Description
The CLA4611-085LF is a surface mountable, low capacitance
silicon PIN limiter diode designed as a shunt connected PIN diode
for high power limiter applications from 10 MHz to over 6 GHz.
Maximum resistance at 10 mA is 1.2 Ω and maximum
capacitance at 38 V is 0.25 pF (typical). The combination of low
junction capacitance, low parasitic inductance, low thermal
resistance, and nominal 12 μm I-region width, makes the
CLA4611-085LF useful in large signal limiter applications. The
threshold level is +25 dBm, nominal.
A block diagram of the CLA4611-085LF is shown in Figure 1. The
absolute maximum ratings of the CLA4611-085LF are provided in
Table 1. Electrical specifications are provided in Table 2.
Typical performance characteristics of the CLA4611-085LF are
provided in Table 3 and illustrated in Figure 4.

Note 1: Exposure to maximum rating conditions for extended periods may reduce device reliability. There is no damage to device with only one parameter set at the limit and all other
parameters set at or below their nominal value. Exceeding any of the limits listed here may result in permanent damage to the device.
CAUTION: Although this device is designed to be as robust as possible, electrostatic discharge (ESD) can damage this device. This device
must be protected at all times from ESD. Static charges may easily produce potentials of several kilovolts on the human body
or equipment, which can discharge without detection. Industry-standard ESD precautions should be used at all times.

 CLA4611-085LF
Functional Description
The PIN limiter diode can be described as an incident power
controlled, RF variable resistor. When there is no large input
signal present, the impedance of the limiter diode is at its
maximum, which produces minimum insertion loss, typically
less than 0.2 dB. The presence of a large input signal
temporarily forces the impedance of the diode to a much lower
value, which produces an impedance mismatch that reflects the
majority of the input signal power back towards its source.
During the limiting process, a DC current is generated by the
PIN limiter diode. The current is not the result of rectification,
but is the result of charge carriers being forced into the I layer
by the forward alternations of the large input signal. A complete
path must be provided for this current or the diode is not
capable of limiting. Therefore, an RF choke or similar structure
must be provided to complete the path for DC current flow.

The DC block capacitors shown in Figure 2 are optional; they
protect the limiter diode from external DC voltage that may be
present in the source or load circuits.
A cross section of the suggested printed circuit board design is
shown in Figure 3. The via shown in this view is critical, both for
electrical performance and for thermal performance. It is
recommended that several vias should be placed under the
entire footprint of the exposed paddle (pin 2) to minimize both
electrical inductance to the system ground and thermal
resistance to the system heat sink.
For more information about the operation of limiter diodes, refer
to the Skyworks Application Note, PIN Limiter Diodes in
Receiver Protectors, document number 200480.
