B0225J7575AHF

* B0225J7575AHF Rev E Ultra Low Profile 0805 Balun 75Ω to 75Ω Balanced Description: The B0225J7575AHF 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 DVB-T, DVB-C and DVB-S broadcast frequencies. The B0225J7575AHF is ideal for high volume manufacturing and is higher performance than traditional wire wound and lumped element baluns. The B0225J7575AHF 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. The output ports have equal amplitude (3dB) with 180 degree phase differential. The B0225J7575AHF is available on tape and reel for pick and place high volume manufacturing.

If this condition is not satisfied, insertion loss, Isolation 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. 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. Circuit Pattern Dimensions are in Millimeters Mounting Footprint Footprint Pad (s) Solder Resist 6x .41 4x .25 Plated thru holes to ground .04 6x .33 3x Transmission lines .66 4 B0225J7575AHF Rev E Packaging and Ordering Information: Parts are available in reel and are packaged per EIA 481-2.
