I'm trying to figure out what this diode is.
The marking indicates "A7" and also has "t36" stamped on it suggesting maybe a 1N4007 rectifier diode.
However, when I test it with my multimeter I get a forward voltage of 0.05v and reverse voltage of 1.7 V. Forward resistance of 107 Ω and reverse resistance of OL. Nothing out there seems to match these low values. I was thinking that it's a Schottky diode, but I'm at a loss. The circuit is for a small low power radio transmitter. Below is the schematic and a picture of the diode itself.
