There are hundreds of devices in that range that are complete oscillators.

All good ideas thus far.
This is a handy device to have for other purposes and would work well for

I should add that all of the LS04 outputs are summed through 270 Ohm
resistors, giving something close to 50 Ohms output. At any rate, I think

get something like 0 dBm into 50 Ohms, with the switchable attenuator
dropping it down to -20 dBm. Good level for rx antenna experiments.
