External DC blocking capacitors are required on all RF ports (47 pF capacitors are recommended). Use larger value capacitors for lower frequency operation (e.g. use 10,000 pF capacitors to optimize insertion and return loss at frequencies below 50 MHz). 6. Terminated return loss is governed by blocking capacitors internal to the device; see applications plot.
