Norwood, Mass.Analog Devices Inc. (ADI) has expanded its RF portfolio with what it claims is the industry's highest performance broadband direct conversion radio: the ADL5375 I-Q modulator and companion ADL5382 I-Q demodulator.
With broad operating frequency ranges, the ADL5375 and ADL5382 devices enable equipment designers to implement and standardize on products that address the wide 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.
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.
According to ADI, the ADL5375 offers the industry's highest dynamic range across the broadest frequency range--400 MHz to 6 GHz--a key attribute for direct up conversion transmitter architectures. The ADL5375 combines high linearity with 24-dBm output IP3, high 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. According to ADI, this represents the industry's highest dynamic range with the 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.
Pricing: In 1,000-piece quantities, the ADL5375 is $4.98 each and the ADL5382 is $5.22 each.
Availability: The ADL5375 is in full production; the ADL5382 is sampling now with full production quantities available in March 2008.
Datasheets: ADL5375 and ADL5382.
