I'm using an Airwave 663 module. It's a 5.8GHz FM video + stereo audio transmitter module. Here is the datasheet: http://www.airwave.com.tw/specification/RF%20modules/AWM663TX.pdf
It is apparent that the module requires a 470uF 16V capacitor on the BYPASS pin. Compared to the other components on my board, this is absolutely massive. But I can't find any specification anywhere about what this capacitor does and whether or not this capacitor can be made smaller.
If anyone here has dealt with similar modules, what was your expereience?
