CMM1434-SM
Features
34.5 dBm (Typ.) Saturated Output Power
31.0 dB (Typ.) Linear Gain
Fully Matched
Uncondtionally Stable
Low-Cost, Surface Mount Package
Optimum Thermal Dissipation
General Description
The CMM1434-SM is a four-stage pHEMT GaAs MMIC power amplifier
that is ideally suited for transmit subsystems designed for Ku-Band
VSAT applications.The CMM1434-SM provides 31.0 dB linear gain and
delivers 2.5 watts of output power at saturation operating from 13.5 to
14.5 GHz frequency.
Applications
The unconditional stability and internal matching provides for
reduction of external components making this product a simple and
low-cost solution.The low-cost 6mm x 6mm x 1.6mm surface mount
package offers the same excellent RF and thermal properties as a
typical flange package.
