LFCG-2850+

Ceramic Low Pass Filter 50Ω LFCG-2850+ DC to 2850 MHz The Big Deal • Very good rejection, 45 dB typical • Rugged, ceramic construction • Tiny size, 0.079" x 0.049" x 0.037" (0805) • Excellent power handling, 4.5W Generic photo used for illustration purposes only CASE STYLE: GE0805C-2 Product Overview Mini-Circuits’ LFCG-2850+ is an LTCC low pass filter with a passband from DC to 2850 MHz, supporting a variety of applications. This model provides 0.9 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 4.5W RF input power and provides a wide operating temperature range from -55°C to 125°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 Very good stopband rejection, 45 dB typical The LTCC lowpass filter provides a very good stopband rejection until 14 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, 4.5W Supports a wide range of system power requirements. Wrap-around terminations Provides excellent solderability and easy visual inspection Notes A.
