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.
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
M/A-COM’s High Voltage CERMACHIP PIN diodes
for Lower Thermal Resistance and Lower
Intermodulation Products.

Notes:
1. For the MA8334-001 and the MA8334-004
Switches, the Small Signal Insertion Loss and
Isolation measurements are performed at
450MHz with the “ON” Port Forward Biased @
+ 50mA, +1V and the “OFF” Port Reverse
Biased at 0V, 0 mA.
For ( 100 W ) High Signal conditions, the
“ ON “ Port is Forward Biased @ + 50mA, +1V
and the “OFF” Port is Reverse Biased at
–100V, 0 mA.
2. Maximum Small Signal VSWR for all Switches
is 1.35:1 with Source and Load VSWR
< 1.05 :1 in 50 Ω System at specified 450 MHz
frequency.
3. Nominal Thermal Resistance for Each Diode
is 20 °C/W.
