| High Power SPDT Switch CXG1189AXR Description The CXG1189AXR is a high power SPDT (Single Pole Doble Throw) switch MMIC used in wireless communication systems, for example, GSM handsets, GSM/UMTS dual mode handsets. The Sony JPHEMT process is used for low insertion loss. (Applications: Antenna switch for cellular handsets, GSM, GSM/UMTS dual mode) Features Low insertion loss: 0.25dB@900MHz, 0.30dB@1.8GHz, 0.35dB@2.17GHz Low harmonics level: -35dBm (Max.) Package Small package size: 12-pin XQFN Structure GaAs JPHEMT MMIC This IC is ESD sensitive device. Special handling precautions are required. Sony reserves the right to change products and specifications without prior notice. This information does not convey any license by any implication or otherwise under any patents or other right. Application circuits shown, if any, are typical examples illustrating the operation of the devices. Sony cannot assume responsibility for any problems arising out of the use of these circuits. -1- E06144 CXG1189AXR Absolute Maximum Ratings (Ta = 25C) Control voltage Input power max.
