| CXG1045N High Power DPDT Switch for GSM Description The CXG1045N is a DPDT (Dual Pole Dual Throw) antenna switch MMIC used in personal communication handsets such as GSM, GSM1800 or dualband. This IC is designed using the Sony's GaAs J-FET process. Features * Low insertion loss: 8 pin SSOP (Plastic) 0.4dB (Typ.) @900MHz 0.7dB (Typ.) @1.8GHz * High power switching P1dB: 38dBm (Typ.) @900MHz 37dBm (Typ.) @1.8GHz * Small package SSOP-8pin: (3 x 6.4 x 1.25mm) * Low current: 200A (Typ.) Application * GSM900 or GSM1800 handsets * GSM900/GSM1800 dualband handsets Structure GaAs J-FET MMIC Operating Condition Control voltage: Vctl (H) - Vctl (L): 2.5 to 5V @Ta = 25C GaAs MMICs are ESD sensitive devices. 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.
