M/A-COM Technology Solutions Inc of Lowell, MA, USA (which makes analog semiconductors, components and subassemblies for RF, microwave and millimeter-wave applications) has launched a single-pole, double-throw (SPDT) switch-limiter suitable for S-band military and commercial radar systems.
The MASL-011023 is a switch-limiter for users that require fast recovery time and high power handling for S-band receive protection applications. Operating over the 2.7-3.5GHz bandwidth, the devicve handles 125W of CW power at 85°C while providing recovery time of less than 100ns. 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 (0.85dB Rx mode; 0.25dB Tx mode), high isolation (30dB Rx mode; 17dB Tx mode) and what is claimed to be the lowest available flat leakage of 10dBm in Rx mode and 7dBm in Tx mode. The SP2T switch-limiter is designed to minimize insertion loss and handle +51dBm CW power through the transmit path. The device also incorporates a fully integrated RF & DC bias network, providing 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," claims product manager Paul Beasly. "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," he adds.
Production quantities and samples of the MASL-011023 are available from stock.
