Description
The SKY65943-11 is a front-end module (FEM) with an integrated
low-noise amplifier (LNA) and pre-filter and post-filter designed
for Global Navigation Satellite System (GNSS) receiver
applications. The device provides high gain, excellent out-of-band
rejection, and low noise figure. The pre-filter and post-filter
provide low in-band insertion loss and excellent rejection for the
cellular, PCS, and WLAN frequency bands. Output matching
components are embedded inside the device. Only one external
input matching inductor is required.
The SKY65943-11 is optimized to operate at 1559 to 1606 MHz,
which makes it ideal for GPS/GLONASS/Galileo/Compass/QZSS
radio receiver applications.
The SKY65943-11 uses surface-mount technology (SMT) in the
form of a 2.5 x 2.5 mm Multi-Chip Module (MCM) 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.

1 Exposure to maximum rating conditions for extended periods may reduce device reliability. 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.
