The PE42359 UltraCMOS® RF switch is designed to cover a broad range of applications from 10 MHz through 3 GHz. It has high ESD protection (2 kV HBM) which is essential for automotive applications, giving the product a longer life span as warranty repairs can be costly for manufacturers. The switch has low insertion loss of 0.35 dB @ 1GHz, 0.5 dB @ 2 GHz; and high isolation of 30 dB @ 1000 MHz, resulting in improved overall RF performance. Using a nominal +3V power supply voltage, a typical input 1 dB compression point of +33.5 dBm can be achieved. With low power consumption of only 9 microamperes, and a minimum power supply voltage of just 1.8V, the PE42359 enables longer battery life in portable applications such as RKE devices.
