81 GHz – 86 GHz Medium Power Amplifier

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