LFCV-45+

Low Pass Filter 50Ω LFCV-45+ DC to 45 MHz The Big Deal: • Small size 3.2mm x 2.5 mm • High Power handling (8W) • High rejection (50 dB typ) • Ceramic construction Product Overview: CASE STYLE: JV1210C New Low Pass Filter LFCV-45+ is an LTCC based 7 section design, that extends the lower frequency cutoff range of the existing LFCN series to 45 MHz. Systems that previously relied on active or lumped element filtering to support these lower frequencies can save power and system complexity by integrating the LFCV-45+ into new designs. These filters are offered in a EIA 1210 package size and have a typical stop band rejection of 50 dB. Summary Performance Insertion Loss (Pass band) 1.2 dB Max. 45 MHz Return Loss (Pass band) 20 dB Typ. 45 MHz Stop band Rejection 20 dB Min. 120 MHz Stop band Rejection 50 dB typ. 180 MHz Key Features Feature Advantages Small Size (3.2mm x2.5 mm) Available in the size of typical resistors or capacitors (EIA 1210), the ultra small LFCV series integrates up to 7 low pass sections in a simple SMT chip form factor. High Power Handling The LFCV series can withstand up to 8W CW signal without damage making this filter ideal for use in medium power to transmit paths. Temperature Stability Over a 155°C operating temperature range (-55°C to +100°C), the LFCV series ceramic filters typically exhibit less than 0.2 dB pass band insertion loss variation, and less than 0.4 dB rejection variation at the 20 dB point (as measured on a single unit) High Rejection Achieving 50dB rejection @180 MHz; the LFCV-45+ provides a versatile anti aliasing solution for high data rate receivers.
