1. Introduction

The Airvu BPF.58 5.8GHz Band Pass Filter is placed on the end of the antenna

port to eliminate or reduce radio interference problems on UAVs. It does this in

two ways

1. It reduces out of band noise entering the receiver and causing 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 the control signal at 2.4GHz)

The ceramic filter inside the BPF.58 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 RP SMA(M) Plug to RP SMA(F)

Jack interface, as most antennas at 5.8GHz have a RP SMA(M) connector as

standard. This filter is designed to be easily screwed onto this standard antenna

SMA connector.

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.
