RF Transformer Tidbits

RF Transformer Tidbits

RF Transformer Tidbits RF Transformers are two, or more, port passive devices with a wide range of uses for many RF applications. One of the most common uses of an RF transformer is the Balun, which provides efficient coupling between unbalanced transmission circuits and balanced circuits. Other common uses are for impedance matching between circuits...

Voltage Controlled Oscillator Primer

Voltage Controlled Oscillator Primer

Voltage Controlled Oscillator Primer Voltage Controlled Oscillators (VCOs) are a key component to many tunable communications, radio, radar, sensing, and measurement systems. Essentially, a VCO is an oscillator that can be controlled by an input voltage, usually analog. Hence, adjusting the tuning voltage across its range also changes the VCOs output RF signal, proportionally. VCOs...

Coaxial and Waveguide Rotary Joints PE1402

Coaxial and Waveguide Rotary Joints

Coaxial and Waveguide Rotary Joints Rotary joints, unlike typical adapters, have the ability to rotate about the axis perpendicular to the wave propagation direction. While maintaining transmission properties, these joints can rotate freely 360 degrees. This type of joint is necessary for any application that has a rotating section, such as a rotary antenna (air...
