PIN Diode Limiter Modules

Skyworks' limiter modules are used in a variety of wireless communications and aerospace and defense applications. A limiter prevents overload by allowing RF signals below a certain threshold to pass through, but larger-signals exceeding the threshold become increasingly attenuated. A typical application is as a passive receiver protector in infrastructure or military RF systems for frequencies up to 6 GHz. Skyworks limiter modules are comprised of integrated PIN limiter diodes and DC blocking caps at the RF ports in a 2-lead MLP package. This improves performance, reduces circuit implementation complexity and PCB area required compared to designs using discrete components.

The SKY16601-555LF is a fully-integrated PIN diode low threshold limiter module in a surface-mount package. It is designed for use as a passive receiver protector in wireless or other RF systems for frequencies up to 6 GHz.

The SKY16602-632LF is a fully-integrated PIN limiter/Schottky diode module in a surface-mount package. It is designed for use as a passive receiver protector in wireless or other RF systems up to 4 GHz. Its very-low-threshold of 5 dBm also makes it useful as a fine clean-up limiter. The SKY16602-632LF expands Skyworks' portfolio of integrated limiter modules.
