2,4 GHz output filter

9 November 2011 Telecoms, Datacoms, Wireless, IoT

Murata’s new LFB182G45BG2D280 is a balanced output matching filter aimed at a broad range of 2,4 GHz wireless applications using ZigBee and Bluetooth low energy technologies.

The new filter has been designed specifically for use with wireless connectivity system-on-chips (SoCs) from Texas Instruments, the CC253x and CC254x for ZigBee and Bluetooth technology networking respectively. Believed to be the world’s smallest filter available, Murata’s solution measures just 1,6 x 0,8 mm and incorporates all the necessary RF circuitry of a matching network, balun and filter within a single package. Compared with a traditional inductor and capacitor design, the LFB module replaces nine discrete 0402 components.

The LFB182G45BG2D280 has an unbalanced port impedance of 50 Ω and a frequency range of 2,450 MHz ±50 MHz. It has a power capacity of up to 500 mW.
