REV A

Nano Profile 0404 Balun

to 100

Balanced

Description

The BD2425P50100AHF is a low cost, nano profile sub-miniature unbalanced

to balanced transformer designed for differential inputs and output locations on

modern

chipsets

in

an

easy

to

use

surface

mount

package.

The

BD2425P50100AHF has been developed for placement inside highly integrated,

over moldable packaging solutions where overall module height is of greatest

concern. Ideal for high volume manufacturing and delivers higher performance than

traditional ceramic baluns in a sub 0.5mm height profile. The BD2425P50100AHF

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 integrated chipsets. The output ports have equal amplitude (-3dB) with

180 degree phase differential. The BD2425P50100AHF is available on tape and reel

for pick and place high volume manufacturing.
