K-band capable DAC removes need for signal up-conversion and costly mixers

e2v have launched the EV12DS460, a 6GSps digital-to-analog converter (DAC) which can achieve clean signal generation up to 26.5GHz. The new device is claimed to be the world’s first DAC to perform signal generation directly in the K-band frequency (18GHz-27GHz), removing the need for signal up-conversion and the costly mixers that perform this task. Radio Frequency applications operating at higher bands will benefit from system simplification through size, weight and power savings, meeting growing demands to reduce the cost of system ownership. With an ability to operate in the previously up-converted K-band frequency, the device contains the largest choice of DAC settings to optimise performance up to 26.5GHz. It is also equipped with four output operating modes and includes an option for program pulse shaping, making it proficient at handling the most specific of RF applications. Laurent Monge, vice president of semiconductors at e2v, commented, “Removing up-conversion stages in our customers’ systems operating up to K-band will help them to significantly simplify system design. We’ve always pushed the limits of signal conversion technology since developing the world’s first microwave frequency capable data converter, and the EV12DS460 is evidence of this.” Each packaging option for the device guarantees dynamic performance across different temperature ranges, including military grade at -55C to 125C, offering a powerful and versatile data conversion solution.
