In this paper, fully embedded and miniaturized diplexer device has been developed and characterized for dual-band/mode CDMA handset applications. The size of the embedded diplexer is significantly reduced by embedding high Q circular spiral inductors and high DK MIM capacitors into a low cost organic package substrate. The fabricated diplexer has insertion losses and isolations of -0.5 and -23㏈ at 824-894㎒ and -0.7 and -22㏈ at 1850-1990㎒, respectively. Its size is 3.9㎜ × 3.9㎜ × 0.77㎜ (height). The fabricated diplexer is the smallest one which is fully embedded into a low cost organic package substrate.

In this paper, embedded spiral inductors are investigated into the PCB substrate for low cost RF SOP applications. The spiral inductors designed with geometrical variations were simulated, fabricated, measured, and characterized by using 3D EM simulator, 8 layered PCB standard process and HP 8510B network analyzer for verifying their applicability. The fabricated embedded spiral inductor has inductance of 9.4nH at 800㎒, maximum quality factor of 64.8 at 1.09㎓ and self resonant frequency of 3.93㎓, respectively. As the measured inductances and quality factors are well matched with simulated ones. PCB embedded spiral inductors are promising for advanced electronic systems with various functionality, low cost, small size and volume.
