Description:
The MSW2T-205X-194 series SP2T surface mount High Power PIN Diode switches are available in two
operating frequency bands: MSW2T-2050-194 operates from 50 MHz to 1 GHz and MSW2T-2051-194
operates from 400 MHz to 4 GHz. The MSW2T-205X-194 series of high power switches leverage high reliability
hybrid manufacturing processes which yield proven superior performance to both MMIC and 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 MSW205X-194 family of asymmetrical switches are 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 the Receive Port. The extremely low thermal resistance of the hybrid
assembly permits reliably handling up to 50 dBm CW power and up to 58 dBm peak RF incident power while
operating at the T

Notes:
1) 28 V ≤ V

≤ 125V
2) PIN diode min reverse DC voltage (V
HIGH
) to maintain high resistance state in the OFF PIN diode is determined by RF frequency. Incident
power, duty cycle, characteristic impedance and VSWR as well as by characteristics of the diode. The recommended min reverse bias
voltage (V
