Product Overview

The LFB152G45CB2D320 is a high-performance 2.45GHz bandpass filter launched by Murata, designed specifically for signal filtering in wireless communication systems. With a precise center frequency of 2450MHz, wide passband range of ±50MHz, and wide operating temperature range of -40℃~+85℃, it achieves low insertion loss (max 1.5dB at 25℃) and high attenuation across multiple frequency bands, with an impedance match of 50Ω, Voltage Standing Wave Ratio (VSWR) ≤2.1, and maximum power handling capacity of 500mW. Adopting an ultra-miniature SMD package of 1.00×0.50×0.40mm, it features a compact structure and high reliability, making it a core signal processing component for 2.4GHz band wireless devices such as Wi-Fi, Bluetooth, and Internet of Things (IoT) devices.
