摘要：

We demonstrate a 2-bit DAC (Digital to Analog Converter) employing microwave circuits for very high speed operation. Data switching and summation are performed using a diode sampler and broadband Wilkinson power combiner, respectively. The DAC was fabricated as a hybrid circuit, and it achieved 1 Gs/s. Due to the microwave circuit components it uses, our design is scalable for much higher frequency operation, as well as higher resolution.
