This design will be mass produced soon (pre orders welcome), with a case and will support the features below; 

1, Bias tee power, both as sink, and as a source. Sinks 4.5V(minimally) at 70mA(max) to power the LNA itself, with option to pass the power upstream for active antennas (such as patches). It can also accept USBC power at 5V with C-C cables to supply power up and downstream of the device.

2, Front end is protected by a SAW filter, to prevent front end overloads especially in urban environments with 5G/LTE deployments nearby or other strong out of band signals such as aircraft/broadcasting.

3, will feature a conductive case that will minimize the effects of local RFI on this device. 

4, This design uses a DCDC converter on the input, will accept any voltage from 4.5V to 24V, without becoming very hot, allowing for a wide supply voltage.

And lastly, I intend to price this \~28USD, to stay competitive with the current offerings of the SAWBird, which I intend to exceed in terms of specs and ease of use. Other filters for different frequencies are also available, just state what you wish to have and I have the ability to get it done, such as for Inmarsat L band services



Ships from Singapore to all over the world. Made with love and not a cheap Chinese product. 

Design is **CC BY-NC-SA 4.0** and available on request.
