M/A-COM Technology Solutions Inc. (“MACOM”), a leading supplier of high performance RF, microwave, and millimeter wave products, announced a new SPDT Switch-Limiter that is ideally suited for S-Band military and commercial radar systems.

The MASL-011023 is an innovative switch-limiter solution for customers who require the industry’s fastest recovery time and highest power handling for S-Band receive protection applications.  Operating over the 2.7 - 3.5 GHz bandwidth, the device handles 125W of CW power at 85°C while providing ultra fast recovery time of less than 100 nanoseconds.  The switch is offered in a JEDEC standard footprint surface mount 7mm x 7mm QFN package that enables repeatable, high volume manufacturing.

The MASL-011023 delivers low insertion loss, high isolation and the lowest available flat leakage of 10 dBm in Rx mode and 7 dBm in Tx mode. This SP2T switch-limiter is designed to minimize insertion loss and handle +51 dBm CW power through the transmit path. This exceptional device also incorporates a fully integrated RF & DC bias network which provides the customer with a complete switch-limiter solution.

“The combination of highest power handling, lowest flat leakage and ultra fast recovery time make the MASL-011023 switch-limiter a unique and attractive solution for receiver protection in radar applications”, said Paul Beasly, Product Manager. “Furthermore, as a result of the high volume and automated package assembly, customers will benefit from consistent performance, tight manufacturing tolerances and superior reliability for critical radar requirements.”
