SLWS223B August 2011 – November 2015 TRF3705
The TRF3705 is powered by supplying a nominal 3.3 V to pins 18 and 24. These supplies can be tied together and sourced from a single clean supply. Proper RF bypassing should be placed close to each power supply pin.
Ground pin connections should have at least one ground via close to each ground pin to minimize ground inductance. The PowerPAD™ must be tied to ground, preferably with the recommended ground via pattern to provide a good thermal conduction path to the alternate side of the board and to provide a good RF ground for the device.
