The RF2425 is a very low-cost single-throw, double-pole GaAs MESFET switch. There are two bidirectional input/ output channels which can be turned off or on by a single logic control line. Two of the ports may be tied together externally to make a transmit/receive switch. The device can handle power levels as high as +32dBm and spans a frequency range from DC to 2000MHz. The switch will operate from power supply voltages as low as 1.5V and as high as 6V with a CMOS logic driver for the control input.
