August 27, 2013 - Operating over 2.7–3.5 GHz bandwidth, MASL-011023 handles 125 W of CW power at 85C 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.

Lowell, MA, 01851

Press release date: August 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 85C 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
Frequency GHz 2.7-3.5
Power Handling Tx Mode W 125, CW
Power Handling Rx Mode W 2.0, CW
Insertion Loss Rx Mode dB 0.85
Insertion Loss Tx Mode dB 0.25
Return Loss (Rx and Tx Mode) dB 14
Isolation Rx Mode dB 30
Isolation Tx Mode dB 17
Flat Leakage Rx Mode dBm 10
Flat Leakage Tx Mode dBm 7
Limiter Recovery Time to Final Insertion Loss ns <100

Production quantities and samples of MASL-011023 are available from stock. Final datasheets and additional product information can be obtained from the MACOM website at:
