DATA SHEET SKY65723-81: Low-Noise Amplifier Front-End Module with GPS/GNSS/BDS Pre-Filter Applications GPS/GNSS/BDS radio receivers Global Navigation Satellite Systems (GLONASS) Fitness/activity trackers Bias/Enable Smartphones Laptop PCs and tablets Input Output LNA RF OUT RF IN Match Match Features 203923-001 Figure 1. SKY65723-81 Block Diagram Small signal gain: 16.5 dB typical Low noise figure: 1.5 dB typical Excellent out-of-band rejection Description Low current consumption The SKY65723-81 is a front-end module (FEM) with an integrated low-noise amplifier (LNA) and pre-filter designed for Global Input/output impedance internally matched to 50 Positioning System/Global Navigation Satellite System/Beidou Single DC supply: 1.62 to 3.6 V Navigation Satellite System (GPS/GNSS/BDS) receiver Minimal number of external components required applications. The device provides high linearity, excellent gain, a Small MCM (6-pin, 1.7 x 2.3 mm) package high 1 dB input compression point (IP1dB), and a superior noise (MSL3, 260 C per JEDEC J-STD-020) figure (NF). The pre-filter provides the low in-band insertion loss and integrated notch filtering for excellent rejections of the cellular, TM Skyworks Green products are compliant with PCS, and WLAN frequency bands. The SKY65723-81 uses all applicable legislation and are halogen-free. surface-mount technology (SMT) in the form of a 1.7 x 2.3 mm For additional information, refer to Skyworks Multi-Chip Module (MCM) package, which allows for a highly TM Denition of Green , document number manufacturable and low-cost solution.

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.
