A Fully Packaged 140 GHz Analog Radio-over-Fiber Transmitter Chipset with SiGe driver and TFLN modulator PIC

An experimental demonstration of an integrated 140 GHz analog radio-over-fiber transmitter chipset is presented. The chipset consists of a single-ended push-pull Mach-Zehnder modulator on a TFLN PIC with a flip-chipped 130 nm SiGe PA. The chipset achieves an electro-optic 3 dB bandwidth of 20 GHz at a center frequency of 130 GHz and is shown to support data rates of 2 Gbps.
