DATA SHEET CLA4611-085LF: Surface-Mount Limiter Diode Applications Low-loss, high-power limiters Anode Anode Receiver protectors (Pin 3) (Pin 1) Features Low small signal insertion loss: 0.3 dB Typical threshold level: +25 dBm Cathode (Pin 2, Exposed Paddle) Low capacitance: 0.25 pF Low-profile, ultra-miniature QFN (3-pin, 2 x 2 mm) package Figure 1. CLA4611-085LF Block Diagram (MSL1, 260 C per JEDEC J-STD-020) Description TM Skyworks Green products are compliant with The CLA4611-085LF is a surface-mountable, low-capacitance all applicable legislation and are halogen-free. silicon PIN limiter diode designed as a shunt connected PIN diode For additional information, refer to Skyworks for high power limiter applications from 10 MHz to over 6 GHz. TM Denition of Green , document number Maximum resistance at 10 mA is 1.2 and maximum SQ040074. capacitance at 38 V is 0.25 pF (typical). The combination of low junction capacitance, low parasitic inductance, low thermal resistance, and nominal 12 m 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. Skyworks Solutions, Inc.

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. ESD HANDLING: 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 when handling or transporting. Static charges may easily produce potentials of several kilovolts on the human body or equipment, which can discharge without detection. Industry- standard ESD handling precautions should be used at all times. 1 Table 2.
