针对太赫兹谐波混频器，提出了一种基于半细分半全局设计方法（HS-HGDM）的单一功能单元设计模型。混频器的单个功能单元电路，如本振或中频低通滤波器（LPF）采用细分设计法（SDM）设计，其余电路采用全局设计法（GDM）设计。基于该模型的谐波混频器具有电路结构简单、变频损耗低、电路尺寸小、稳定性高等特点。本文提出了一种改进的用于次谐波混频器中频部分的紧凑型悬置微带谐振器滤波器。其余电路由一些基本的传输单元组成，例如用于主电路的高Z低Z阻抗传输线（H-Z L-Z TL）和用于提供RF/LO信号的全/减高WR4.3/WR 8。在射频200-240 GHz范围内，在中频1.8 GHz时，单边带（SSB）转换损耗为7.36±0.76 dB，本振功率2-5 mW，本振频率107 GHz时，双边带（DSB）噪声温度低于1034 K。这种宽带次谐波混频器工作在室温下，这使得它适用于亚毫米波或太赫兹无线通信系统和成像检测系统。
For the terahertz harmonic mixer, a design model based on Half-Subdivision and Half-Global Design Method (HS-HGDM) with a single functional unit is proposed. The single functional unit circuit of the mixer, such as LO or IF Low Pass Filter (LPF), is designed by Subdivision Design Method (SDM), and the rest circuits of the mixer are designed by Global Design Method (GDM). The harmonic mixer based on this model is characterized by simple circuit structure, low conversion loss, small circuit size and high stability. In this paper, an improved Compact Suspended Micro-strip Resonators (CSMRs) filter is developed for the IF part of sub-harmonic mixer. The remaining circuits consist of some basic transmission units, such as the High-Z Low-Z impedance Transmission Lines (H-Z L-Z TLs) applied for main circuit, and full/reduced height WR4.3/WR8 applied for providing RF/LO signal. In RF frequency range 200–240 GHz, a Single Sideband (SSB) conversion loss of 7.36±0.76 dB operating at IF frequency 1.8 GHz, and a Double Sideband (DSB) noise temperature below 1034 K with the LO power of 2–5 mW and the LO frequency of 107 GHz were achieved. This broadband sub-harmonic mixer operates at room temperature, which makes it applicable to sub-millimeter wave or terahertz wireless communication systems and imaging inspection systems.
