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.
