One of the problems comes from crosstalk between the VCO and low noise amplifier. |
While this VCO was developed for several specific applications, we believe it has the potential to become a key product for Vari-L over the long term. |
The VCO operates at twice the fundamental frequency to reduce spurious emissions and frequency pulling problems. |
Low-voltage operation below the threshold voltage of the transistor is achieved by combining the features of a class-D VCO and dynamic control technique of the supply voltage. |
The RS1007RF integrates a low pass filter with DC offset calibration, mixer, VGA, Delta Sigma fractional N PLL, VCO and RC auto calibration circuit. |
