B0011E75300A00

Model B0011E75300A00 Rev B Ultra Low Profile 1008 Balun 75Ω to 300Ω Balanced Description The B0011E75300A00 is a low profile sub-miniature balanced to unbalanced transformer designed for differential inputs and output locations on next generation analog and digital TV chipsets in an easy to use surface mount package. The B0011E75300A00 is ideal for high volume manufacturing and is higher performance than traditional wire wound baluns. The B0011E75300A00 has an unbalanced port impedance of 75Ω and a 300Ω 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 B0011E75300A00 is available on tape and reel for pick and place high volume manufacturing. Detailed Electrical Specifications: Specifications subject to change without notice.

This improves the insertion loss, return loss and balanced performance in the 870-1080MHz range. This inductance can be realized as a transmission line (dimensions will depend on the PCB material and ground plane distance). The added inductance can be used in conjunction with the external capacitors. When mounted with high groundplane spacing, part of this inductance comes automatically from the increased inductance of the typical via to ground. 9 9 9 Figure 5 Biasing the balanced signals thru the balun. Dependign on the quality of “C3” the additional capacitor “C4” may not be needed. The DC-resistance from the bias point thru to each of the outputs are 10±4Ω. It is important to keep inductance to a minimum from pin 5 to ground or balanced performance will suffer. When used with high groundplane spacings it is recommended to have two or more via to ground. 11 11 Port_1 ZO=75Ω [=Zin] 2 C1 C=82pF 6 6 10 4 B0011E75300Axx 1 Port_3 ZO=150Ω [=Zout/2] 4 3 3 5 7 R1 R=300 Ω [Zout] 5 12 12 9 Figure 6 Using the balun as an single ended to single ended impedance transformer (Unun). Pin 5 must be open circuit. It is recommended to use the 82pF on the low impedance side to improve the insertion loss and return loss in the 50-200MHz range. Note that pins 4 & 7 can only be interchanged if pins 9 7 10 are also interchanged, otherwise performance will suffer. Available on Tape and Reel for Pick and Place Manufacturing.

Very, very low levels of distortion can arise from dissimilar metals on the contact pads of the part (Cu-Ni-Au) and from inter-metallic contaminations within the part. Power Handling Considerations: The RF-power handling capability of these baluns depends on the temperature at the mounted interface (base plate temperature), and whether or not DC-bias is feed through the part. The power handling specified is for a mounted temperature of 85˚C and no DC-bias and is based on a maximum operating temperature of the part itself of 125˚C (do not exceed this). The maximum power handling relates to the dissipated power within the part and is therefore a function of insertion loss. The insertion loss of this device changes within the specified band. Thus if operated with a narrowband signal at either band edge (this is what is specified) it will have less power handling than if operated closer to the center of the band or if operated with a very wideband signal. If signals arrive at the balun that are out of the specified band, these must be included in the total dissipated power calculation. However the deteriorating return loss will eliminate some of this power. The dissipated RF power can be estimated as;  RL   IL   −  dB   −  dB   1 − 10  10  1 − 10  10   [W ] PRF , diss = Pin       Where: • Pin is the input power, either on the low impedance side, single ended or the combined differential power on the balanced side, depending on the feeding direction. • RLdB is the return loss in dB associated with the feeding port. I.e. if feed from the balanced side then the balanced return loss must be used (this however is very similar to the single ended return loss). • ILdB is the insertion loss at the operating temperature of the device. Below the dissipated power is shown at a normalized 1W input power for the balun internal temperature of 125˚C.

If this condition is not satisfied, insertion loss, Isolation and VSWR may not meet published specifications. All of the Xinger components are constructed from softboard composites which possess excellent electrical and mechanical stability having X and Y thermal coefficient of expansion (CTE) of 19 ppm/oC. 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. .026 [0.65] 10X .014 [0.35] .018[0.46] 3X Transmission Line Component Top View .026 [0.65] .068 [1.73] Circuit Pattern Footprint Pad (s) Solder Resist Dimensions are in Inches [Millimeters] Mounting Footprint .021 [0.54] 10X .011 [0.27] The material used for testing is 8mil Rogers 4003.
