Small size, low power consumption, low phase noise MMIC VCO using off-chip packaging resonator for mobile communication

摘要

An MMIC VCO with a new type of frequency tunable multilayer ceramic resonator for mobile communication is designed and fabricated for the 2 GHz band. The VCO presents a dramatic size reduction and a C/N performance of -100 dBc/Hz at 100 kHz. Its RF output power is about -3 dBm, the frequency tuning range is 110 MHz, and current consumption is 7mA of DC.
