Practical Techniques It is always a good design philosophy to provide RF bypassing of power and DC control lines to the VCO. This is indeed the case when the VCO is located some distance away from the power supply. RF chokes and good bypassing capacitors of...

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....

Characterizing Phase Noise The term phase noise is widely used for describing short term random frequency fluctuations of a signal. Frequency stability is a measure of the degree to which an oscillator maintains the same value of frequency over a given time. This may...

Introduction Voltage controlled oscillators (VCOs) are normally designed for operation into ideal 50Ω impedance. Actual loads into which they work are seldom ideal. It is a standard industry practice to measure the variation of the frequency when the VCO output is...

Electronic line stretchers offer controlled phase shifts over wide frequency ranges to simplify once tedious VCO measurements. Voltage controlled oscillators (VCOs) are normally designed for operation in an ideal 50Ω environment. However, the actual load that these...
