B0922J7575AHF

B0922J7575AHF Rev C Ultra Low Profile 0805 Balun 75Ω to 75Ω Balanced Description: The B0922J7575AHF is a low cost, low 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 covering dual polarized commercial Satellite bands 950 MHz –1450 MHz & 1650 MHz – 2150 MHz. The B0922J7575AHF is ideal for high volume manufacturing and delivers higher performance than traditional wire wound baluns. The B0922J7575AHF 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 B0922J7575AHF is available on tape and reel for pick and place high volume manufacturing.

If this condition is not satisfied, insertion and VSWR may not meet published specifications. All of the Xinger components are constructed from organic PTFE based composites which possess excellent electrical and mechanical stability. Xinger components are compliant to a variety of ROHS and Green standards and ready for Pb-free soldering processes. Pads are Gold plated with a Nickel barrier. An example of the PCB footprint used in the testing of these parts is shown below. An example of a DC-biased footprint is also shown below. In specific designs, the transmission line widths need to be adjusted to the unique dielectric coefficients and thicknesses as well as varying pick and place equipment tolerances. 4x .25 6x .41 6x .33 .66 .04 3x Transmission lines 2x Plated thru holes to ground Circuit Pattern Footprint Pad (s) Solder Resist Dimensions are in Millimeters Mounting Footprint 3 B0922J7575AHF Rev C Packaging and Ordering Information: Parts are available in reel and are packaged per EIA 481-2.
