Anritsu Launches 140 Gbaud Wideband Linear Amplifier
2 September 2026 
ANRITSU CORPORATION has announced it has launched the AH15203A/B, a 140 Gbaud wideband linear amplifier with integrated bias tee. Designed for engineers developing next-generation optical transmission devices, the new amplifier helps simplify high-speed device characterisation by delivering the broadband, high-output signal conditioning required for the Beyond-1 Tb era.
With a broad frequency response from 200 kHz to 125 GHz (-6 dB bandwidth), the AH15203A/B amplifies PAM4 signals up to 140 Gbaud with a maximum output of 2.0 Vpp. Its 15.0 dB gain and low jitter performance of 300 fs maximum help engineers maintain signal fidelity, compensate for transmission-path losses, and perform more reliable waveform evaluation during high-speed optical device development.
The AH15203A/B can amplify 140 Gbaud PAM4 signals from DSPs and other signal sources, while directly driving optical devices that require high-amplitude offset signals, such as modulators. This makes it well suited for characterising optical modulators used in next-generation 800GbE and 1.6TbE digital coherent transmission systems, as well as IM-DD optical modulators widely deployed in optical communications. For engineers, this provides a practical way to validate demanding device performance with greater confidence and efficiency.
By combining wide bandwidth, high output, low jitter, and an integrated bias tee in a compact drive amplifier, Anritsu says it helps customers reduce test complexity, improve confidence in measurement results, and accelerate the deployment of faster, more reliable data centre and network infrastructure.
Visitors to ECOC 2026, taking place from 21 to 23 September in Malaga, Spain, will be able to see the AH15203A/B demonstration and speak with Anritsu experts at stand 2075.
