CMM1431-SM

Features

❏ 32.2 dBm (Typ.) Saturated Output Power
❏ 30.5 dB (Typ.) Linear Gain
❏ Fully Matched
❏ Unconditionally Stable
❏ Low-Cost, Surface Mount Package
❏ Optimum Thermal Dissipation

Applications
❏ Ku-Band VSAT Transmit Subsystems

Description

The CMM1431-SM is a four-stage pHEMT GaAs
MMIC power amplifier that is ideally suited for transmit sub­systems designed for Ku-Band VSAT applications. The
CMM1431-SM provides 30.5 dB linear gain and delivers 1.5
watts of output power at saturation operating from 13.50 to

14.50 GHz frequency.

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.
