Once port one has been identified the other ports are known automatically.

When two quadrature signals with equal amplitudes are applied to the coupler as described in the table, they will combine at the output port. If the amplitudes are not equal, some of the applied energy will be directed to the isolated port. The actual phase, ∠θ, or amplitude at a given frequency for all ports, can be seen in our de-embedded sparameters, that can be downloaded at www.ttm.com. Peak Power Handling High-Pot testing of these couplers during the qualification procedure resulted in a minimum breakdown voltage of 1.31Kv (minimum recorded value). This voltage level corresponds to a breakdown resistance capable of handling at least 12dB peaks over average power levels, for very short durations. The breakdown location consistently occurred across the air interface at the coupler contact pads (see illustration below). The breakdown levels at these points will be affected by any contamination in the gap area around these pads. These areas must be kept clean for optimum performance. It is recommended that the user test for voltage breakdown under the maximum operating conditions and over worst case modulation induced power peaking. This evaluation should also include extreme environmental conditions (such as high humidity). 2 X3C19P2-03S Rev G Insertion Loss and Power Derating Curves X3C19P2-03 Power Derating Curve 350 300 1700 - 2000 MHz, 1805 1880 MHZ, 1930 - 1990 MHz Bands 1800 - 2200 MHz Band Power (Watts) 250 200 176 150 145 120 100 50 0 0 50 95 100 105 150 200 Mounting Interface Temperature (oC) Insertion Loss Derating: Power Derating: The insertion loss, at a given frequency, of a group of couplers is measured at 25°C and then averaged. 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 300°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 95°C, Xinger coupler will perform reliably as long as the input power is derated to the curve above. 3 X3C19P2-03S Rev G Typical Performance (-55°C, 25°C, 95°C & 105°C): 1600-2300 MHz Return Loss for X3C19P2-03S (Feeding Port 1) 0 -55ºC 25ºC 95ºC 105ºC -10 Return Loss (dB) Return Loss (dB) -10 -20 -30 -20 -30 -40 -40 -50 1600 1700 1800 2000 1900 Frequency (MHz) 2100 2200 1700 -30 -40 2000 1900 Frequency (MHz) 2100 2200 2300 -55ºC 25ºC 95ºC 105ºC -10 Return Loss (dB) -20 1800 Return Loss for X3C19P2-03S (Feeding Port 4) 0 -55ºC 25ºC 95ºC 105ºC -10 -50 1600 -50 1600 2300 Return Loss for X3C19P2-03S (Feeding Port 3) 0 Return Loss (dB) Return Loss for X3C19P2-03S (Feeding Port 2) 0 -55ºC 25ºC 95ºC 105ºC -20 -30 -40 1700 1800 1900 2000 Frequency (MHz) 2100 2200 2300 -50 1600 1700 1800 1900 2000 Frequency (MHz) 2100 2200 2300 4 X3C19P2-03S Rev G Coupling for X3C19P2-03S (Feeding Port 1) -2.5 -55ºC 25ºC 95ºC 105ºC -2.6 -2.7 Isolation for X3C19P2-03S (Feeding Port 1) 0 -55ºC 25ºC 95ºC 105ºC -10 -2.9 Isolation (dB) Coupling (dB) -2.8 -3 -3.1 -20 -30 -3.2 -40 -3.3 -3.4 -3.5 1600 0 -50 1600 1700 1800 1900 2000 Frequency (MHz) 2100 2200 1700 1800 2300 Insertion Loss for X3C19P2-03S (Feeding Port 1) 2000 1900 Frequency (MHz) 2300 2200 2100 Phase Balance for X3C19P2-03S (Feeding Port 1) -55ºC 25ºC 95ºC 105ºC -0.1 -55ºC 25ºC 95ºC 105ºC 4 Phase Balance (deg) Insertion Loss (dB) 2 -0.2 -0.3 0 -2 -0.4 -4 -0.5 1600 1700 1800 1900 2000 Frequency (MHz) 2100 2200 2300 1600 1700 1800 1900 2000 Frequency (MHz) 2100 2200 2300 5 X3C19P2-03S Rev G Definition of Measured Specifications Parameter Definition VSWR (Voltage Standing Wave Ratio) The impedance match of the coupler to a 50Ω system.
