VCO Test Methods

How to Measure Output Power and Frequency Figure 1 is a block diagram of the setup for this measurement. Well regulated power supplies are recommended for tuning and VCO supplies. Bias tee’s in the DC and tuning voltage lines help reduce the power supply noise....

Oscillator Fundamentals An oscillator circuit can be modeled as shown in Figure 1 as the combination of an amplifier with gain A (jω) and a feedback network (jω), having frequency-dependent open-loop gain H (jω) = ßA. Figure 1: An oscillator may be modeled as the...
