RF2436 0 RoHS Compliant & Pb-Free Product Typical Applications • Cordless Phones • Wireless Computer Peripherals • Wireless Security Systems Product Description 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 frequency 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 consumption 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. 1.60 + 0.01 0.400 1 TRANSMIT/RECEIVE SWITCH • General Purpose RF Switching • Commercial and Consumer Systems 0.15 0.05 2.90 + 0.10 0.950 2.80 + 0.20 3° MAX 0° MIN 0.45 + 0.10 0.127 1.44 1.04 Dimensions in mm.

VSWR is 1.1:1 when Receive mode is selected and highly capacitive when Transmit mode is selected. Ground connection. For best performance, keep traces physically short and connect immediately to the ground plane. 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. 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. Input/Output pin from/to antenna and power supply pin. This pin must be biased with VDD through a resistor. Interface Schematic Evaluation Board Schematic (Download Bill of Materials from www.rfmd.com.)
