Single-MMIC Four-Channel Transmitter Module for Multichannel RF/Optical Subcarrier Multiplexed Communications Applications

We present a compact single monolithic microwave integrated circuit (MMIC) transmitter module for four-channel RF/optical subcarrier multiplexed (OSCM) communication applications. The developed module consists of one fully monolithic four-channel OSCM transmitter integrated circuit (IC) and four coupled-line filters. The MMIC is designed and implemented in a commercial 0.6m GaAs MESFET process ...

Fiber-Optic Links Supporting Baseband Data and Subcarrier-Multiplexed Control Channels and the Impact of MMIC Photonic/Microwave Interfaces

We report experimental and analytical results of a fiber-optic link that supports simultaneous transmission of baseband data and subcarrier multiplexed control-data channels. A novel transmitter design is used to optoelectronically combine baseband and subcarrier channels onto the optical carrier using a differential Mach–Zehnder (MZ) interferometer modulator. Microwave direct detection of the ...

Three-Dimensional MMIC and Its Evolution to WLCSP

An exciting program on monolithic microwave integrated circuit (MMIC) technology was pursued on from nearly 1983 to 1991, including its design and fabrication equipments, mainly in USA and Europe. In the era, “MMIC” was a very new concept which meant integration of microwave and millimeter-wave circuits on a die. By incorporating the CAD and measurement tools developed in the program, Japanese ...
