FTTH RF amplifier enhanced for GPON

Warren, N.J.—Anadigics Inc.'s ACA2604 FTTH RF amplifier features improved frequency flatness over temperature as required for domestic U.S. telco GPON deployments.

Based on the company's ACA2601, the ACA2604 contains an integrated AGC circuit. According to Anadigics, the ACA2604 does not require an additional external circuit to implement AGC, which helps to lower BOM costs by eliminating many discrete components. In addition, the 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.

In addition to the 24 dB gain, other key features of the ACA2604 amplifier include a 50 – 870 MHz operating frequency; high linearity of 65 dBc CTB/CSO (79 channels); low equivalent input noise of 4.5 pA/rtHz; 400 ohm differential input impedance; a single +5V supply; and a 5 mm x 5 mm x 1 mm RoHS compliant surface mount package.

The ACA2604 is pin-compatible with the ACA2601 RF amplifier.
