Description and Applications
M/A-COM’s MA8334 Series of Multi-Throw High
Power Switch Modules are SPDT and SP3T Devices
designed for usage from 10 MHz to 1000 MHz. They
are rated to operate at 100 Watts CW RF power with
Nominal 1.3:1 Source and Load VSWR in 50 Ω.
5 W @ + 25 °C .
derated to 0 W @ + 125 °C .
These switch modules are constructed using
Ceramic-Hybrid technology and utilize PIN diode
chips optimized for lower loss and higher operating
reliability. These Switch Modules employ
1. Operation of this device above any one of these parameters
may cause permanent damage.
M/A-COM’s High Voltage CERMACHIP PIN diodes
for Lower Thermal Resistance and Lower
Intermodulation Products.
Case Style
Application of the MA8334 switch modules include
100 W Incident Power T/R and Diversity Switches.
Forward Bias Currents of + 50 mA @ +1V and
Reverse Bias Voltages of -100V @ 0 mA are typical
values for nominal Switch Operation.
