Amplifying WiFi Signal with an Op Amp: Is It Possible?

AI Thread Summary
Attaching an op amp to a WiFi transmitter for signal amplification is not effective due to op amps' inability to handle high frequencies cleanly. Instead, RF amplifiers are recommended for amplifying 2.4GHz signals, with caution advised to avoid violating FCC regulations. Directional WiFi antennas are also suggested as an alternative for improving signal focus in specific areas. Searching for WiFi boost circuits can provide additional solutions. Overall, using the right components is crucial for effective WiFi signal enhancement.

could one attach an op amp to a wifi transmitter to amplify the signal? thanks.

I think its a bit more complicated then so. I am not familiair with the wifi standards, bur op-amps can't realle keep up, or keep the signal clean, if the frequenzy gets to high. but there are ic's that can. Try searching for wifi boost circuits or something on google.

Not an opamp, but you can amplify the 2.4GHz signal with an RF amplifier:

But, you also would need to be careful not to make it too large, since that would violate FCC rules in the US and other governmental regulations in other countries.

You can also buy directional WiFi antennas, if you want to aim your transmissions in a more directional way (like down a hall of a dormitory or something).
 

Thread 'Underwater piezoelectric sensor array receive sensitivity'

Hi all I have some confusion about piezoelectrical sensors combination. If i have three acoustic piezoelectrical sensors (with same receive sensitivity in dB ref V/1uPa) placed at specific distance, these sensors receive acoustic signal from a sound source placed at far field distance (Plane Wave) and from broadside. I receive output of these sensors through individual preamplifiers, add them through hardware like summer circuit adder or in software after digitization and in this way got an...

Thread 'Following up on the recent thread about Earth Resistance measurements'

I have recently moved into a new (rather ancient) house and had a few trips of my Residual Current breaker. I dug out my old Socket tester which tell me the three pins are correct. But then the Red warning light tells me my socket(s) fail the loop test. I never had this before but my last house had an overhead supply with no Earth from the company. The tester said "get this checked" and the man said the (high but not ridiculous) earth resistance was acceptable. I stuck a new copper earth...

Thread 'Beauty of old electrical and measuring things, etc.'

Even as a kid, I saw beauty in old devices. That made me want to understand how they worked. I had lots of old things that I keep and now reviving. Old things need to work to see the beauty. Here's what I've done so far. Two views of the gadgets shelves and my small work space: Here's a close up look at the meters, gauges and other measuring things: This is what I think of as surface-mount electrical components and wiring. The components are very old and shows how...
