This New Product Brief (NPB) is part of a video series highlighting the features, applications, and technical specs of newly-released products.

ANALOG DEVICES INC. Si Non-Reflective 44GHz SP4T Switches

Analog Devices ADRF5042 and ADRF5043 SP4T switches are manufactured on a silicon-on-insulator process and feature an ultrawideband frequency range up to 44GHz and a nonreflective 50Ω design.  

The switches offer 24dBm power handling for the through and terminated paths, supporting bidirectional operation with equal power handling capabilities. The ICs have logic and control pins to easily select the desired throw port or set all ports to isolation, with 30ns settling time to within 0.1dB of the final output. 

Isolated ports are terminated to 50Ω resistors, and provide isolation greater then 35 dB across the full frequency range, while the selected port offers 3.2dB or lower insertion loss. The ADRF5042 and ADRF5043 are pin compatible and housed in a 24-terminal 3mm x 3mm LGA package.
