1.5V FM transmitter using a varicap diode and two transistors

Posted: 26 Apr 2015 10:15 AM PDT

This circuit is a 1.5V FM transistor circuit that use also two transistors like others circuit before. But this circuit is special that we use a varicap diode. Figure 1 is a schematic diagram - This circuit use the varicap diode number: SD111 or will use number 1S553, 1S85 instead. - The both transistors will […]
