Broadband microwave generator, ~100 mW

P

Phil Hobbs

I need a microwave sweeper, maybe 100 MHz to 20 or 30 GHz, that has a
fair amount of output power--100 mW or thereabouts. I want to drive a
40 Gb/s lithium niobate optical modulator, and it would be nice to have
output levelling after the final amp.

Any favourites (used, preferably, and not too expensive)?

Thanks

With a high end that high (20 GHz+) the low end is going to be over 1 GHz
maybe over 10 GHz. If you really have to have 100 MHz you will need
multiple instruments. Mere generators that powerful in that frequency
range can be had, but VNAs(?), even synchronizable generators are not
common.

An hp8350 with a 83592 plugin does 10MHz to 20GHz. For less money you
can get a 83590 2-20GHZ plug in and a lower frequency 10MHz-2.4GHz
plugin 83522 (I think). The 100 mw is going to ned an amplifier
like a surplus avantek. Those cover smaller bands but they are
available.
