GENERAL DESCRIPTION
The NT2903 CHIP-CEIVERTM is a complete, single chip, FM transceiver solution, which will
operate in any 24 MHz band from 800-1000 MHz, including the Industrial Scientific Medical
(ISM) band (902-928 MHz). Utilizing a unique direct-conversion, zero-intermediate frequency
(zero-IF) receiver architecture, the NT2903 CHIP-CEIVERTM provides radio designers with a
"simple" RF path design solution. The device is fabricated as a monolithic, BiCMOS, integrated
circuit. The device's receiver section provides all of the required RF synthesis, filtering, gain
control, AFC, and demodulation functions. The transmitter section contains a directly modulated
VCO and RF power amplifier (PA). Internal, dual, high-performance phase locked loop (PLL)
synthesizers/VCOs allow full-duplex Tx/Rx operation over the entire RF tuning range. Tuning,
power management, and gain control functions are accomplished via a 3-wire serial interface.
