OCTOBER 20, 2010 -- Aiming for RF-over-glass (RFoG) and other fiber to the home (FTTH) systems, Anadigics, Inc. (NASDAQ: ANAD) has announced an upgrade to its ACA2604 RF amplifier supporting operation to 1 GHz. The improved ACA2604 is designed to enable cable MSOs and telco service providers to increase data rates as well as the number of channels available to consumers.
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.
"Delivering 1-GHz performance from the ACA2604 is a significant milestone in our efforts to ensure that broadband service providers have the components necessary to provide the highest performance networks," said Joe Cozzarelli, senior dDirector, Broadband RF Product Line at Anadigics.
The ACA2604 is manufactured using Anadigics' GaAs technology, which the company asserts features state-of-the-art distortion performance, temperature stability, and ruggedness. The amplifier operates from a single +5 V supply and is offered in a 5x5x1-mm surface-mount package.
Additional product highlights Anadigics cited include:
- Has an operating frequency between 50 and 1,000 MHz.
- Features high linearity: CSO/CTB = - 65 dBc (@ 79 Chan., 21 dBmV/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
