FEATURES
Pout: +5.0 dBm Phase Noise: -106 dBc/Hz @100 KHz No External Resonator Needed Single Supply: +3V @ 30 mA 24 Lead 4x4mm QFN Package: 9 mm2GENERAL DESCRIPTION
Covering 3.9 to 4.45 GHz, the VCO’s phase noise performance is excellent over temperature, shock, vibration and process due to the oscillator’s monolithic structure. Power output is 5.0 dBm typical from a single supply of +3V @ 30 mA. VCOS - SMT 12 - 30ELECTRICAL SPECIFICATIONS
