Warren, NJ - ANADIGICS, Inc., a leading provider of semiconductor solutions in the broadband wireless and wireline communications markets, recently announced its new ACA2604 RF amplifier for fiber-to-the-home (FTTH) applications.
Based on ANADIGICS' popular ACA2601, the new amplifier features improved frequency flatness over temperature as required for domestic U.S. telco Gigabit Passive Optical Network (GPON) deployments. Like the company's ACA2601, the ACA2604 contains an integrated AGC circuit. Competing products require an additional external circuit to implement AGC; hence, using the ACA2604 will lower bill-of-material (BOM) costs by eliminating many discrete components. In addition, the new amplifier features a higher overall gain than the ACA2601, specifically 24 dB vs. 21 dB. This reduces the need for post amplification in the ONT/ONU or similar subscriber end equipment.
"ANADIGICS' specifically designed the ACA2604 amplifier to meet the ITU's stringent requirements for the higher electrical signaling demands of the emerging GPON market," said Ron Michels, Senior Vice President and General Manager, Broadband Business. "The amplifier's exceptional linearity and output power ensure optimal video performance for next generation digital TV content delivery systems. Many of our customers are already specifying the exact capabilities of the ACA2604 in their reference designs for optical assemblies."
In addition to the 24 dB gain, other key features of the ACA2604 amplifier include:
- 50 - 870 MHz operating frequency
- High linearity: 65 dBc CTB/CSO (79 channels)
- Low equivalent input noise: 4.5 pA/rtHz
- 400 ohm differential input impedance (No transformer required for photodiode interface)
- Single +5V supply
- 5 mm x 5 mm x 1 mm RoHS compliant surface mount package
- Pin-compatible with the ACA2601 RF amplifier
- Integrated AGC circuit with 22 dB gain adjust.
General availability of the ACA2604 amplifier is scheduled for first quarter 2008.
