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.
