MITSUBISHI SEMICONDUCTOR <GaAs FET>
MGFC36V3436
3.4 - 3.6GHz BAND 4W INTERNALLY MATCHED GaAs FET
DESCRIPTION
The MGFC36V3436 is an internally impedance-matched
GaAs power FET especially designed for use in 3.4 - 3.6
GHz band amplifiers. The hermetically sealed metal-ceramic
package guarantees high reliability.
