Test & Measurement

Test and measurement baluns are connectorized modules that can be used in laboratory settings or built into temporary or permanent test sets. They are hand tuned to offer superior amplitude balance, phase balance, and common mode rejection ratio up to 67 GHz. Important specifications to consider when selecting a test and measurement balun include frequency coverage, excess insertion loss, and isolation between balanced ports. Data applications require a balun with frequency coverage to low frequencies, typically below 1 MHz. For converting a differential signal to a single ended signal it is best to use a balun with isolation, which is functionally equivalent to a 180˚ hybrid. For more information on how these specifications can affect system performance, consult our balun primer and tech notes.

Surface Mounts

Our surface mount baluns offer the best phase balance, amplitude balance, and common mode rejection over the widest bandwidths of any product commercially available. These surface mount baluns are commonly used to interface to analog to digital converters, digital to analog converters, and used in differential cable test sets.
Unlike competing transformer baluns, our broadband baluns use a unique architecture combined with sophisticated and proprietary assembly techniques to provide the highest performance balun on the market. For applications above 1 GHz Marki also offers lower cost, capacitively-coupled baluns.

Inverters

Pulse inverters are available as connectorized modules up to 65 GHz operation. These laboratory devices use both magnetic and capacitive coupling to create an inverted or negative version of a voltage signal. In the frequency domain it introduces a broadband 180˚ phase shift to the input signal, while maintaining a flat group delay to ensure signal integrity.
