SKY65088 Block Diagram Description The SKY65088 is a Microwave Monolithic Integrated Circuit (MMIC) Global Positioning System (GPS) Low Noise Amplifier (LNA). The device has superior Noise Figure (NF), excellent gain, and a high 1 dB Input Compression Point (IP1dB). The SKY65088 is optimized to operate at 1.575 GHz, which makes it ideal for GPS radio receiver applications. The device is fabricated using Skyworks high reliability SiGe CMOS technology. The LNA uses Surface Mount Technology (SMT) in the form of a 1.5 x 2.0 mm Quad Flat No-Lead (QFN) package, which allows for a highly manufacturable and low-cost solution. A functional block diagram is shown in Figure 1. The pin configuration and package are shown in Figure 2. Signal pin assignments and functional pin descriptions are provided in Table 1.

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.
