43 Gbps Transimpedance Amplifier

The HMC7590 is a high-speed, high gain, low-power limiting transimpedance amplifier (TIA) used in optical receivers with data rates up to 43 Gbps. It features low input referred noise, 36 GHz bandwidth, 4 kΩ differential small signal transimpedance and output cross point adjustment. HMC7590 exhibits an optical input dynamic range between -10 dBm and +5 dBm while maintaining 10e-12 BER at 43 Gbps operation.

The HMC7590 is available in die form, includes an on-chip VCC bypass capacitor. It requires only supply decoupling capacitor as external component.

The HMC7590 requires a single 3.3V ±5 % supply and it typically dissipates less than 300 mW. The device is characterized for operation from –5 °C to +85 °C case (IC back side) temperature.
