GaAs MMIC Power Amplifier 22GHz~25GHz 34dBm

General Description

SAC3148 is a K-band GaAs MMIC power amplifier.  SAC3148 provides 22dB of gain, and 34dBm of output power for 1 dB compression and more than 24% PAE@OP-1dB, 24GHz from a +6V 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.
