Description SILICON Skyworks’ CLA series of silicon limiter diode chips provides passive receiver protection over a wide range of frequencies from 100 MHz to beyond 30 GHz. These devices utilize Skyworks’ well established silicon technology for high resistivity and tightly controlled thin base width PIN limiter diodes. Limiter circuits employing these devices will perform with strong limiting action and low loss. The CLA series consists of eight individual chip designs of different intrinsic region basewidths and capacitances designed to accommodate multi-stage limiter applications. The mesa constructed, thin basewidth, low capacitance CLA4601-000, CLA4602-000, CLA4604-000 and CLA4605-000 are designed for low level and clean-up applications. The CLA4603-000, CLA4606-000 through CLA4608-000 are planar designs designated for high power and mid-range applications.
