hi ! my thesis is about designing a high frequency transimpedance amplifiers. Tia is used in optical communication links to convert the current from photo-diode to voltage . i searched a lot for specifications of a Tia that is used in Li-Fi but i got nothing. can anyone help me ? and i have another question how can i download full description for

You do not need ll the lenses that are needed for long range communication. Some of the receiver circuits are failry simple just low oise amplifiers connected to photo diodes. You could also try looking at TV remote control circuits for ideas. They are simple enough. What ever you do you will need to use quite a lot of power at the transmitter end
Dear all, Please help me. I need to ask that in optical fibre communication, which optical amplifier is the best from the three mentioned below. 1) Power amplifier 2) line amplifier 3) Booster amplifier. Waiting for your reply. Please help me.
what type of sensors are you interested in? today you can often buy sensors which have amplifiers built in together with an interface to connect directly to a microcontroller, e.g. the TC77 temperature sensor with an SPI interface TC77 for RF communication you could use
I search after communication unit The range between the 2 computers need to be approximate 10 meter I will glad to read suggestions for communities units and what is the preferable unit
Hello, I have modelled a system (in Mathlab/simulink environment) based on QAM- CCK (complementary code keying) modulation. As you know CCK provides 11MBs data rate for wireless communication systems using QPSK modulation. I had an idea and tried it in Mathlab/simulink environment. I thought that if I use QAM instead of QPSK I can either dou
Hi, I would like to make a project in communication for my education. ( an easy and unexpensive, eg: walkie talkie) Can any one help me? Please give me some topices and circuits. It's need to get data from net easily. Best regard. Zaw

who have the "RF power amplifiers for wireleness communication" by cripps
in the below sentence: You can download the book "RF Power amplifiers for Wireless communication" by Steve C. Cripps in the MFC fileman in the directory new ebook What is MFC fileman?
Hi Farshid-ar, You can find good theoretical and practical info at many places on the internet for Class C amplifiers, see links like: and and an interesting discussion on the formula that helps calculate the output impedance at giv
You want to use Infera-red communication, or RF wireless communication?
how equalization in communication related to the digital signal processing???
Laser diodes optical power is senstive for currrent in the diode usually they are linearily related over some range of current intensity, however Rf amplifiers o/p is usually voltage signal, although most laser diode applicaton are in digital communication where modulation is done by on-off of laser o/p but I wonder how can I modulate a laser diode
For mobile communication, TX frequency is always lower than RX frequency. Does anybody know this? and can give reasonable explaination. Thanks
"RF Power amplifiers for Wireless communication" Steve C. Cripps , Artech-House. I got his another book "Advanced technuques in PA". Thanks!
Here are some application notes from Motorola on RF power design. Transistor power amplifiers are usually broad band type because of the danger of damaging them if driven into a reactive load such as outisde the tuning range of a narrow band network. You can follow one of these amplif
This site has the classical Motorola RF power amplifier ap notes plus the parts needed to construct them. They also have complete kits including the PC board for some classical HF amplifiers.
