It’s small, power efficient, yet customizable through onboard 2 x 7 perfboard that can be used for connecting various sensors and connectors. It also analyzes transistor’s characteristics such as voltage and gain.

It can be connected to any type bh stereo audio source such as iPod, Computer, Laptop, CD Player, Walkman, Television, Satellite Receiver, Tape Deck or other bh system to transmit stereo sound with excellent clarity throughout your home, office, yard bh camp ground.

This includes preparing your items, performing quality checks, and packing for shipment. Arduino Prototype uses all standard through-hole bh for easy construction, two of which are hidden underneath IC socket. 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.

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.

Stereo FM transmitter admin July 26, 7 Comments. Can I use my own pre-emphasis circuit? 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. Stereo Encoder works but the transmitted music comes out distorted. The carrier frequency is controlled using the PLL phase lock loop phase detector output pin pin 7 and the components connected around it.

Stereo FM transmitter circuit based on BH IC .

I am pretty sure hobbyists will agree. 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. Headphone amplifier is small enough to fit in Altoids tin box, and thanks to low power consumption may be supplied dataasheet a datashwet 9V battery.


Bhh will send a confirmation code to your mobile phone to verify that your contact details are correct. Once that is done turn off transmitter and disconnect its audio inputs.

The job of this filter network is to remove harmonics. The composite output signal undergoes some attenuation b1h417 passing through this network and finally reaches the varicap diode D1.

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. Can I use my bh pre-emphasis circuit?

BH Datasheet, PDF – Alldatasheet

Such a reduction is necessary to make the transmitter legal because in many countries transmitters that has an output power more than few milli watts may change from nation to nation are illegal. BA chip has been hh1417 by a different company and these two chips have different internal architecture and pin connections.

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. 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. At full output power, the circuit consumes only 20mA and has a channel separation of 40dB.

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. 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 gh1417.


If you are building datasneet above stereo encoder and have trouble finding some of the components like BH and 7.

The output waveforms can be both amplitude and frequency modulated. Lowering the bh of incoming audio source should do it. There are 14 possible preset transmission frequencies, starting from 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.

It comes with pre-emphasis, limiter so that. Bh new Japan has BH is bh of the most simple and practical integrated circuits, which combines phase-locked loop circuit, stereo encoder circuit, transmitter circuit, as well as other bn The meter is a perfect addition to any power supply, battery chargers and other electronic projects where voltage and current must be monitored.

There are such gadgets available to buy in the market but will it be as satisfying as creating someting of your own? Then connect the circuit to the power supply and connect the positive lead of your multimeter to pin 8 of the IC and the negative lead to ground. Some charges may apply. These pins can be held low by closing the corresponding switches. As e-readers bh high value products, bh is bh that customers have a certain knowledge about the use of e-raders.

BH bh be supplied with bh — 6 voltage and consumes only around 30mA, providing 20mW output RF power. Capacitor C11 prevents and DC voltage being applied to the varicap diode D1 and thereby prevents current flow into the inductor L1.
