RF Transmitter Module SR3225SAA
RF transmitter module SR3225SAA is a wireless transmitter module for the UHF range. This module houses a crystal resonator, capacitors for an oscillation circuit, a PLL, and a Power Amp in a 3.2 mm x 2.5 mm ceramic package. The crystal resonator is optimally matched with the IC at the factory. The SR3225SAA is ideal for small wireless transmitters because wireless transmission can be achieved simply by combining it with an external controller.
