What we aim to make a series fm radio transmitter? because we want to know the results of the schema obtained from books or the Internet or also because the task of teachers in the school, is fm radio transmitter circuit.
This is a FM transmitter circuit using semiconductor Maxim MAX2606 IC. In a series of nominal frequency is set to 100 MHz by the inductor L1, (390nH). Left and right channel audio signal from your source added by R3 and R4, and attenuated by R2 POT. R2 can be used as a volume control. POT R1 can be used to select the transmission line between 88Mhz and 108Mhz.Use wire 80 cm long as a series of transmitter circuit antena.FM In this fm radio transmitter is set to a nominal frequency of 100 MHz by the inductor L1, (390nH).

IC MAX2606 Description
The MAX2605-MAX2609 are compact, high performance, high frequency (IF) voltage-controlled oscillators (VCOs) fm radio transmitter circuit was designed specifically for wireless communication systems require a portable. They combine monolithic construction with low noise, low power operation in a small 6-pin SOT23 package.
This low voice VCOs feature an on-chip varactor and capacitor feedback can reduce the need for external tuning elements, making the MAX2605-MAX2609 ideal for portable systems. Only an external inductor is required to regulate the frequency of oscillation. In addition, fm radio transmitter circuit having an integrated differential output buffer is provided for driving a mixer or prescaler. Output buffer capable of supplying up-8dBm (differential) with a simple power fit. It also provides isolation from load impedance variations.
Fm radio transmitter circuit MAX2605-MAX2609 operate from a single 2.7 V to 5.5 V supply and offer low current consumption. IF oscillator can cover the frequency range of 45MHz to 650MHz.
