Abstract :
A Gilbert-cell mixer IC for a 2.5 Gb/s coherent optical fiber transmission system using 0.25 /spl mu/m gate GaAs MESFETs has been developed. The mixer IC operates 1-8.5 GHz RF 3 dB bandwidth and an ideal square-law characteristic was obtained around input level of -15 dBm to 0 dBm. The mixer IC was actually operated in a 2.5 Gb/s coherent optical transmission test system, and sensitivity of -41.3 dBm for 10/sup -11/ bit-error-rate was obtained.<>
