Wiltron

Wiltron

Wiltron was a pioneering American manufacturer of RF and microwave test and measurement equipment, best known for producing vector network analyzers (VNAs), SWR bridges, and scalar network analyzers. Founded in the 1960s, Wiltron developed a strong reputation in the RF and microwave engineering community for precision instrumentation covering frequencies from low RF through microwave bands. The company was acquired by Anritsu in the 1990s, and many Wiltron instruments continue to be supported and used in laboratories worldwide.

Wiltron's product line addressed critical measurement needs in RF component characterization, antenna testing, and microwave circuit design. Their SWR bridges and transmission/reflection test sets provided engineers with tools for measuring impedance, reflection coefficient, and transmission parameters across coaxial and waveguide systems.

Key Product Lines

• Vector network analyzers for S-parameter measurement of RF and microwave components
• SWR bridges and transmission/reflection test sets for impedance and return loss measurement
• Scalar network analyzers for frequency response and gain/loss characterization

Industries Served

Wiltron equipment was widely used in aerospace and defense, telecommunications, satellite communications, and RF and microwave component manufacturing. Their instruments supported antenna characterization, filter and amplifier testing, radar system development, and wireless communication research in government and commercial laboratories.
