MMIC SPDT Reflective
Switch, DC - 3GHz
The P35-4211-000-200 is a high performance Gallium
Arsenide monolithic single pole double throw RF switch,
suitable for use in broadband communications and
instrumentation applications. An open circuit reflective
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 Bookham Technology's 0.5 m
gate length MESFET process (S20) and is fully protected
using Silicon Nitride passivation for excellent performance
and reliability. This device is also available in a plastic
surface mount package (see P35-4211-1).
