M/A-COM Technology Solutions MA8334 Series
of multi-throw high power switch modules are
SPDT and SP3T devices intended for use from
10 MHz to 1000 MHz. They are designed to
function with an input power of 100 watts, CW, into
a 50 Ω load with a nominal source VSWR of 1.3:1.
These switch modules are constructed using
advanced hybrid technology and utilize PIN diode
chips that have been optimized for low loss and
high reliability. These switch modules make use of
M/A-COM Tech’s, high voltage, CERMACHIP™
PIN diode chip distinguished by its low thermal
resistance and low intermodulation distortion.
Applications for the MA8334 switch modules
include 100W incident power T/R antenna and
diversity switches. Typical bias conditions for
nominal switch operation are +50mA @ +1V for
the low loss condition and -100V @ 0 mA for
isolation.
5 W @ + 25 °C .
derated to 0 W @ + 125 °C .
