The measurements are performed under small signal conditions (i.e. using a Vector Network Analyzer). The process is repeated at 85°C and 150°C. A best-fit line for the measured data is computed and then plotted from -55°C to 150°C. The power handling and corresponding power derating plots are a function of the thermal resistance, mounting surface temperature (base plate temperature), maximum continuous operating temperature of the coupler, and the thermal insertion loss. The thermal insertion loss is defined in the Power Handling section of the data sheet. As the mounting interface temperature approaches the maximum continuous operating temperature, the power handling decreases to zero. If mounting temperature is greater than 85°C, Xinger coupler will perform reliably as long as the input power is derated to the curve above.

A VSWR of 1:1 is optimal. Return Loss Mean Coupling Insertion Loss Transmission Loss Directivity Frequency Sensitivity Mathematical Representation The impedance match of the coupler to a 50Ω system. Return Loss is an alternate means to express VSWR. At a given frequency (ωn), coupling is the input power divided by the power at the coupled port. Mean coupling is the average value of the coupling values in the band. N is the number of frequencies in the band. The input power divided by the sum of the power at the two output ports. The input power divided by the power at the direct port. The power at the coupled port divided by the power at the isolated port. The decibel difference between the maximum in band coupling value and the mean coupling, and the decibel difference between the minimum in band coupling value and the mean coupling. VSWR = Vmax Vmin Vmax = voltage maxima of a standing wave Vmin = voltage minima of a standing wave Return Loss (dB)= 20log VSWR + 1 VSWR - 1  Pin (ωn )      Pcpl (ωn )  Coupling (dB) = C (ωn ) = 10 log N Mean Coupling (dB) = 10log ∑ C (ω n =1 n ) N Pin Pcpl + Pdirect 10log 10log Pin Pdirect Pcpl Piso Max Coupling (dB) – Mean Coupling (dB) and Min Coupling (dB) – Mean Coupling (dB) Available on Tape and Reel For Pick and Place Manufacturing.

Also, there must be a very good ground plane underneath the part to ensure proper electrical performance. If either of these two conditions is not satisfied, electrical performance may not meet published specifications. The process for assembling this component is a conventional surface mount process as shown in Figure 1. This process is conducive to both low and high volume usage. Overall ground is improved if a dense population of plated through holes connect the top and bottom ground layers of the PCB. This minimizes ground inductance and improves ground continuity. All of the Xinger hybrid and directional couplers are constructed from ceramic filled PTFE composites which possess excellent electrical and mechanical stability. When a surface mount hybrid coupler is mounted to a printed circuit board, the primary concerns are; ensuring the RF pads of the device are in contact with the circuit trace of the PCB and insuring the ground plane of neither the component nor the PCB is in contact with the RF signal. Mounting Footprint To ensure proper electrical and thermal performance there must be a ground plane with 100% solder connection underneath the part Figure 1: Surface Mounting Process Steps Storage of Components: Xinger products are available in an immersion tin finish. Commonly used storage procedures used to control oxidation should be followed for these surface mount components. The storage temperatures should be held between 15OC and 60OC. Substrate: Depending upon the particular component, the circuit material has a coefficient of thermal expansion (CTE) similar to commonly used board substrates such as RF35, RO4003, FR4, polyimide and G-10 materials. The similarity in CTE minimizes solder joint stresses due to similar expansion rates between component and board. Mounting to “hard” substrates (alumina etc.) is possible depending upon operational temperature requirements. The solder surfaces of the coupler are all copper plated with an immersion tin exterior finish. Solder Paste: All conventional solder paste formulations will work well with Anaren’s Xinger surface mount components. Solder paste can be applied with stencils or syringe dispensers. An example of a stenciled solder paste deposit is shown in Figure 2. As shown in the figure solder paste is applied to the four RF pads and the entire ground plane underneath the body of the part. .170 [4.32] Multiple plated thru holes to ground .120 [3.05] 4X .034 [0.86] 4X .063 SQ [1.60] 4X 50  Transmission Line Dimensions are in Inches [Millimeters] 1P620* Rev A Mounting Footprint USA/Canada: Toll Free: Europe: Asia: (315) 233-5510 (833) 389-6402 +44 2392-232392 +86 512 62749282 Available on Tape and Reel For Pick and Place Manufacturing. Model 1P620S Rev E Reflow: The surface mount coupler is conducive to most of today’s conventional reflow methods. A low and high temperature thermal reflow profile are shown in Figures 5 and 6, respectively. Manual soldering of these components can be done with conventional surface mount non-contact hot air soldering tools. Board pre-heating is highly recommended for these selective hot air soldering methods. Manual soldering with conventional irons should be avoided. Figure 2: Solder Paste Application Coupler Positioning: The surface mount coupler can be placed manually or with automatic pick and place mechanisms. Couplers should be placed (see Figure 3 and 4) onto wet paste with common surface mount techniques and parameters. Pick and place systems must supply adequate vacuum to hold a 0.106 gram coupler.
