Description

EasyEDA project for easy and quick build "SPDT Antenna switch" module for switching receiving antennas. Project includes schematic and PCB prepared for setting up into aluminum enclosure with dimensions 80 x 50 x 20 mm with SMA connectors. Version for mounting SMD components.

Current development progress:

Progress Progress Bug report

Input voltage: USB type B, DC 5 V;
Frequency range: 300 kHz - 2.5 GHz (according to the datasheet on AS169-73LF);
Insertion loss: 0.3 dB (300 kHz - 1 GHz), 0.4 dB (1 - 2.5 GHz);
Isolation: 25 dB (300 kHz - 1 GHz), 24 dB (1 - 2.5 GHz);
RF connector: SMA;
Feed line: 50 Ohm coaxial cable;
Used PCB Material: FR-4;
PCB thickness: 1.6 mm;
PCB copper weight: 1 oz;

Used only for switching receiving antennas! Using the unit in a transmitting radio channel may damage the AS169-73LF.
