Application Guidelines

The decoupling capacitors are optional and, if necessary, may be used for noise reduction. Decoupling capacitors on the con-

trol pins protect the control circuitry from possible RF leakage. For applications less than 300MHz the DC-blocking capacitors

on ports RF1, RF2, and ANT need to be 10nF instead of 100pF for best performance.
