RFIC Supports IF-To-Baseband Conversions

Said to be ideally suited for driving dual-channel, low-cost CMOS A/D converters, such as used in various wireless networking applications, the AD8348 broadband quadrature demodulator enables intermediate frequency-to-baseband conversions of 50 MHz to 1 Gz. Besides its demodulator, which includes a dual mixer core and local oscillator phase splitter, the new radio frequency integrated circuit (RFIC) melds on-chip a 45-dB linear-in-dB variable gain amplifier and singled ended-to-differential amplifiers for driving baseband ADCs. The device is also said to offer high linearity, exceptional amplitude/phase balance, and 60-MHz demodulation bandwidth, enabling it to support most high-order modulation formats, including QAM, QPSK and 8-PSK. The AD8348 can be used over a -40°C to +85°C temperature range, is housed in a 28-lead TSSOP, and costs $4.95 each/10,000. For more details, call ANALOG DEVICES INC., Wilmington, MA. (800) 262-5643.
