Responding to an increasing demand for wider bandwidth data pipes for fiber-to-the-home (FTTH) and RF-over-Glass (RFoG) systems, ANADIGICS, Inc. announced an upgrade to its ACA2604 RF amplifier supporting operation to 1 GHz. The improved ACA2604 enables cable MSOs and telco service providers to increase data rates as well as the number of channels available to consumers. This functionality is essential as sales continue to grow for high-definition TVs, VOD, and other OTT services which require significant amounts of bandwidth.

The ANADIGICS ACA2604 RF amplifier is designed for use in fiber-to-coax equipment, such as optical network units for FTTH and RFoG systems incorporating radio frequency overlay, and fiber-to-the-building (FTTB) optical receivers for multiple dwelling units. The ANADIGICS amplifier, driven by the forward path photodiode in a fiber optic RF receiver, forms the optical to electrical interface and boosts overall output to the in-home coax wiring.

The ACA2604 is manufactured using ANADIGICS’ proven GaAs technology that features state-of-the-art distortion performance, temperature stability, and ruggedness. The amplifier operates from a single +5 volt supply and is offered in a 5 mm x 5 mm x 1 mm surface mount package.

Additional facts and highlights about the ACA2604 include:

* Has an operating frequency between 50 and 1,000 MHz

* Features high linearity: CSO/CTB = - 65 dBc (@ 79 Chan., 21dBmV/ch )

* Offers low equivalent input noise: 4.5 pA/rtHz

* Does not require a transformer for interface to photodiode

* Features 22 dB Gain Adjust

* Packaged to be RoHS compliant

* Pin compatible with ANADIGICS’ ACA2601 RF amplifier

* Reference circuits and BOMs are available for common applications.

ANADIGICS will showcase this and other technology at the SCTE Cable-Tec Expo 2010 in New Orleans, Oct. 20-22.
