This is my first stab at an all-SMD transmitter. It operates from 1.5 to 5 volts. It draws 14 mA using a SAFT LSH 20 (13,000 mAh) 3.6 volt battery, so I should get about 928 hours (38 days) from the one battery. This one oscillates at 1.065 GHz using an MRF-901 microwave transistor. The antenna is 1/2λ and I got about 150 meters or so in an open field. Not bad for something smaller than a dime!
The tiny capacitors are hard to hold in place with a knife blade. Are there any better ways to hold these micro components in place for soldering?
