PRODUCT DESCRIPTION The ANADIGICS ACA2604 amplifier is intended to be used in fiber-to-coax equipment, such as ONUs for FTTH systems incorporating RF overlay, or FTTB optical receivers for MDUs. 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 Supply Matching Circuit LNA 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 ANADIGICS’s proven MESFET technology that offers state-of-theart 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.
