Isolator/Circulator withBest-in-class Intermodulation Distortion Performance

摘要

The increased use of multi-carrier radios in cellular infrastructure systems is driving the requirement for high linearity components, especially in the power amplifier chain. Isolators and circulators have historically been known to impact the overall intermodulation distortion (IMD) performance of a wireless transmission system and are therefore critical to specify. Engineering teams from Sky-works Solutions and Trans-Tech (a subsidiary of Skyworks Solutions) have successfully developed new materials/device designs for isolators and circulators that are optimized for IMD performance and offer the industry very low IMD specifications. The new SKYFR-000700 circulator has IMD performance better than -90 dBc with two +47 dBm tones.
