Colpitts Oscillator with Buffer Output Kit (#1720)
This is the Colpitts Crystal Oscillator PCB Kit. It consists of a one-transistor Crystal-controlled Colpitts oscillator and a one-transistor, emitter-follower output buffer/amplifier. You get all the parts you see, including the PCB, plus a schematic and several different crystals to experiment with.
It runs off of a 9-volt battery which is not included. This oscillator can deliver a 3-volt signal into 100 Ohms. It has been tested with crystals from 3MHz to 80MHz.
The PCB is approx 1.1" x 2.0", .062" thick, FR-4 with plated Thru-Holes. You not only get to build this great circuit, but it can also be used as a building block for home-made receivers and transmitters. This can also be used as a crystal tester by plugging in crystals instead of soldering them in.
Due to limited quantities, the Crystals listed below may vary in frequency as parts permit. You will get a total of 6 different crystals to test your circuit out.
Many NightFire kits come with a wide selection and quantity of passive components to encourage experimenting. The passive components in each kit have been optimized for that kit's specific IC. The Datasheets and Application Notes for the ICs and Transistors, along with hundreds of others, are located at DATASHEETS. We supply the parts, you supply the ingenuity. You get the following:
