Rockwell Scientific employs StratEdge's ceramic packages and assembly services
The ceramic microwave pack features four RF leads and multiple DC leads, in addition to cavities that were customized to fit the RSC chip and other components. The RF traces were optimized for speeds in excess of the current chip requirements. StratEdge designed and manufactured the package, as well as performed the polymer die attach, automated gold wedge wire bonding, lid sealing and marking services, and final lead trim.
RSC s 10 GHz bandwidth 1 GS/s dual track and hold (T/H) circuit is designed for direct sampling of multi-GHz signals. The RTH020 employs a GaAs circuit and is designed to turn a moderate bandwidth commercial ADC into a 10 GHz bandwidth analog-to-digital (ADC) converter. The bandwidth of 9 GHz for 0.5 Vpp inputs and over 10 GHz for small signals is more than three times that of any reported T/H, says the company. This allows sampling of 1 GHz signals with 10 bit precision, yet provides minimal noise or aperture jitter.
"Rockwell Scientific s dual track and hold chip dramatically increases ADC bandwidth and is a major step for ultra-wideband data acquisition," said Myung-Jun Choe, senior scientist and team leader at RSC s High Speed Mixed Signal ICs Department. "The StratEdge package handles the high speed and frequencies of our chip while providing a leaded package that can be easily assembled to our customers boards."
