CLA4605-085LF Block Diagram Low capacitance: 0.32 pF Low profile, ultra-miniature QFN (3-pin, 2 x 2 mm) package (MSL1, 260 C per JEDEC J-STD-020) Description The CLA4605-085LF is a surface-mountable, low-capacitance silicon PIN limiter diode designed as a shunt connected PIN diode TM Skyworks Green products are compliant with for high power limiter applications from 10 MHz to over 6 GHz. all applicable legislation and are halogen-free. Maximum resistance at 10 mA is 2 and maximum capacitance For additional information, refer to Skyworks at 6 V is 0.45 pF. The combination of low junction capacitance, TM Denition of Green , document number low parasitic inductance, low thermal resistance, and nominal SQ040074. 2 um I-region width, makes the CLA4605-085LF useful in large signal limiter applications. The threshold level is +9 dBm, nominal. A block diagram of the CLA4605-085LF is shown in Figure 1. The absolute maximum ratings of the CLA4605-085LF are provided in Table 1. Electrical specifications are provided in Table 2. Typical performance characteristics of the CLA4605-085LF are provided in Table 3 and illustrated in Figures 4 and 5. 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.

Recovery time represents the transition time from the high-loss state to the low-loss state following the removal of a high-power input. It is defined as the time from the end of the high power pulse to the time when insertion loss has returned to within 3 dB of the quiescent (low-power) state. Skyworks Solutions, Inc.
