The LFCN-1575D from Mini-Circuits is a Space-Qualified Low-Pass RF Filter engineered for high-reliability applications operating over a DC–1575 MHz frequency range. This precision filter provides a passband insertion loss of just 1 dB and delivers strong stopband rejection of 20–40 dB, ensuring clean signal filtering and effective suppression of unwanted harmonics.
Designed for optimal RF performance, the LFCN-1575D maintains an excellent passband VSWR of 1.2:1 and a stopband VSWR of 20:1. It offers a 3 dB cutoff frequency at 1825 MHz and supports up to 10 W RF input power, making it suitable for demanding transmitter and receiver systems. The filter can handle a maximum DC voltage of 25 V and 0.5 A DC current, adding flexibility for integration into various RF platforms.
Constructed using LTCC (Low Temperature Co-fired Ceramic) technology, this RoHS-compliant, hermetically sealed ceramic filter provides exceptional durability in harsh space environments while weighing only 0.02 g. Its compact, rugged design making the filter ideal for harmonic rejection, VHF/UHF transmitters and receivers, and laboratory test setups requiring stable, space-grade filtering performance.
