The meter is a perfect addition to any power supply, battery chargers and dwtasheet electronic projects where voltage and current must be monitored. Once that is done turn off transmitter and disconnect its audio inputs.

Stereo FM transmitter circuit based on BH IC .

This BH pll fm transmitter includes features like: Buy it Now Add to Cart. There are 14 possible preset transmission frequencies, starting from Products with bhh problems declared to us within 45 days after delivery can be exchanged for a new device except cases of personal damage and any screen related problem.

What can be done to eliminate that noise? Any way such a capacitor is not at all a necessity here and the circuit will work perfectly even if the capacitor at pin 9 is omitted.

Headphone amplifier is small enough to fit in Altoids tin box, and thanks to low power consumption may be supplied from a single 9V battery. Stereo FM transmitter admin July 26, 7 Comments. L1 is a plastic former with 6mm adjustable ferrite slug similar to the figure shown http: Arduino Prototype uses all standard through-hole components for easy construction, two of which are hidden underneath IC socket.

PLL Stereo FM transmitter circuit How cool will it be if you can create a gadget that can transmit audio from your phone to your home stereo wirelessly?

BH chip may also be used a stand alone stereo encoder. It’s small, power efficient, yet customizable through onboard 2 x 7 perfboard that can be used for connecting various sensors and connectors.

Capacitors C18 and C19 are DC decoupling capacitors for the left and right channel inputs. There is a mistake in the circuit diagram of the above transmitter. At full output power, the circuit consumes only 20mA and has a channel separation of 40dB. Bhh will send a confirmation code to your mobile phone to verify that your contact details are correct.

BH HI FI Stereo Encoder / Multiplexer with Limiter and Low Pass Filter

Daasheet C1 and C17 are used to set the amount of pre-emphasis required and here with the used darasheet it is 50uS. Can I use my own pre-emphasis circuit? Price satasheet the app only: Now move the positive lead of the multimeter to the junction of R5 and R6 and adjust the slug ferrite core of L1 so that the multimeter reads 2V.

BH FM Transmitter chip includes a lot of bh in one small package. The L1 has to be readjusted for getting 2V between junction of R5, R6 and Ground every time you change the transmission frequency. More over it reduces the effects of changes in the capacitance of D1 on the pin 9. The link between pin 12 and pin 7 should be between pin 12 and pin 8.

If there any further costs bbh during the bh or repair process, we will ask you bh take responsibility for those as well. Lowering the volume of incoming audio source should do it. If you are building the above stereo encoder and have trouble finding some of the components like BH and 7.

The circuit shown here is of a good Stereo FM transmitter that can transmit high-quality signals up to a range of 70 feet. Previous post Next post. The meter bh a perfect addition to datwsheet bh supply, battery chargers bh other electronic projects where voltage and current must be monitored.

If power supply is being used make sure that all the diodes on the rectifier are bypassed with a 10n capacitors and that your voltage supply is gh filtered with bh least uF capacitor. You can control lights, fans, AC system, computer, printer, amplifier, robots, garage door, security systems, motor-driven curtains, motorized window blinds, door locks, sprinklers, motorized projection screens and anything else you can think of.

BH can be supplied with 6 – 15V voltage, consumes only around 25mA while providing very sound quality and improved 40dB channel separation.

Frequency selection bh very straight forward. This LC Meter allows to measure incredibly small inductances making it perfect tool bh making all bbh bh RF coils and inductors. This LC Meter allows to measure incredibly small inductances making it perfect tool bh making all types of RF coils bh bn Capacitor C10 works as a high frequency filter while R7 is meant for isolation.

How cool will it be if you can create a gadget that can transmit audio from your phone to your home stereo wirelessly?

It comes with pre-emphasis, limiter so that the music can be transmitted at the same audio level, low pass filter that blocks any audio signals above 15KHz to prevent any RF interference and crystal based stereo encoder for stereo transmission. Capacitor C8 connected between collector and base of Q1 provides additional datasheet frequency filtering.
