TXA3-30/31 High Sensitivity Radio Detection Module Assembly

The A3-30 is a compact UAV radio detection and direction finding component that can scan, receive, and identify signals from common civilian UAVs. It demodulates signals meeting specific characteristics and transmits alarm data to a host computer. The module includes an independent direction-finding antenna input channel for connection to direction-finding antennas, enabling fixed-frequency staring functionality and target direction finding through manual or electrical antenna rotation.

The A3-30/31 features an 85×40mm PCB with double-sided SMT and a total thickness of 9mm. It includes four φ2.2mm through holes for chassis mounting using M2 screws. Note that components on the reverse side have a maximum height of 3mm, requiring at least 4mm high studs during installation to ensure adequate clearance between the PCB bottom and device base plate.
