Model 0922B75-37A
Rev. A
Xinger Balun
75Ω to 75Ω Balanced
Description
The 0922B75-37A is a low cost, low profile sub-miniature unbalanced to
balanced transformer designed for differential inputs and output locations on
wireless chipsets in an easy to use surface mount package covering dual polarized
commercial Satellite bands 950 MHz – 2150 MHz. The 0922B75-37A is ideal for
high volume manufacturing and is higher performance than traditional wire wound
baluns. The 0922B75-37A has an unbalanced port impedance of 75Ω and a 75Ω
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 0922B75-37A is
available on tape and reel for pick and place high volume manufacturing.
