A conjugate regenerative divider will have asinewave output.
It only requires a mixer an amplifier or two and a couple of bandpass
filters.
It will have lower phase noise than all(?) alternative techniques.

A good question for the group...

Hi:
I have both a GPS Frequency standard (Trimble Thunder Bolt) which
outputs the 10
MHz reference and also the 1 PPS signal. In addition, I have a
Collins AEU unit
which has a 10 MHz Rubidium reference inside. Both units work well
and produce a
very accurate reference signal for the units that require a 10 MHz
reference.
The challenge is that I am looking for a source of a 10:1 frequency
divider so I
can create a 1 MHz reference for my Rockwell Collins HF-80 system.
Can you
suggest a source of a high quality frequency divider that outputs a
(nearly)
sine wave signal? We only need two units - one for production and one
for our
development lab.
The object is to provide a very accurate source of 1 MHz and 10 MHz
to the
various radio systems used in our disaster and humanitarian relief radio
network. When you send data, you need to be exactly on frequency.
Any help would be great. Just need to be pointed in the right
direction. While
we could try to design something to meet this objective, I am sure
that someone
has already done this.
Thank you.
Kevin
