CXG1045N Datasheet | Sony Semiconductor Solutions

Description The CXG1045N is a DPDT (Dual Pole Dual Throw) antenna switch MMIC used in personal munication handsets such as GSM, GSM1800 or dualband. This IC is designed using the Sony's Ga As J-FET process. Features - Low insertion loss: 8 pin SSOP (Plastic) 0.4d B (Typ.) @900MHz 0.7d B (Typ.) @1.8GHz - High power switching P1d B: 38d Bm (Typ.) @900MHz 37d Bm (Typ.) @1.8GHz - Small package SSOP-8pin: (3 × 6.4 × 1.25mm) - Low current: 200µA (Typ.) Application - GSM900 or GSM1800 handsets - GSM900/GSM1800 dualband handsets Structure Ga As J-FET MMIC Operating Condition Control voltage: Vctl (H) - Vctl (L): 2.5 to 5V @Ta = 25°C ∗ Ga As MMICs are ESD sensitive devices.
