LFCW-8400+

Ceramic Low Pass Filter 50Ω LFCW-8400+ DC to 8.4 GHz The Big Deal • Very good rejection, 45 dB typical • Rugged, ceramic construction • Tiny size, 0.063” x 0.032” x 0.024” (0603) • Good power handling, 2.5W Generic photo used for illustration purposes only CASE STYLE: JC0603C-1 Product Overview Mini-Circuits’ LFCW-8400+ is an LTCC low pass filter with a passband from DC to 8.4 GHz, supporting a variety of applications. This model provides 1.2 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 2.5W RF input power and provides a wide operating temperature range from -55 to +125°C. Housed in a tiny 0603 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 26.5 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 ( 0.063” x 0.032” x 0.024”) Saves space in dense circuit board layouts and minimizes the effects of parasitics. Good power handling, 2.5W Supports a wide range of system power requirements. Wrap-around terminations Provides excellent solderability and easy visual inspection Notes A.
