| IP개요 | we presents two key building blocks of a fully integrated frequency extender module for vector network analyzer (VNAX) applications in sub-terahertz (sub-THz) frequency ranges. A harmonic recycling sixtupler and a wideband distributed amplifier are co-designed to enable a compact and scalable on-chip solution. The proposed sixtupler efficiently generates 6f₀ harmonic with a simulated peak output power of –8.3 dBm and a wide 3-dB bandwidth of 111–165 GHz, achieving high spurious harmonic suppression across the D-band. The distributed amplifier delivers a flat simulated gain of 10 dB across 1–136 GHz, ensuring sufficient LO drive power to the down-conversion mixers. Fabricated in a 28 nm CMOS process, the proposed components demonstrate the feasibility of CMOS-based VNAX frequency extension, overcoming the limitations of conventional discrete and BiCMOS based modules. This architecture establishes a foundation for future development of multi-band, fully integrated VNAX systems with enhanced measurement flexibility and reduced system complexity. |
