This is LGE, F4109 SAW Filter. A SAW filter, also known as a Surface Acoustic Wave filter, is an electronic component used in communication systems to filter and shape electrical signals based on the principle of surface acoustic wave propagation.

1. Filter Operation: SAW filters utilize surface acoustic waves generated on a piezoelectric substrate, typically made of quartz or lithium niobate. These waves propagate along the surface of the substrate, allowing for effective filtering of electrical signals.

2. Frequency Selectivity: SAW filters offer high selectivity and can provide precise frequency response characteristics. They are capable of filtering out unwanted frequencies and allowing only desired frequencies to pass through.

The LGEF4109 is a low-loss, compact, and economical surface-acoustic-wave (SAW) RF filter in a surface-mount ceramic QCC8D case with center frequency 433.920 MHz.
