New Impedance Matching Scheme for 60 GHz Band Electro‐Absorption Modulator Modules

ABSTRACT This letter proposes a new impedance matching scheme of a traveling wave electro‐absorption modulator (TWEAM) module for a 60 GHz band radio‐over‐fiber (ROF) link. A microstrip bandpass filter (BPF) was used to achieve impedance matching at the 60 GHz band, and termination resistance was ca...

Summary:ABSTRACT This letter proposes a new impedance matching scheme of a traveling wave electro‐absorption modulator (TWEAM) module for a 60 GHz band radio‐over‐fiber (ROF) link. A microstrip bandpass filter (BPF) was used to achieve impedance matching at the 60 GHz band, and termination resistance was carefully designed to obtain an input impedance close to 50 Ω. Also, a bias circuit for the device was designed in the module. The measured return loss and frequency response show that the modulator module observes the characteristics of a filter without the need of a further tuning process.
