I am new to the newsgroups, so please let me know if I am not following some 'written or unwritten' rules about posting. I posted this to sci.electronics.design and thought I would try this also. I am tasked with evaluating the feasablility of having an upconverter designed. The requirements are not clear yet, but the design will probably need to convert a 10-100 mhz sinewave to some L band frequency. The output will need to be gated on with an externally supplied signal that has programmable output amplitude, and will support most 'positive-logic' families. The gate signal will be 50ns to
1mS. The IF input will be CW and linear-sweep type waveforms. We are open to suggestions concerning off-the-shelf type solutions, as well as custom design. Also, we have been bitten in the past by 'out-of-house' designs that just don't seem to work as advertised. Any suggestions? Is there such a thing as a contract based upon a working prototype? Am I dreaming, or is there a way to guarantee a contractor or consultant delivers as promised?Reply
