GNSS Low-Noise Amplifier Front-End Modules: SKY65933-11, SKY65943-11
Skyworks offer two new front-end modules (FEMs) for GNSS/GPS/GLONASS/Galileo/Compass/QZSS radio receiver applications in the 1559 to 1606 MHz frequency range. The SKY65933-11 and the SKY65943-11 feature an integrated low noise amplifier (LNA), and a pre-filter and post-filter. Both devices use 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.
The SKY65933-11 fully integrates all input and output matching components to simplify PCB designs. The pre-filter and post-filter provide low in-band insertion loss and excellent rejection for the cellular, PCS, and WLAN frequency bands. The device also features a single-pin enable and an extremely low shut-down current when disabled.
The SKY65943-11 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.
