DATA SHEET SKY65605-21: BDS/GPS/GNSS Low-Noise Amplifier Applications BDS/GPS/GNSS radio receivers Global Navigation Satellite Systems (GLONASS) Smartphones Tablet/laptop PCs Enable Personal navigation devices Input Output LNA RF OUT RF IN Match Match Features Y2224 Small signal gain: 19 dB typical Figure 1. SKY65605-21 Block Diagram High in-band IIP3: -5 dBm Low noise figure: 0.6 dB typical Description High IP1dB: -14.5 dBm The SKY65605-21 is a Microwave Monolithic Integrated Circuit Low current consumption: 3.6 mA (MMIC) front-end low-noise amplifier (LNA) designed for BeiDou Output impedance internally matched to 50 Satellite Navigation System/Global Positioning System/Global Single DC supply: 1.8 to 2.85 V Navigation Satellite System (BDS/GPS/GNSS) receiver applications. The device provides high linearity, excellent gain, a Minimal number of external components required high 1 dB input compression point (IP1dB), and a superior noise Ultra-small QFN (6-pin, 0.7 x 1.1 mm) package figure (NF). (MSL1, 260 C per JEDEC J-STD-020) The SKY65605-21 is optimized to operate from 1.559 to 1.606 GHz, which makes it ideal for BDS/GPS/GNSS radio receiver applications. The SKY65605-21 is fabricated using advanced SiGe BiCMOS technology. The LNA uses surface-mount technology (SMT) in the form of a 0.7 x 1.1 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.

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.
