A Balun is a special type of transformer that performs impedance transformation and balanced-to-unbalanced transformation. A standard RF device needs balanced connections to output a good signal. Suntsu’s balun transformer can transform an unbalanced connection into a balanced connection to not have noise present in the output. Suntsu’s balun transformer is 1.6mm x 0.8mm size with a frequency range is 2.4GHz~2.5GHz.
