Murata launches world’s smallest 2.4 GHz balanced output filter for Texas Instruments wireless connectivity solutions

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. This tiny six-pin space saving device ensures board space, BOM count and engineering effort is kept to a minimum. Compared with a traditional inductor and capacitor design, the LFB module replaces 9 discrete 0402 components.

Compared to the original reference design, spurious emissions are improved by 11dB. Also, harmonic performance is 20dB better at 2xfc and 3xfc.
The LFB182G45BG2D280 device has an unbalanced port impedance of 50 ohm and a frequency range of 2,450 MHz +/- 50 MHz. It has a power capacity of up to 500 mW maximum.
