X3C09E2-20S Rev D 20 dB Directional Coupler Description: The X3C09E2-20S is a low profile, high performance 20dB directional coupler in a new easy to use, manufacturing friendly surface mount package. It is designed for AMPS, GSM, WCDMA and LTE band applications. The X3C09E2-20S is designed particularly for power and frequency detection, as well as for VSWR monitoring, where tightly controlled coupling and low insertion loss is required. It can be used in high power applications up to 225 Watts. Parts have been subjected to rigorous qualification testing and they are manufactured using materials with coefficients of thermal expansion (CTE) compatible with common substrates such as FR4, G-10, RF-35, RO4003 and polyimide.

Once port one has been identified the other ports are known automatically. Please see the chart below for clarification: Pin 1 Input Direct Pin 2 Direct Input Pin 3 Isolated Coupled Pin 4 Coupled Isolated Note: The direct port has a DC connection to the input port and the coupled port has a DC connection to the isolated port. For optimum IL and power handling performance, use Pin 1 or Pin 2 as inputs. Peak Power Handling: High-Pot testing of these couplers during the qualification procedure resulted in a minimum breakdown voltage of 1.50kV. 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 X3C09E2-20S Rev D Typical Insertion Loss Derating Curve for X3C09E2-20 0 typical insertion loss (f=800Mhz) typical insertion loss (f=894Mhz) typical insertion loss (f=960Mhz) typical insertion loss (f=1000Mhz) -0.01 Insertion Loss (dB) -0.02 -0.03 -0.04 -0.05 -0.06 -100 -50 0 50 100 150 200 o Temperature of the Part ( C) Insertion Loss 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 150°C. Power Derating: 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 X3C09E2-20S Rev D Typical Performance: (-55°C, 25°C and 95°C): 700-1000 MHz Return Loss for X3C09E2-20S(Feeding port1) 0 25ºC -55ºC 95ºC -10 -20 Return Loss (dB) Return Loss (dB) 25ºC -55ºC 95ºC -10 -20 -30 -40 -30 -40 -50 -50 -60 -60 -70 700 Return Loss for X3C09E2-20S(Feeding port2) 0 750 800 850 Frequency (Mhz) 900 950 -70 700 1000 Return Loss for X3C09E2-20S(Feeding port3) 0 750 850 Frequency (Mhz) 900 950 25ºC -55ºC 95ºC -10 -10 1000 Return Loss for X3C09E2-20S(Feeding port4) 0 25ºC -55ºC 95ºC 800 -20 Return Loss (dB) Return Loss (dB) -20 -30 -30 -40 -40 -50 -50 -60 700 -60 750 800 850 Frequency (Mhz) 900 950 1000 -70 700 750 800 850 Frequency (Mhz) 900 950 1000 4 X3C09E2-20S Rev D Typical Performance: (-55°C, 25°C and 95°C): 700-1000 MHz Coupling for X3C09E2-20S(Feeding port1) -19.5 25ºC -55ºC 95ºC -19.6 25ºC -55ºC 95ºC -10 -19.7 -19.8 -20 Directivity (dB) -19.9 Coupling (dB) Directivity for X3C09E2-20S(Feeding port1) 0 -20 -20.1 -30 -40 -20.2 -20.3 -50 -20.4 -20.5 700 0 750 800 850 Frequency (Mhz) 900 950 Insertion Loss for X3C09E2-20S(Feeding port1) 0 25ºC -55ºC 95ºC -0.02 -0.04 -0.04 -0.06 -0.06 -0.08 -0.1 -0.12 -0.16 -0.18 -0.18 850 Frequency (Mhz) 900 950 1000 900 950 1000 Transmission Loss for X3C09E2-20S(Feeding port1) 25ºC -55ºC 95ºC -0.12 -0.16 800 850 Frequency (Mhz) -0.1 -0.14 750 800 -0.08 -0.14 -0.2 700 750 -0.02 Transmission Loss (dB) Insertion Loss (dB) -60 700 1000 -0.2 700 750 800 850 Frequency (Mhz) 900 950 1000 5 X3C09E2-20S Rev D Definition of Measured Specifications Parameter VSWR (Voltage Standing Wave Ratio) Return Loss Mean Coupling Insertion Loss Transmission Loss Directivity Frequency Sensitivity Definition The impedance match of the coupler to a 50Ω system. A VSWR of 1:1 is optimal. 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.
