Product Pages
We design and manufacture a broad range of resistive devices for board-level applications using thin- and thick-film technology. These are enhanced to provide reliable performance in a wide range of frequencies.
Visit the pages below for detailed information on each product family.
Attenuators
Reduce RF signal power by a controlled amount while maintaining impedance match.
Terminations
Absorb RF energy at the end of a signal path to minimize unwanted reflections and preserve signal integrity.
Resistors
Provide precise resistance for current control and power dissipation in high-frequency and high-power circuits.
S-Parameter Data and Circuit Models
These measurement-based models, available for selected PowerFilm™ devices, are for use with microstrip applications. The models account for printed circuit board related parasitic effects and are substrate scalable, in that substrate height, dielectric constant, loss tangent, and solder pad terminal dimensions are input parameters. Each attenuator series model is dB value scalable and the resistor models are available for a variety of ohm values.
Each model includes complete documentation detailing the test fixtures used, measurement conditions, range of validity, and model-to-measurement data comparisons.
