DATA SHEET SKY65943-11: GNSS Low-Noise Amplifier Front-End Module with Integrated Pre-Filter and Post-Filter Applications Wearables Action cameras Drones Bias/Enable Personal navigation devices Output LNA RF OUT RF IN Match GNSS radio receivers 204404-001 Features Input Match Small signal gain: 16 dB Figure 1. SKY65943-11 Block Diagram Out-of-band P1dB: +6 dBm Out-of-band rejection: +80 dBc, 1627 to 1660 MHz Description Low noise figure: 1.7 dB The SKY65943-11 is a front-end module (FEM) with an integrated Low current consumption: 2.9 mA 1.8 V low-noise amplifier (LNA) and pre-filter and post-filter designed for Global Navigation Satellite System (GNSS) receiver Input/output impedance internally matched to 50 applications. The device provides high gain, excellent out-of-band Single DC supply: 1.62 to 3.3 V rejection, and low noise figure. The pre-filter and post-filter Minimum number of external SMT devices required provide low in-band insertion loss and excellent rejection for the cellular, PCS, and WLAN frequency bands. Output matching Small MCM (10-pin, 2.5 x 2.5 mm) package components are embedded inside the device. Only one external (MSL3, 260 C per JEDEC J-STD-020) input matching inductor is required. The SKY65943-11 is optimized to operate at 1559 to 1606 MHz, TM which makes it ideal for GPS / GLONASS / Galileo/Compass / Skyworks Green products are compliant with QZSS radio receiver applications. all applicable legislation and are halogen-free. For additional information, refer to Skyworks The SKY65943-11 uses surface-mount technology (SMT) in the TM Denition of Green , document number form of a 2.5 x 2.5 mm Multi-Chip Module (MCM) package, which SQ040074. allows for a highly 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.
