Our standard A5 distribution amplifier, > 12 years old has >90dB adjacent out to out i...@10mhz, -130dB non adj iso @5MHz & out to in >-11...@10mhz. in to in (crosstalk is >9...@5mhz) Spur >-110, BB noise -148dBm/Hz, delay match <2ns (or 300ps within a group of 4 ops), phase/temp of 10ps/C, open/short any o/p gives phase change 0.5ps, however, most important specs are PN @1Hz -140dBc/Hz, 10Hz -150dBc/Hz, >100Hz -165dBc/Hz and AVAR <E-13/s, <3E-14/10s, <e...@100s. This old design draws much on the NIST BJT design (Fred Walls et al) and should be improved using later components. We need this performance with modern Active Noise Filters after Cs and in general Maser based lab work.
