Narrowband photoreceiver for analog radio-over-fiber in the 24.25-29.5 GHZ band [PDF]
45th European Conference on Optical Communication (ECOC 2019), 2019 The presented narrowband photoreceiver, optimized for a 27.5-29.5 GHz Analog-RoF link, is based on a 3-stage GaAs narrowband low noise amplifier which offers 24.4-dB gain, 2.1-dB noise figure and 26.6-dBm OIP3. An rms-EVM of 2.46/3.47% is achieved for 100/400-MBaud 16-QAM over the 24.25-29.5 GHz band.
