I was attempting to ascertain whether anyone on the list had direct measurements, or other insight, into the close in residual phase noise performance of these parts, as I could not find any further specifications or internal circuit info in the associated datasheet and application notes. I have absolutely no aspirations of reaching a wideband noise floor of -178 dBc/Hz whilst using a device with 0 dBm output power and a noise figure of 8 dB. But I suspect I can do as well as, or better than, the op-amp designs, over a wider input bandwidth. Yes, if I need more than 0 dBm of output power, there will need to be another output buffer or gain stage in the design, hence the phrase "... as part of a reference distribution design ..." If you know of anything else with comparable reverse isolation, usable from at least 10-200 Mhz, in such a tiny package, that costs a buck a channel, please let me know!
