CLA4603 Series

Silicon Limiter Diodes, Packaged and Bondable Chips

The Skyworks CLA series of silicon limiter diodes provides passive receiver protection over a wide range of frequencies from 100 MHz to over 20 GHz. These devices use a well-established silicon technology resulting in high resistivity and tightly controlled base width PIN limiter diodes. Limiter circuits using these devices perform with strong limiting action and low loss.

The CLA series consists of ten individual chip designs of different intrinsic region base widths and capacitances designed to accommodate multi-stage limiter applications. The CLA4603 series are planar designs designated for high-power and mid-range applications.

CLA4603 Series includes CLA4603-203, CLA4603-210, CLA4603-219 and CLA4603-240.
