I found these surface mount rf amplifier’s on Mouser. They have no minimum stated frequency floor but are documented to work up to several (2.8) ghz. They are available for about USD$0.52 in individual quantities. The package is listed as MCPH6. The pins are closer than a SOP23. I was able to get it on an Adafruit SOP23 breakout, but it was very careful work.
I measurement the voltage gain at from 20mhz and down. The gain drops as the frequency drops. I found that SMA3107 is not really linear until about 3.2mhz. Somewhere below that it looks like some oscillation is occurring.
