MRQ
Input
Master Request
17
RF_SHDN
RF Shutdown
This pin indicates the status of the RF Transceiver
for GR0136 module:

Low = Shutdown

High = Active
18
ON_OFF
Input
This is used to turn ON/OFF the Internal Power
supplies of the GR0136 module.

Low: Node consumes <1uA

High: Node is active and will run through a
wide range of power states.
19
WAKE
Input
Wake up pin
20
VBATT
Power
Input power to GR0136 module. This power
domain is low current but is used 100% of
the time to supply Supervisory domains.
21
RF_TXENA
Output
This signal is used to indicate status of the Power
Amplifier for the GR0136 module:

Low = OFF

High = Enabled (Transmitting)
The rise edge can be used to trigger a Host CPU’s
ADC read of VBATT (battery voltage while under
maximum load).

23
RF_PORT1
50 Ohm
RF port for GR0136 module. This is 50 Ohm
port, DC coupled. RF1 is required but both
are desired for antenna diversity. Single port
or dual antenna port can be configured in the
provisioning process.

25
RF_PORT2
50 Ohm
RF port for GR0136 module. This is 50 Ohm
port, DC coupled. Single port or dual antenna
port can be configured in the provisioning
