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, 6W
CASE STYLE: GE0805C-2
Product Overview
Mini-Circuits’ LFCG-1000+ is an LTCC low pass filter with a passband from DC to 1000 MHz, supporting a variety of
applications. This model provides 0.8 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 -40°C to 85°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
The LTCC lowpass filter provides a very good stopband rejection until 10 GHz suitable for high end
typical
applications.
Provides repeatable performance in a rugged, ceramic package well suited for tough environments
such as high humidity and temperature extremes.
