RFW 122-M
Transmit receive control. High = Tx; Low = Rx
See RFW122-M datasheet for more details.
Note: RF Tx/Rx controls also the PA state. For low current standby mode this control
should be pulled Low.
RF RSSI indication
See RFW122-M datasheet for more details.
Max source and sinc current = 50 nA
RF Input / Output data.
See RFW122-M datasheet for more details.
RF Activate module control.
High = Active; Low = Non active
See RFW122-M datasheet for more details.
Ground signal
Feed Input voltage, 3 - 3.6 V; peak current 200 mA.
Recommended 3.4 V for optimal performance.
Note: Voltage should be regulated - recommended that ripple in peak current will not
exceed 50 mV peak/peak.

Ant SW
High ≥ VCC - 0.6 V
Low ≤ 0.6 V
Note: For low current standby mode this control should be pulled Low.
