摘要

研制了一种采用0.25 /spl μ m栅极GaAs mesfet用于2.5 Gb/s相干光纤传输系统的Gilbert-cell混频器IC。混频器IC工作于1-8.5 GHz RF 3db带宽，在-15 dBm至0 dBm的输入电平附近获得理想的平方律特性。该混频器集成电路在2.5 Gb/s相干光传输测试系统中实际运行，在10/sup -11/误码率下获得了-41.3 dBm的灵敏度。

2 - 8 GHz Gilbert-cell mixer IC for 2.5 Gb/s coherent optical transmission

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.<>
