SKY65047-360LF Block Diagram Features Noise figure = 1.2 dB 915 MHz Description Noise figure = 0.8 dB 1575 MHz The SKY65047-360LF is a high linearity low-noise amplifier Noise figure = 1.1 dB 2450 MHz (LNA). The excellent gain, superior low-noise and low current Small signal gain = 16.6 dB 1575 MHz consumption makes the SKY65047-360LF ideal for use in wireless infrastructure applications. The device can also be used Low operating current = 7.2 mA in a variety of LNA applications. All active circuitry in the module External, adjustable bias setting is contained in a single Microwave Monolithic Integrated Circuit Built-in power-down control (MMIC). Single DC supply voltage, 2.7 V to 3.8 V The device is manufactured with an advanced silicon germanium Miniature DFN (8-pin, 2 x 2 mm) package (SiGe) process, which allows a single supply operation while (MSL1, 260 C per JEDEC J-STD-020) maintaining excellent low-noise performance and linearity. The SKY65047-360LF is provided in a low-cost, miniature 2 x 2 mm Dual Flat No-Lead (DFN) package. Skyworks Green products are compliant with all applicable legislation and are halogen-free. A functional block diagram is shown in Figure 1. The pin For additional information, refer to Skyworks configuration and package are shown in Figure 2.

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. 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. Skyworks Solutions, Inc.
