BIAS

External bypass decoupling for precision bias circuits.

Note: 1.920V ±20mV reference voltage (BIAS) is generated internally and cannot

drive an external load. Must be measured with 10GΩ meter such as Agilent 34410A,

normal 10MΩ DVM will read erroneously.

[1] For doubler mode of operation, pin 28 (RF_N) and pin 29 (RF_P) outputs must be shorted together.
