Linear FM 50Watt with BLY90 - A amplifier of force RF for the FM, is always
essential for the amateur that wants it strengthens some small transmitter, that
likely already it has manufactured or has been supplied ready. The present circuit
can give 50-60W RF force of expense, with control smaller than 15-20W in the
region of frequencies of FM, that is to say in the 88-108MHZ. Transistor that we
selected for ....(electronic design added 6/07) |

Low Pass Filter For FM 88-108 MHz - Filter used for eliminate unwanted
harmonic frequency at second and third. Notch filter, Band Pass Filter (BPF), and
High Pass Filter (HPF) sometime combined in constructing LPF design. Schematic
below for FM Broadcast Lowpass Filter 88-108 MHz….(added 08/08/08) |

MC145170 PLL FM Transmitter - In order to simplify the transmitter design,
we've used the new pll circuit from Motorola :the MC145170. This PLL includes the
prescaler and a serial standard bus called SPI. (circuit added 04/05/06) |

Minature FM Transmitter - This miniature transmitter is easy to construct and
it's transmissions can be picked up on any standard FM radio. It has a range
of up to 1/4-mile (Tony van Roon's 400 meters) or more, depending on the
line-of-sight, obstructions by large buildings,etc. It is great for room
monitoring, baby listening, nature research,....(Tony van Roon's electronic design
