NORWOOD, Mass., 16 June 2008.Analog Devices Inc. in Norwood, Mass., is introducing the ADF9010 integrated RF Tx modulator and Rx analog baseband for applications that operate in the 900 MHz frequency range, including RFID readers, industrial, scientific and medical (ISM) band radio communications devices, professional mobile radios, cellular base stations and RF-over-coax applications.
The ADF9010 integrates a Tx quadrature modulator with an integer-N synthesizer and on-chip low-phase-noise voltage-controlled oscillator (VCO).
The ADF9010 operates in the 840-MHz to 960-MHz frequency range. The receive path consists of a differential I/Q baseband programmable gain amplifier (PGA) and programmable low-pass filter (LPF). The Rx LPF gain is programmable from 3 dB to 24 dB in 3-dB steps. The Rx LPF features four programmable modes, with auto-calibrated cutoff frequencies of 330 kHz, 880 kHz and 2 MHz. The filter can be bypassed if necessary.
