P35-4230-C06-200
GaAs MMIC SPST TERMINATED
SWITCH, DC - 4GHz
Features
• Broadband performance
• Low insertion loss; 1.8dB typ at 2GHz
• Ultra low DC power consumption
• Fast switching speed; 3ns typical
• SO8 surface mount ceramic package
Description
The P35-4230-C06-200 is a high performance Gallium Arsenide single pole singe throw broadband RF
switch. It is suitable for use in broadband communications and instrumentation applications. A 50Ω
termination is presented at the isolated output of the switch. Control is effected by the application of
complimentary 0V and -5V levels to the control lines in accordance with the truth table below.
This die is fabricated using MCL's 0.5µm gate length MESFET process (S20) and is fully protected using
Silicon Nitride passivation for excellent performance and reliability. This device is packaged in a
ceramic package.
