Conclusion
This study proposes and implements an E-band transceiver MMIC in a waveguide package. The waveguide module comprises a transceiver chip fabricated using a 0.1-µm standard GaAs pHEMT process and a microstrip-to-waveguide transition. Multiple filters and a high isolation mixer are appropriately designed to obtain better spur rejection. The IF frequency is carefully selected to avoid stronger in-band harmonics. Measurement results show that the waveguide module achieves a 50-dB power dynamic range at an appropriate SNR margin over a frequency range of 66–76 GHz. The total power consumption is 420 mW for one module. This implies that the specially designed E-band transceiver waveguide module can be effectively used in mmWave radio channel emulation applications.
