Ceramic Low Pass Filter LFCW-123+ 50 DC to 12 GHz The Big Deal Good rejection, 38 dB typical Generic photo used for illustration purposes only Rugged, ceramic construction CASE STYLE: JC0603C-1 Tiny size, 0.063 x 0.032 x 0.024 (0603) Good power handling, 4W Product Overview Mini-Circuits LFCW-123+ is an LTCC low pass filter with a passband from DC to 12 GHz, supporting a variety of ap - plications. 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 4W RF input power and provides a wide operating temperature range from -55 to +100C. 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 The LTCC lowpass filter provides a very good stopband rejection until 26.5 GHz suitable for high Ultra-wide stopband end applications. Provides repeatable performance in a rugged, ceramic package well suited for tough environments LTCC Construction 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, 4W Supports a wide range of system power requirements. Wrap-around terminations Provides excellent solderability and easy visual inspection Notes A.
