Anritsu launches 120 Gbaud PAM4 Wideband/High output linear amplifier

Anritsu Corporation (President Hirokazu Hamada) has started sales from July 24 of its 120 Gbaud Wideband Linear Amplifier AH15199A developed to evaluate 120 Gbaud PAM4 devices used by next-generation Ethernet 800GbE/1.6TbE interfaces.

This new amplifier features a wideband frequency response of 105 GHz at a –3 dB bandwidth and can amplify 120 Gbaud PAM4 signals to 2.0 Vpp.

The high gain of +16 dB and low jitter of 500 fs enable amplification of attenuated signals on transmission lines with high-quality waveforms.

Furthermore, when used as an 800GbE/1.6TbE digital coherent and IM-DD optical modulator driver, it can amplify 120 Gbaud PAM4 signals from various signal sources, such as DSP, and can directly drive modulators and other devices requiring high amplitude.

By selling this wideband linear amplifier, Anritsu is meeting its customers’ needs and contributing to the expansion and smooth operation of high-speed networks.

Development Background
Mobile data traffic is increasing with the growth of 5G and other services, but further increases in communication speeds for servers and network devices are a major concern.

The next-generation Ethernet standard for 800GbE/1.6TbE high-speed networking will use PAM4, which increases the transmission capacity per unit time to 120 Gbaud using 2-bit (4-value) signals. On the other hand, since higher communication speeds suffer higher signal attenuation, a linear driver is needed to faithfully amplify the PAM4 signal.

Product Outline
The AH15199A is a high-power linear amplifier supporting 2.0 Vpp signal evaluation with 120 Gbaud PAM4 to achieve high-speed, high-power (2 Vpp) data transmission at a 120 Gbaud rate with a low power consumption of less than 1.2 W.

The standard dedicated power supply, downsized to 1/19th, reduces the risk of damage from improper handling.
