Ultra Low Profile 0805 Balun
50 to 50 Balanced
 
 
Description
 
 
 
 
 
 
 
  The B0322J5050AHF 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
frequency. The B0322J5050AHF is ideal for high volume manufacturing and is
higher performance than traditional ceramic and lumped element baluns. The
B0322J5050AHF has an unbalanced port impedance of 50& and a 50& 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 B0322J5050AHF is available on tape
and reel for pick and place high volume manufacturing.
