Additional Details

The SKY65384 is designed to operate at the frequencies of the various GNSS systems it supports (e.g., 1575.42 MHz for GPS L1). The LNA is typically designed for a low noise figure (e.g., less than 1 dB) and provides a gain of around 15-20 dB. The SAW filter offers excellent rejection of out-of-band signals, preventing interference from affecting the receiver's performance. Specific electrical characteristics such as gain, noise figure, insertion loss, and return loss can be found in the manufacturer's datasheet. Proper impedance matching to the antenna and receiver is crucial for optimal performance. The component is designed for reflow soldering and is supplied in tape and reel packaging.
