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 nine
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 CLA4606000 through CLA4609-000 are planar designs designed for mid-range and high-power
applications.

A Single-Stage Limiter
Output Power vs. Input Power for a Single-Stage Limiter
The PIN limiter diode can be described as an incidentpower-controlled, variable resistor. 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.
