描述 Description

Please note: this product is being discontinued and is not recommended for new designs.

The ACA2604 amplifier for Fiber-to-the-Home (FTTH) applications is intended to be used in conjunction with the triplexer in fiber-coax line terminals. The device is driven by, and amplifies the output of, the video downstream path photodiode.

The high-impedance input of the ACA2604 eliminates the need for a costly transformer usually needed to interface to the photodiode, and a low equivalent input noise level offers excellent sensitivity. The device provides sufficient linearity to maintain low CTB and CSO levels in full-bandwidth (132 channel) systems, even across a wide gain adjustment range.

The ACA2604 is manufactured using proven MESFET technology that offers state-of-the-art reliability, temperature stability and ruggedness. The device operates from a single +5 V supply and is offered in a 5 mm x 5 mm x 1 mm surface mount package.
