Anadigics, Inc., Warren, N.J., has expanded its wireless infrastructure portfolio with the introduction of the ADR3410, 1 W, InGaP HBT amplifier. The amplifier addresses medium-power, base-station applications and provides adjacent-channel power rejection (ACPR) of greater than 70 dBc, while meeting the reliability requirements of the wireless infrastructure market.

Anadigics' RF designers optimized the ADR3410 for ACPR performance rather than the more common and less stringent two-tone OIP3 figure of merit. This product characterization provides the industry with an amplifier that meets the real-world requirements of the base-station environment, in which spectral regrowth and signal splatter can create serious problems. The amplifier can be tuned, with external matching elements, for optimal performance over any wireless band from 850 to 2200 MHz, including WCDMA, PCS, and GSM, delivering 12.5 dB of gain, and +29.5 dBm of one dB power compression (P1dB) at 2160 MHz.

The amplifier delivers a failure in time (FIT) rate of less than 400 per billion hours of operation. The amplifier uses an industry-standard pinout configuration in an wight-pin, SOIC S27 package. The die is mounted to a heat slug, offering excellent thermal dissipation and contributing to the device's high reliability. The device is biased through an external inductor directly from a single +5 V power supply and uses an internal active bias circuit with a current adjust input for current control.

The ADR3410 is priced at $5.05 in quantities of 1000 units.
