4-Section GPS L1 Bandpass Filter (1.565 GHz – 1.585 GHz)

Service Description

End Product

This 4-section bandpass filter is a high-performance solution specifically engineered for GPS L1 band applications. Operating within a precise frequency range of 1.565 GHz to 1.585 GHz, it provides a focused 20 MHz passband to ensure signal integrity and minimize interference in critical navigation and communication systems.

Utilizing an advanced design, this filter delivers exceptional selectivity and out-of-band rejection. It achieves a robust 50 dB rejection at 1.475 GHz and 1.675 GHz (approximately 90 MHz from the band edges), effectively isolating the desired signals from surrounding noise. With a typical insertion loss of only 1.5 dB, it maintains high efficiency for sensitive RF front-ends.
