“…Table 1 compares a typical IQ modulator with the EV12DS130A, a microwave DAC with >6GHz output bandwidth from e2v [1]. Here we can see that the performance of the two devices is comparable and also that the power consumption of the DAC is slightly less than the IQ modulator.…”

In advanced applications such as satellite telecommunications, digital radar, frequency hopping data links and micro-wave communications, powerful signal processors able to handle broadband signal vectors are becoming more common. The bottleneck is now the availability of high sampling rate and high linearity data converters, ADCs (Analog to Digital Converter) for reception and DACs (Digital to Analog Converter) for transmission.Advanced high bandwidth and high data rate data converters are revolutionizing the way that microwave communication systems are designed. The ability to perform direct microwave synthesis in the L, S and lower C bands brings higher flexibility and lower part count without any performance degradation. Some of these data converters are now available with space grade quality and as such are being used in many satellite applications. This paper describes an innovative 12bit 3GSps DAC, EV12DS130A, with an output bandwidth of 6GHz which gives good performance up to lower C band. It describes the design features of the device along with a novel output shaping scheme which extends the performance up to higher frequencies. The paper also covers the interfacing to the device which can often be problematic for space grade Application Specific Integrated Circuits (ASICs). A novel timing verification feature is described along with a timing mode which can reduce the input data rate but allows data output at higher clock speeds. A companion 10bit 1.5GSps ADC, EV10AS180A is also described, which offers good performance into the L band and along with the EV12DS130A can provide a complete space grade transceiver solution. Also covered are aspects of these components' performance under radiation testing.

The ability of the new generation of Digital to Analog Converter (DAC)s to convert from a digital signal directly into high frequency bands can be seen as a large leap in capability allowing greater system flexibility, reduction in component footprint and power consumption. This paper presents a new high speed, high bandwidth Digital to Analog Converter with high sample rate and high output bandwidth which enables the direct conversion of signals to frequencies up to band X. The component features a number of innovative design features which enable the optimization of performance in the different Nyquist zones. These include various output shaping schemes and interface methods. Results will be presented which show the performance of the circuit at output frequencies greater than 8GHz. The component's performance can result in highly flexible and waveform agile Radar signal generation systems.

“…Of course the CMOS section of available BiCMOS processes is generally very far from state of the art CMOS process (16nm), but a 130nm or a 90nm CMOS is more than enough for fast Data Converters design, together with a 160 GHz SiGeC HBT. This paper illustrates some major achievements in data conversion (ADCs and DACs) obtained thanks to 200GHz ft SiGeC (SiGe Carbon) fully Bipolar process [1], [2], [3], [4], and thanks to 120GHz fT SiGe BiCMOS 180nm process. In order to take advantage of both Bipolar and CMOS transistors, their performance with respect to transconductance, speed, matching, and noise are reviewed and compared in section VI.…”

This paper describes design techniques for Bipolar and BiCMOS analog circuits. Comparison on such performances as transconductance, speed, matching, noise of bipolar and CMOS transistors are reviewed and compared. Design achievements such as a single core 12 Bit 1.5GS/s Analog to Digital Converter (ADC) [1] and a single core 12 Bit 3GS/s Digital to Analog Converters (DAC) [2] based on a fully bipolar 200GHz SiGeC technology are introduced to illustrate the advantages and drawbacks of a fully bipolar technology for high speed data converters. A Quad 10 Bit 5GS/s ADC based on 4 interleaved ADC Core designed with a 120 GHz 0.18um BiCMOS technology is also presented, to illustrate the advantages brought by the combination of Bipolar and CMOS technologies.
