Product Description

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.
