Measurement Methods

Measurement Methods

The treatment given here is introductory, and will assist the reader who wishes to consult the standard texts for further detail on measurement techniques. For measurements on mixers and frequency doublers, please refer to the application notes on these subjects.
Coupler Theoretical Main-Line Loss Calculation (AN-30-004)

Coupler Theoretical Main-Line Loss Calculation (AN-30-004)

The main-line loss of a coupler is defined as the loss between the input and output ports. This articles derives the formula for conversion between the fraction of the input power that is outputted at the coupled port.
Pairing Mixers with Reflectionless Filters to Improve System Performance

Pairing Mixers with Reflectionless Filters to Improve System Performance

Traditional filter designs employ circuits which reject undesired signals by reflecting them back to the source. There are many applications in which these reflections produce intermodulation products, gain ripples and other problems in system performance.
Electronic Attenuators

Electronic Attenuators

A useful feature of Mini-Circuits' electronic attenuators is the ability for either a positive or negative control current to provide the same amount of attenuation between input and output; this makes it useful for biphase modulation applications.
Phase Locked Loop Fundamentals

Phase Locked Loop Fundamentals

The basic form of a phase locked loop (PLL) consists of a voltage controlled oscillator (VCO), a phase detector (PD), and a filter. In its more general form, the PLL may also contain a mixer and a digital divider.
Do It Yourself Low-Cost Directional Couplers

Do It Yourself Low-Cost Directional Couplers

There is a continuing demand to reduce the cost and increase the performance and quality at the same time. Mini-Circuits is working to satisfy these goals and has introduced a new directional couplers series to satisfy the demands of the market.
