sp e - 15 - 8 - 0 3 9 /a / i c page 2 of 7 1. introduction the airvu bpf.58 5.8 g hz band pass filter is placed on the end of the antenna port to eliminate or reduce radio interference problem s on uavs. it does this in two ways 1. it reduces out of ba nd 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 contro l 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 antenna s at 5.8ghz ha ve a rp sma(m) connector as standard . this filter is designed to be easily screwed onto this standard antenna sma connector . contact your regional taoglas office for support note there can still be noise issues that a filter cannot solve. such as noise that can be radiated directly from the tra nsmitter 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.
