SKY65452-92LF Block Diagram Digital video recorders (DVRs) Description Features The SKY65452-92LF is a Microwave Monolithic Integrated Circuit Small signal gain: 15 dB typical (MMIC) front-end low-noise amplifier (LNA) designed especially Best-in-class linearity for set-top-box applications. The device provides high linearity, Low noise figure: 2.9 dB typical excellent gain, and best-in-class composite triple beat (CTB) and composite second order (CSO). There are minimal external Input/output impedance internally matched to 75 components. Minimal number of external components required The SKY65452-92LF is optimized to operate between 40 MHz and Small 6-pin SC-70 (SC-88, SOT-363) plastic SMT package 1 GHz, which makes it ideal for cable and terrestrial set-top-box and home-gateway applications. TM The SKY65452-92LF is fabricated using SiGe BiCMOS technology. Skyworks Green products are compliant with The LNA uses surface-mount technology (SMT) in a 6-pin SC-70 all applicable legislation and are halogen-free. package.

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. Table 3.
