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
Figure 1: Application Block Diagram
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-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.
