Sirenza Introduces 40 Gbps Transimpedance Amplifier

Sirenza Microdevices, a start-up based in Sunnyvale, California, introduced a 40 Gbps common-base transimpedance amplifier (TIA) that employs electronically tunable transimpedance bandwidth control to compensate for various combinations of photo-detector and hybrid interconnect parasitics in order to simplify the manufacture of optical receiver modules. The device achieves 62.3 dB-ohm (1.3K-ohm) differential transimpedance with a bandwidth of 39.3 GHz, while consuming only 165 mW of DC power.
