The LFB182G45BG2D280 has been designed specifically for use with wireless connectivity SoCs from Texas Instruments, in particular the CC253x and CC254x.
The new device measures just 1.6 x 0.8mm, and according to Murata 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 is said to replace 9 discrete 0402 components and offer improved spurious emissions.
In addition, the LFB182G45BG2D280 has an unbalanced port impedance of 50ohm and a frequency range of 2,450 down to 50MHz. Power capacity is rated at 500mW maximum.
