• Commercial and Consumer Systems
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 +32 dBm and spans a
frequency range from DC to 2000MHz. The switch will
operate from power supply voltages as low as 1.5 V and
as high as 6V with a CMOS logic driver for the control
input.
• Single Power Supply of 1.5V to 6.0V
• Low Current Consumption
• 0.5dB Insertion Loss at 900MHz
• 24dB Crosstalk Isolation at 900MHz
• +31dBm Output P1dB
