Product Overview

The LFB182G45CGFD436 is a high-performance 2.45GHz bandpass filter launched by Murata, designed specifically for wireless communication devices requiring high anti-interference capabilities. With a precise center frequency of 2450.00MHz and a passband range of fo±50.00MHz, it achieves low insertion loss (max 2.6dB at 25℃) and extreme out-of-band attenuation—attenuation ≥40dB in the 0~1610MHz band and ≥38dB in the 1710~1785MHz band, deeply filtering interfering signals across multiple frequency bands. Adopting an ultra-miniature SMD package of 1.6×0.8×0.65mm, it features an impedance match of 50Ω, in-band Voltage Standing Wave Ratio (VSWR) ≤1.7, power handling capacity of 500mW, and an operating temperature range of -40℃~+85℃. It is a core component for signal purification in 2.4GHz band Wi-Fi, Bluetooth, and IoT devices.
