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 85C and no DC-bias and is based on a maximum operating temperature of the part itself of 125C (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 10 PRF , diss Pin 1 10 1 10 10 [W ] 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 125C. When used with DC-biasing the RF-power must be de-rated with the amount of DC power dissipated; Pdc, diss Rout1 || Rout 2 I dc2 7 I dc2 [W ] The total dissipated power cannot exceed 0.5watts. When the duty cycle is not 100% the input power can be averaged, however the instantaneous input power should newer exceed 0.5watts.

Model B0110E50200AHF Rev C Mounting Configuration: In order for Xinger surface mount components to work optimally, the proper impedance transmission lines must be used to connect to the RF ports. 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. To supply common mode voltage offset to the analog-to-digital converter, DC blocking capacitors are needed at the balanced port (pins 6 & 8). 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. In addition, two external 0402 capacitors must be mounted in locations C1 and C2 as shown in the figure below to get the performance specified in the datasheet. .06 Plated thru hole(s) to Ground 0402 Capacitor .06 0402 Capacitor Part Orientation (Top View) 4x .22 10x .28 3x Transmission Line 6x .29 10x .36 4x .15 Circuit Pattern Footprint Pad(s) Solder Resist External Component Footprint Dimensions are in millimeters Available on Tape and Reel for Pick and Place Manufacturing.
