1-to-8 Pulse and Frequency Distribution Amplifier

S/N005 phase-noise measurement at 10 MHz

Aug 18, 2017

Phase-noise measurements show a flat spur-free phase-noise and AM-noise floor of -162 dBc/Hz at >100 Hz offset from a 10 MHz carrier. Measurements at 5 MHz to follow. See wiki for results.

S/N005 assembled and tested

Aug 16, 2017

Amplifier S/N 005 was assembled and tested, housing PDA2017.07 and FDA2017.07 boards. Initial phase-noise tests show good performance, similar to the previous generation of the board. The new PDA2017.07 design using IDT5PB1108 has very fast rise-time (to be measured), possibly a quite low output-impedance (to be fixed?
