High-Linearity Dual PIN Diode Limiter 0.6 to 6.0 GHz

The SKY16603-632LF is a fully integrated dual PIN diode high-linearity 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. It features a low limiting threshold, low-insertion loss, excellent IIP3, and low IM distortion in a Dual Flat No Lead (DFN) package.

The SKY16603-632LF module is comprised of dual PIN limiter diodes and two DC blocking caps at the RF ports in a 2-lead DFN.

The small package design reduces printed circuit board area. The module can operate over the operating temperature range of -40˚C to +105˚C.
