DATA SHEET • SKY66111-11: LOW-POWER BLUETOOTH LOW ENERGY FEM
If a fixed BIAS voltage (for example, from an LDO) is available in
the application circuit, using this instead of a resistor reduces the
variation of output power with VCC. To minimize SKY66111-11
current consumption in RX bypass and shutdown modes, the
voltage to the BIAS pin should be switched off when the CTX is
logic low.
