Applications • Receiver protection Features • High power, midrange and clean-up designs • Low insertion loss (0.1 dB at 10 GHz) • Power handling to 66 dBm • Tight control of basewidth Limiter Diodes Skyworks’ broad product portfolio includes limiter diodes as packaged and bondable silicon chips, in addition to ceramic hermetic packaged and plastic surface mount packaged devices for receiver protection applications. 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 basewidth PIN limiter diodes. Limiter circuits employing these devices 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 multistage limiter applications. The mesa constructed, thin basewidth, low capacitance CLA4601-000, CLA4602-000, CLA4604-000 and CLA4605-000 are designed for low-level and cleanup applications. The CLA4603-000, and CLA4606-000 through CLA4608-000 are planar designs designated for high-power and mid-range applications.

In the case when no large input signal is present, the impedance of the limiter diode is at its maximum, thereby producing minimum insertion loss, typically less than 0.5 dB. The presence of a large input signal temporarily forces the impedance of the diode to a much lower value, producing an impedance mismatch which reflects the majority of the input signal power back towards its source.
