A new design and fabrication method for an E-band frequency doubler module is introduced. The module utilizes a quartz probe in the form of a quasi-Yagi antenna to achieve efficient signal transition from the chip to the rectangular waveguide. To suppress the higher-order mode resonance generated in the packaged chip cavity, a pin-shaped electromagnetic bandgap structure is introduced to expand the operating bandwidth. To verify this method, the module is optimized through simulation, processed, and tested. The test results show that with an input power of 13 dBm, it is capable of outputting radio frequency signals with frequencies in the range of 60~80 GHz and power greater than 0 dBm. The test results match well with the on-chip test results of the chip, proving the feasibility of this method.
