The Action principle of aroma 49 Wireless Handsfree . Base Set: 1. The power of each part was supplied from 3.6V 40mA Battery. 2. Transmit section: Voice Frequency send to Q5 to stronger the sound signal through connect line, and send to U1 to drive the power. Sound signal become FM radio frequency through D1’XL1, Q1, and it use Q2, Q3 transmitter to eradiate through Duplexer from the antenna. 3. Receive section: When the antenna receive the frequency from son device, it will be stronger by Q4 RF Low Noise Amp. Through Duplexer and change to sound signal by U2 FM radio circuit IC and then eradiate through connect line.
