LFD182G45DCJD949

RF Multiplexers Overview

The LFD182G45DCJD949 is a SAW duplexing diplexer manufactured by Murata Electronics, designed to separate low and high frequency bands. It operates with a center frequency of 2450.00MHz for the lower band (2400.00MHz to 2500.00MHz) and 5425.00MHz for the upper band (4900.00MHz to 5950.00MHz). The device features low insertion loss, rated at 0.40dB max at 25°C and 0.50dB max across -40°C to +85°C for the first port. For the second port, insertion loss is 0.50dB max at 25°C and 0.60dB max over the temperature range. VSWR is limited to 1.50 max across all ports. It supports a permissible power of 3W and functions within a temperature range of -40°C to 85°C. The component measures 1.60mm x 0.80mm with a maximum thickness of 0.7mm.
