This design illustrates the circuit modifications required to support high bandwidth and high frequency applications using current source DACs like the DAC38J84 with the TRF3704 modulator. The TRF3704 is a 6 GHz modulator capable of supporting wide BB bandwidths. The DAC38J84 is a 2.5 GSPS converter capable of supporting 600 MHz of baseband bandwidth. This combination facilitates operating at frequencies and bandwidths previously unattainable for high end communication systems.
A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
