Low Noise Amplifiers (LNAs) are designed to amplify signals such that they rise above the noise floor in radio systems. An increase in signal level relative to noise makes it easier to process the signal. This is the primary use case of an LNA. However, it is not the only application. For instance, an LNA can be used in transmitter systems or in general, systems where signal amplification is required.  HOW SHOULD I CONNECT MY LNA?  The RFin or RF input terminal of the LNA should always be connected to the source of the signal. In receiver systems, RFin should...

FM radio is one of the most popular broadcast technologies out there. FM broadcast signals in most places in the world occupy the frequency range from 87.5 MHz to 108 MHz. These signals also happen to be very strong and overwhelm or saturate the receiver in a software-defined radio or RF receiver. This in turn impacts signal reception. You might for instance hear static instead of audio. If a user does not want to listen in to the FM broadcast band, then one way to mitigate the effect of this strong band of signals is to suppress or 'notch' them...

HackRF has a frequency range of up to 6 GHz and both transmit and receive capability along with excellent community support, there's a lot you can do with this product. But no matter how much you can do, there's always a desire to do even more! 🚀 And that's where an amplifier comes into the picture. An amplifier can increase both transmit and receive ranges of the HackRF.  This post answers a few different questions: The benefits of using an amplifier What amplifier can we use with HackRF? What are some of the limitations? So without further ado, let's get into...

Last updated on Feb 19, 2024 Our products ship from Canada. For shipments to the USA we use USPS in Canada we use Canada Post outside of USA or Canada we use PostNL or APC.

There's a five day handling time for all our shipments. We use a local carrier to ship across the US/Canada border for APC and USPS shipments. PostNL shipments are routed to a European distribution centre. ...

Last update on April 23, 2022 We've got some prototypes of our new Helium amplifier in-house and they are currently being tested. Over the past month we have been studying the performance of a Helium Miner with and without the amplifier. The miner is placed in the attic with the stock plastic antenna that has 3 dBi gain. Test Results We looked at the RSSI vs SNR values for one particular hotspot's beacons over time. Here are the results with and without the amplifier       The measured gain of the amplifier (in the lab) is about 13 dB...
