DAT Series Powered Through a Voltage Divider Network

DAT Series Powered Through a Voltage Divider Network

The Mini-Circuits DAT series is specified to operate with supply voltages over the range of 2.7V to 3.3V. When operating over this range, the parts meet all their specified performance parameters over the operating environmental ranges.
Figure of Merit of Mixer Intermod Performance

Figure of Merit of Mixer Intermod Performance

Higher IP3, up to a point, can be obtained in a mixer at the expense of LO power in a given design; or, by a better design. Higher LO power means more DC power and more hardware. This paper defines a figure of merit that will be useful in judging the IP3 performance of mixers.
Fixed Attenuators Help Minimize Impedance Mismatches

Fixed Attenuators Help Minimize Impedance Mismatches

Fixed attenuators are invaluable problem solvers for circuit-level and system-level designers. In addition to controlling amplitude levels, fixed attenuators can improve the impedance match between impedance-sensitive devices, such as amplifiers and filters, and provide the isolation needed to stabilize oscillators.
Improve Two-Tone, Third-Order Intermodulation Testing

Improve Two-Tone, Third-Order Intermodulation Testing

Two-tone, third-order distortion must be measured under specific performance conditions. The two most common errors in the measuring process are (1) failure to provide adequate isolation between the two input signal generators and proper impedance matching, and (2) insufficient filtering of the two input test signals.
RF Transformers

RF Transformers

RF transformers are widely used in low-power electronic circuits for impedance matching to achieve maximum power transfer, for voltage step-up or step-down, and for isolating DC from two circuits while maintaining ac continuity.
Automated Load Pull Measurement of Voltage Controlled Oscillators

Automated Load Pull Measurement of Voltage Controlled Oscillators

It is a standard industry practice to measure the variation of the frequency when the VCO output is seeing a load with 12 dB return loss. A skilled technician may take minutes to hours manually. Mini-Circuits has developed an electronic line stretcher that can be used to automate these measurements.
How RF Transformers Work and How They Are Measured

How RF Transformers Work and How They Are Measured

This article will describe the relationship between impedance relationships and transformer circuits with reference to transformers with turns ratios greater than 1:1 described as step-up.
