This paper presents a multi-gigabit communication link over a polymer microwave fiber (PMF). A polymer fiber is a lightweight and low-loss channel at millimeter-wave (mm-Wave) frequencies. PMF is a promising, robust and low-cost technology to complement copper or optical links for high-speed applications with transmission distances up to several meters. The high carrier frequency of 120 GHz ensures low bending losses for small bending radii and features a large absolute bandwidth, which can be exploited to achieve high data rates with a simple modulation scheme. The used continuous-phase frequency shift keying (CPFSK) modulation results in a power efficient system at both the TX and the RX side. We report on 120 GHz 40 nm bulk CMOS TX and RX chips, the fiber and the coupling solution between the chips and the fiber. Data rates up to 12.7 Gbps over 1 meter, transmission lengths up to 7 meters at 2.5 Gbps and a link energy efficiency of 1.8 pJ/b/m for 4 meters and 7.4 Gbps are achieved for the complete communication link.

“…Also, CP-FSK does not require a variable gain amplifier, because the carrier amplitude holds no information. Finally, CP-FSK is resistant against LO pulling [7], which appears when an oscillator, a power amplifier and an antenna are integrated on the same chip.…”

A high-speed polymer microwave fiber (PMF) communication link is implemented in a 40nm bulk CMOS technology, by making use of two-tone CP-FSK modulation and a carrier frequency of 120GHz. The presented transceiver and enhanced coupler, with a loss of only 3.4dB, allows communication over a distance of 15m at 1.5Gbps. Data rates up to 17.7Gbps were achieved over a link distance of 1m with a BER < 10 −12 . The maximum product of data rate and distance is 60.8Gbps.m over a distance of 8m, resulting in an energy efficiency of only 1.2pJ/bit/m. The transmitter has an output power level of -1.9dBm at 120GHz and a DC power consumption of 11.1mW, the receiver consumes 59.6mW. The transmitter and receiver occupy an active area of respectively 0.025mm 2 and 0.43mm 2 in 40nm CMOS.
