High-Power SPDT Switch-Limiter has recovery time of <100 nsec.

Press Release Summary:

High-Power SPDT Switch-Limiter has recovery time of <100 nsec.

Aug 27, 2013 - Operating over 2.7–3.5 GHz bandwidth, MASL-011023 handles 125 W of CW power at 85°C and delivers flat leakage of 10 dBm in Rx mode (7 dBm in Tx mode). JEDEC standard footprint, SMT, 7 x 7 mm, QFN package enables repeatable, high-volume manufacturing, and fully integrated RF and DC bias network provides complete switch-limiter solution. Suited for S-Band applications, SPDT/SP2T switch-limiter is designed to minimize insertion loss and handle +51 dBm CW power through transmit path.

MACOM Announces Highest Power Handling and Fastest Recovery Time SPDT Switch-Limiter

Press release date: Aug 22, 2013

Reliable surface mount device is ideal for high power S-Band switch applications and enables repeatable high volume manufacturing

Lowell, MA — M/A-COM Technology Solutions Inc. (“MACOM”), a leading supplier of high performance RF, microwave, and millimeter wave products, today 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.”

The table below outlines typical performance:
Parameter Units MASL-011023
