GaAs MMIC Power Amplifier 4.5GHz~6GHz 37dBm

General Description

SAC3144 is a C band GaAs MMIC power amplifier.  SAC3144 provides 22 dB of gain, and 37dBm of output power for 1 dB compression and more than 30% PAE @OP-1dB, 5.5GHz from a +5V supply.

The chip has surface passivation for protection and backside via holes and gold metallization to allow a conductive epoxy die attach process, it’s ideal for Point to Point radio and multifunction radar applications
