ADI launches new broadband modulators

BANGALORE, INDIA: ADI today launched its highest performance broadband direct conversion radio solution: the ADL5375 I-Q modulator and companion ADL5382 I-Q demodulator.

The ADL5375 and ADL5382 devices enable equipment designers to implement and standardize on solutions that address the range of operating frequency bands and standards, including GSM/EDGE, CDMA 2000, and W-CDMA, eliminating the need to select a modulator or demodulator for each cellular standard and operating band.

Further, designers can now implement one common radio platform for cellular standards as well as broadband wireless 802.16 WiMAX standards, which are increasingly being designed using direct conversion radio architectures, ADI said in a statement.

The ADL5375 offers 400 MHz to 6 GHz—a key attribute for direct up conversion transmitter architectures. It combines the industry’s highest linearity with 24-dBm output IP3, the highest linear output power with +10-dBm P1dB, and a low –161-dBm/Hz noise floor.

The ADL5382 covers the RF frequency range of 700 MHz to 2.7 GHz. It combines highest linearity specifications, exemplified by second and third order intercept point specifications of 60-dBm IP2 and 30-dBm IP3, and highest input compression of 13-dBm P1dB.

The ADL5375 modulator is available in full production and is priced at $4.98 per unit in 1,000-piece quantities. The ADL5382 demodulator is sampling now and will be available in full production quantities in March 2008. It is priced at $5.22 per unit in 1,000-piece quantities.
