1. Introduction
The Airvu 1.2GHz Low Pass Filter is placed on the end of the antenna port to
help eliminate or reduce radio interference problems on UAVs. It does this in
two ways
1. It reduces out of band noise entering the receiver that cause effects such
as reduction of control range
2. It reduces the antenna transmissions of out of band noise affecting other
circuitry on your UAV (such as disrupting the GPS receiver leading to loss
of fix, or a live video stream at 5.8GHz)
The LPF.12.01 internal ceramic filter has better insertion loss and stop band
performance than competing LTCC or lumped element filters, while also having
good rejection at band edges. It uses a standard SMA(M) Plug to SMA(F) Jack
interface. This filter is designed to be easily screwed onto this standard antenna
SMA connector. Custom versions can be made subject to NRE and MOQ.

Note
There can still be noise issues that a filter cannot solve. Such as noise that
can be radiated directly from the transmitter board and any wiring. Also no
filter can protect from in-band noise within the assigned operating
frequency of the receiver. Always try to place noisy components as far away
from a receiver and antenna as possible.
