Analog Devices Inc. ADRF5141 High-Power Transmit & Receive Switch ICs

Analog Devices Inc. ADRF5141 High-Power Transmit and Receive Switch ICs are 50Ω reflective SPDT switch ICs manufactured in the silicon process. These switch ICs are intended for transmitting and receiving applications with an integrated power limiter on the receive path. The ADRF5141 switch ICs operate within the 6GHz to 12GHz frequency range. These high-power switch ICs consume a low current of 13μA on the positive supply of 3.3V and 360μA on the negative supply of -3.3V. The ADRF5141 switch ICs use Complementary Metal-Oxide Semiconductor (CMOS)-/Low Voltage Transistor to Transistor Logic (LVTTL)-compatible controls. These switch ICs need no additional driver circuitry, making them a viable alternative to Gallium Nitride (GaN) and PIN diode-based switches.

The ADRF5141 switch ICs feature a fast switching time of 50ns and a fast response and recovery time of <10ns. These switch ICs come in a 20-lead, 3.0mm x 3.0mm, Land Grid Array (LGA) package. The ADRF5141 high-power switch ICs are RoHS compliant and operate within the -40°C to 105°C temperature range. Typical applications include electronic warfare, satellite communications, and radar.
