Model FB2425E50100A00
Rev A
Ultra Low Profile Filter Balun
50Ω to 100Ω Balanced
Description
The FB2425E50100A00 is a low cost, low profile sub-miniature unbalanced to
balanced transformer designed for differential inputs and output locations on next
generation wireless chipsets in an easy to use surface mount package covering
wireless LAN (802.11b/g/n) and Bluetooth frequencies (2400 MHz – 2500 MHz).
The FB2425E50100A00 is ideal for high volume manufacturing and is in a lower
profile unit than traditional ceramic parts. The FB2425E50100A00 has an
unbalanced port impedance of 50Ω and a 100Ω balanced port impedance. This
transformation enables single ended signals to be applied to differential ports on
modern semiconductors. The output ports have equal amplitude (-3dB) with 180
degree phase differential. The FB2425E50100A00 is available on tape and reel for
high volume pick and place manufacturing.

The internal configuration of the Ultra low profile filter balun is
diagramed to the left. A lumped element filter is located in front of the
unbalanced input of the balun. The unbalanced port is terminated in an
open-circuit and the two balanced ports are connected to ground.
The use of differential circuits is increasing in highly integrated
circuits, because of its inherent noise immunity properties. Differential
circuits have superior performance when looking at properties like cross
coupling, immunity to external noise sources and power supply noise.
When designing power amplifiers differential circuits also help minimize
2^nd and 3^rd order intermodulation products.
The construction of the filter balun is bonded multi-layered
stripline made of low loss dielectric material with plated through vias
connecting the internal circuitry to the external printed circuit board,
similar to that of the other hybrids and directional couplers
