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.
