The FM wireless microphone circuit uses a resonant coil

pattern etched onto the PCB to simplify the fabrication.

 

Technical data

- Power supply : 9VDC.

- Electric current consumption : 10mA. (max.)

- Signal transmitting frequency: 88 MHz

- IC board dimension : 1.64 in x 1.10 in

 

Circuit performances

The condenser microphone receives sound signals coming

into it. In the microphone there is an amplifier diaphragm that

transmits signals through C2 and to Leg B of TR1. TR1 then

generates radio wave frequency and mix the sound signals with

the generated radio frequency. Generation of radio frequency

depends on the trimmer, and the coil etched from the PCB at Leg

C of TR1 shall be connected to the antenna in order to broadcast

the sound
