Abstract :
This paper focuses on the design of an RF-MEMS Dicke switched wideband LNA realized in a GaAs MMIC process that also includes a BCB cap type of wafer-level package. The 0-level packaged GaAs MEMS LNA circuit shows 10-17 dB of gain at 16-34 GHz when switched on. The off-state LNA gain is below -6 dB at 5-40 GHz resulting in 20-25 dB of isolation (on and off). To the authors´ knowledge, this is the first time a 0-level packaged MEMS switched wideband LNA MMIC with a high gain, isolation, linearity (OIP3≤24 dBm) and low noise figure is presented (NF=2.5-3.0 dB at 15-26 GHz).
