency doubler. This family has low phase noise for its frequency of operation (i.e., -103 dBc/Hz at 10 kHz offset for a 5.4 GHz VCO). Due to Crystek’s very efficient proprietary frequency doubler, supply current consumption is less than 25 mA. The harmonics are reduced to a typical value of -25 dBc.
