Model BD2425J50200A00

Rev B

Ultra Low Profile 0805 Balun

50Ω to 200Ω Balanced

Description

The BD2425J50200A00 is a low profile sub-miniature balanced to unbalanced

transformer designed for differential inputs and output locations on next generation

wireless chipsets in an easy to use surface mount package covering the GSM

frequencies. The BD2425J50200A00 is ideal for high volume manufacturing and is

higher performance than traditional ceramic and lumped element baluns. The

BD2425J50200A00 has an unbalanced port impedance of 50

Ω and a 200Ω

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 BD2425J50200A00 is

available on tape and reel for pick and place high volume manufacturing.
