T/R Switch Handles 50-W CW Power

Nancy Friedrich | ED Online ID #14885 | February 2007

By relying on a proprietary multi-octave technology, a family of high-power transmit/receive (T/R) switches promises to be compatible with the latest gallium-nitride (GaN) and LDMOS solid-state amplifiers. The switches cover the 20-to-2500MHz band. The model M20-064 T/R switch, for example, is capable of handling up to 100 W with a low insertion loss of 1.0 dB maximum. Its output voltage-standing-wave ratio (VSWR) is less than 1.42:1. The switch operates from –40° to +85°C. The switches are built on ceramic substrate in a thermally efficient aluminum package. For noise immunity, a built-in driver circuit interface is TTL or RS-422.

Hi Mr. Khanifar,

I hope you do remember from Powerwave. I am now back to Israel and believe we have a solution to your T/R switch requirement. Please send me a mail and/or leave your contact information and we will take it from there.

Kind Regards,

Gentlemen, I need a quotation for quantity of 1000-5000 p/a. Also in our application the average power handling is form 10-20W. Is it possible to reduce the insertion loss. The BW is is around 2.5-2.7GHz.

Thanks.
