Analog Devices (ADI) has announced the release of a new integrated RF demodulator, the ADRF6801.
The part integrates ADI's fractional-N PLL (phase locked loop) synthesizer and low-phase-noise VCO (voltage controlled oscillator) with a high dynamic range demodulator. It also includes such features as an RF balun, three LDOs (low-dropout regulators), and the necessary baseband buffer amplifiers.
Operating over a frequency range from 750 MHz to 1150 MHz, the ADRF6801 demodulator features a noise figure of 14.3 dB, input IP3 (third order intercept) of 25 dBm , and a P1dB (input compression point) of 12.5 dBm. The ADRF6801 supports the SPI/I2C serial interface for PLL programming and the device provides the option of selecting between an external LO (local oscillator) source or an internally generated LO signal.
ADI claims the ADRF6801 demodulator enables radio developers to shrink circuit board area, reduce the bill of materials, reduce risk and shorten product development time, thereby lowering total system cost.
The ADRF6801 is suitable for RFID (radio frequency identification) systems, cellular base stations, point-to-point radios, satellite communications, VHF/UHF radios, defense systems, ISM-band applications operating in the 900 MHz frequency range, industrial equipment and other applications.
The ADRF6801 demodulator is priced at $9.98 per unit in 1,000-unit quantities.
