A new 2,4 GSps, 16-bit digital-to-analog converter (DAC) from Analog Devices provides exceptional dynamic range performance in the 100 to 300 MHz band for complex IF transmitters. The AD9154 also includes an on-chip phase-locked loop and eight-lane JESD204B interface.
The combination of features allows designers to use a single device to meet all of their requirements in multicarrier GSM and LTE transmitters designed for wireless macro base stations, point-to-point microwave radio, military radios and radio test equipment. The converter includes a range of features optimised for complex IF (intermediate frequency) transmit applications, including complex digital modulation, input-signal power detection, and gain, phase and offset compensation.
Functionally, the chip up-converts a pair of I/Q digital input signals, creating a complex IF signal at the input to a pair of on-chip DAC cores. It features several interpolation modes, increasing the sampling rate of the digital signal to the Nyquist frequency to enable simpler, less costly transmitter filters following the DAC analog output. It also implements digital signal correction for quadrature modulator up-converters to cancel RF local oscillator feed-through and unwanted sidebands.
