laser diode driver

[adm]

Does anyone know of a laser diode driver for 1.5 Gb/s, which comes
packaged with a 50 ohm SMA connection? I have a laser diode that I am
trying to directly modulate for telecoms applications - the diode comes
with a 50 ohm matched SMA connector. Most of what I have been able to
find out there so far are the chip versions, which also comes with a lot
more bells and whistles than I need (I just mainly need a modulation and
bias current adjust).

Failing that, I am thinking of using a variable gain broadband amplifier
with bias tee.

Any suggestions, thoughts or comments?

Many thanks.

Don't diss those bells and whistles, at least not the protective
features. All it may take is a nanosecond of excess current and the
laser diode goes poof. If, for example, the supplies on your broadband
amp come up in a way that it generates a wee spike that might already be
enough.
