Teledyne e2v HiRel has announced the availability of a new high-power SPDT switch available in a multi-chip module (MCM). The TDSW002040X-198 operates from 100 MHz to 2 GHz and can handle up to 400 W of CW power and 1 KW of peak power. This SMT PIN-diode hybrid exhibits superior RF and thermal performance compared to MMIC or glass carrier-based technologies.
The TDSW002040X-198 is a symmetrical switch, tailored to minimize Transmit-to-Antenna loss while maximizing Transmit-to-Receive isolation and to enable maximum flexibility as the designer can assign either port as Transmit Port and the other as the Receive Port. It has a small form factor (10.1 mm x 6.2 mm x 2.5 mm) and offers world-class power handling, a low insertion loss, and superior intermodulation performance exceeding all competitive technologies. The extremely low thermal resistance of the hybrid assembly permits reliably handling up to +56 dBm (400 W) CW power and up to +60 dBm (1 kW) peak RF incident power while operating at an ambient of 125 °C.
“Our military customers requested this part because their previous supplier exited the market, leaving them without a solution,” said Mont Taylor, VP of Business Development at Teledyne HiRel. “The TDSW002040 is surprisingly small given the very high power-handling it is capable of, making it perfect for modern military communications transmit/receive switching.”
The device is shipped from Teledyne e2v HiRel’s Product Distribution Center, in Milpitas, California, and is available to US customers only.
