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
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 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
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.
