Operation at RF power levels >30 dBm requires increasing the positive
voltage level to put a larger reverse bias on the diodes while the negative
voltage level remains at -4V with a current of approximately 30mA. If you
are using -5V, use alternate assembly with off chip resistors.
Bond pads IA and IB bypass the on-chip series resistors to allow adjustment
of the current to the diodes in their forward biased state.
