Product Description
Systems
The RF2436 is a very low-cost transmit/receive GaAs MESFET switch. The
device can handle power levels as high as +28dBm and spans a fre-
quency range from DC to 2500MHz. 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. No negative voltage is required, and current con-
sumption is very low. VSWR for the active channel (transmit or receive) is
1.1:1. The device is housed in a very small industry-standard SOT 5-lead
plastic package.
