Description:
The MSW2T-2041-193 SP2T surface mount High Power PIN Diode switch operates from 400 MHz to 4 GHz.
The MSW2T-2041-193 high power switch leverages high reliability hybrid manufacturing processes which yield
both superior RF and thermal characteristics performance compared to MMIC or Glass Carrier based
technologies. The hybrid design approach permits precise PIN Diode selection to optimize RF performance
while maintaining competitive cost targets. The small form factor (8mm x 5mm x 2.5mm) offers world class
power handling, low insertion loss, and superior intermodulation performance exceeding all competitive
technologies. The MSW2041-193 symmetrical switch is 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. The extremely low thermal resistance of the hybrid
assembly permits reliably handling up to +52 dBm CW power and up to +57 dBm peak RF incident power while
operating at the T
