The RMWB04001 is a 2-stage GaAs MMIC amplifier designed as a 3.5 to 4 GHz Buffer Amplifier for use in the LO chain of millimeter wave point to point radios, point to multi-point communications, LMDS, and similar applications. In conjunction with other Raytheon amplifiers, multipliers and mixers it forms part of a complete 23 and 26 GHz transmit/receive chipset. The RMWB04001 utilizes Raytheon's 0.25m power PHEMT process and can be used in a variety of applications requiring a high gain medium power amplifier. 4 mil substrate
