The EXP8603 is a GaAs MMIC power amplifier designed for 50-Ohm systems, and specified for operation in the 81 to 86 GHz range of E-Band.

The EXP8603 enables delivery of 25.5 dBm RF output power when driven to 3 dB of gain compression, and maintains good linearity well below the onset of gain compression.  Typical small-signal gain is 18 dB with flatness of ±0.6 dB over a 1.25 GHz window. DC power consumption is as low as 1.9 W.

The EXP8603 also provides a built-in E-Band power detector, and internally de-couples DC from RF input and output ports to simplify system level design.
