Speedy DAC claims dynamic superiority for comms
The MAX5195 is a 14bit 260Msample/s DAC claimed to provide the world's best dynamic performance in spurious-free dynamic range, intermodulation distortion and signal to noise ratio.
Integrated on one monolithic IC, the MAX2027 delivers 23dB of gain range with +/-0.2dB accuracy over the full temperature range.
IP3 is +40dBm over the entire gain range, and noise figure is phenomenally low at 4.5dB.
Competing solutions have 10to 15dBm worse IP3 performance and suffer noise performance degradations as well.
The overall board space used by the DVGA is half that of a comparable discrete solution.
The MAX2027 has robust reliability and ESD performance that only a silicon-based process (SiGe) can deliver.
The MAX2027 outperforms today's very best GaAs solutions and X-amp-based products.
The MAX2027 is ideal for GSM DCS/PCS, cdma2000, WB-CDMA and CDMA multicarrier and single-carrier base-station applications, where high linearity and low noise are required for good bit error rate performance.
The MAX2027 is specified for operation from 50 to 400MHz, ideal for driving IF undersampled analogue-to-digital convertors (ADCs).
The MAX2027 is available in a small 20-pin TSSOP package.
Prices start at $4.95 (1000-up, FOB USA).
