RF2436

TRANSMIT/RECEIVE SWITCH

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.

Evaluation Board Schematic

Pin Function Description Interface Schematic

1RX OUT

Output pin for Receive mode. VSWR is 1.1:1 when Receive mode is

selected and highly capacitive when Transmit mode is selected.

2GND

Ground connection. For best performance, keep traces physically short

and connect immediately to the ground plane.

3TX IN

Input pin for Transmit mode. The input VSWR is 1.1:1 when Transmit mode

is selected and highly capacitive when Receive mode is selected.

4TX/RX

Transmit Mode/Receive Mode control pin. A “low” level chooses Receive

mode; a “high” level chooses Transmit mode. CMOS logic may be used to

drive the control input.

5ANT I/O

Input/Output pin from/to antenna and power supply pin. This pin must be

biased with VDD through a resistor.
