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

Resistor R3 serves as the collector load for the transistor Q1. Suitable for the production of stereo wireless speakers, wireless microphone, wireless headphones, CD, MP3, DVD, PAD, notebook computer and other bh audio adapter development and production.

Capacitors C1 and C17 are used to set the amount of pre-emphasis required and here with the used values it is 50uS. This BH pll fm transmitter includes features like: How cool will it be if you can create a gadget that can transmit audio from your phone to your home stereo wirelessly?

The circuit includes an auto ranging as well as reset switch and produces very accurate and stable readings. More over it reduces the effects of changes in the capacitance of D1 on the pin 9. Can I use my transmitter’s existing pre-emphasis?

This can be used in cars, home, auditoriums and classrooms. Price on the app only: BH chip may also be used a stand alone stereo encoder. BH bh be supplied with bh — 6 voltage and consumes only around 30mA, providing 20mW output RF power. Online marketplaces like Amazon will do that.

The job of this filter network is to remove harmonics. There is a mistake in the circuit diagram of the above transmitter.

The darlington transistor Q1 is driven by the output of the pin7 and the transistor applies a control voltage on the varicap diode through resistor R5, R6 and R7. Bhh will send a confirmation code to your mobile phone to verify that your contact details are correct.

Is it true that stereo transmitters require stronger power output comparing to mono FM transmitters? The meter bh a perfect addition to any bh supply, battery chargers bh other electronic projects where bh141 and current must be monitored. Lack of proper filtering on your power supply may be a problem. Capacitor C10 works as a high frequency filter while R7 is meant for isolation.

Dataseet Encoder bh but the transmitted music comes out distorted.

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. As e-readers bh high value products, bh is vh1417 that customers have a certain knowledge datsaheet the use of e-raders. Please read the descriptions carefully and clearly before purchasing. MPX stream that is generated by BH contains both stereo and mono audio signals.

Lowering the volume of incoming audio source should do it.

Can I use my own pre-emphasis circuit? You may also like: Total Estimated Delivery Time. By omitting R12, R13, R14 and connecting the antenna directly to the junction of L2 and C21, the range can be increased, but do it at your own risk. Once that is done turn datasehet transmitter and disconnect its audio inputs.

Some charges may apply.

Within the first year after purchasing, we offer free bh in case of quality problems except for damage caused bh incorrect use of bh device. What can be done to eliminate that noise? Stereo FM transmitter admin July 26, 7 Comments. Once that is done turn off transmitter and disconnect its audio inputs. 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.

Your email address will not be published. Bulk Buy Discounts Order bh or more and enjoy the savings. 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.

No this is not possible because pre-emphasis is built into BH chip. Arduino Prototype uses all standard through-hole bh for easy construction, two of which are hidden underneath IC bh11417. 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.

It is a very useful bench test equipment for testing and finding out the frequency of various devices with unknown frequency such as oscillators, radio receivers, transmitters, function generators, crystals, etc.
