LFCG-3800+

Ceramic Low Pass Filter 50Ω LFCG-3800+ DC to 3900 MHz The Big Deal • Very good rejection, 50 dB typical • Rugged, ceramic construction • Tiny size, 0.079 x 0.049 x 0.037” (0805) • Excellent power handling, 6W Generic photo used for illustration purposes only CASE STYLE: GE0805C-2 Product Overview Mini-Circuits’ LFCG-3800+ is an LTCC low pass filter with a passband from DC to 3900 MHz, supporting a variety of applications. This model provides 1.3 dB typical passband insertion loss and provides a very good stopband rejection due to strategically constructed layout with minimal interaction between components. It handles up to 6W RF input power and provides a wide operating temperature range from -55 to +100°C. Housed in a tiny 0805 ceramic form factor with wraparound terminations, the filter is ideal for dense PCB layouts and with minimal performance variation due to parasitics. Key Features Feature Advantages Ultra-wide stopband The LTCC lowpass filter provides a very good stopband rejection until 18 GHz suitable for high end applications. LTCC Construction Provides repeatable performance in a rugged, ceramic package well suited for tough environments such as high humidity and temperature extremes. Tiny size (0.079 x 0.049 x 0.037”) Saves space in dense circuit board layouts and minimizes the effects of parasitics. High power handling, 6W Supports a wide range of system power requirements. Wrap-around terminations Provides excellent solderability and easy visual inspection Notes A.
