1.3 Operation

The MRF24J40MC module is based on the Microchip Technology MRF24J40 2.4 GHz IEEE 802.15.4 RF Transceiver IC. Serial communication and

configuration are documented in the “MRF24J40 Data Sheet” (DS39776).

This section emphasizes operational settings that are unique to the MRF24J40MC module design that must be followed for proper operation.

1.3.1 PA/LNA CONTROL

Operation of the PA U3 and LNA U2 is controlled by the MRF24J40 internal RF state machine through RF switches, U1 and U4, and the GPIO1 and GPIO2 pins on the MRF24J40. Figure 1-5 shows the PA/LNA block diagram. Figure 2-2 is the schematic diagram for the module.

FIGURE 1-5: PA/LNA BLOCK DIAGRAM

The internal RF state machine is configured for the PA/ LNA mode by setting TESTMODE (0x22<2:0>) = 111. Pins GPIO1 and GPIO2 control the RF switches, PA and LNA automatically when the MRF24J40 receives and transmits data.

Note: A complete explanation of the operation of

the PA/LNA control is documented in the

“MRF24J40 Data Sheet” (DS39776),

Section 4.2 “External PA/LNA Control”.

Voltage regulator U5 supplies a regulated 2.2V to the PA. This provides a stable voltage to the PA over the V

voltage range of the module. U5 is enabled or shutdown from GPIO3. Ensure that the GPIO3 direction has been set to output (TRISGP3 (0x34<3>) = 1). Setting a logic high (GPIO3 (0x33<3>) = 1) enables the voltage regulator and supplies voltage to the PA. Setting a logic low (GPIO3 (0x33<3>) = 0) will shutdown the voltage regulator, disabling the PA, and provides the lowest shutdown current.

MRF24J40MC

1.3.2 ENERGY DETECTION (ED)

Before performing an energy detection (see Section

3.6.1 “RSSI Firmware Request (RSSI Mode 1)” in the

“MRF24J40 Data Sheet” (DS39776)), perform the

following steps:

1. Configure the internal RF state machine to normal operation (TESTMODE (0x22F<2:0>)

2. Configure GPIO2 and GPIO1 direction for output (TRISGP2 (0x34<2>) = 1 and TRISGP1 (0x34<1>) = 1).

3. Set GPIO2 (0x33<2>) = 1 and GPIO1 (0x32<1>) = 0. This enables the LNA and disables the PA.

4. Perform the energy detection following the steps in Section 3.6.1 “RSSI Firmware Request (RSSI

Mode 1)” in the “MRF24J40 Data Sheet”

(DS39776).

Note: The LNA will amplify the received signal.

The RSSI value will include the receive signal strength plus the LNA amplification.

= 000).

1.3.3 SLEEP

To get the lowest power consumption from the MRF24J40MC module during Sleep, it is necessary to disable the PA, PA voltage regulator and LNA. To do this, perform the following steps:

1. Configure the internal RF state machine to normal

operation (TESTMODE (0x22F<2:0>) = 000).

2. Configure the GPIO3, GPIO2 and GPIO1

direction for output (TRISGP3 (0x34<3>) = 1, TRISGP2 (0x34<2>) = 1 and TRISGP1 (0x34<1>) = 1).

3. Set GPIO2 (0x33<2>) = 0 and GPIO1 (0x32<1>) = 0. This disables the LNA and the PA.

4. Set GPIO3 (0x33<3>) = 0. This shuts down the voltage regulator U5 that supplies 2.2 volts to the PA.

5. Put the MRF24J40 to Sleep following the steps

in the “MRF24J40 Data Sheet” (DS39776).

When waking the module, re-enable the PA/LNA mode.

Testing of the MRF24J40MC module was performed with the antenna types listed in Table 3-1

3.1.3 RF EXPOSURE

All transmitters regulated by FCC must comply with RF

exposure requirements. OET Bulletin 65 “Evaluating

Compliance with FCC Guidelines for Human Exposure to Radio Frequency Electromagnetic Fields” provides

assistance in determining whether proposed or existing transmitting facilities, operations or devices comply with limits for human exposure to RF fields adopted by the Federal Communications Commission (FCC). The bulletin offers guidelines and suggestions for evaluating compliance.

If appropriate, compliance with exposure guidelines for mobile and unlicensed devices can be accomplished by the use of warning labels and by providing users with information concerning minimum separation distances from transmitting structures and proper installation of antennas.

The following statement must be included as a CAUTION statement in manuals and OEM products to alert users of FCC RF Exposure compliance:

If the MRF24J40MC module is used in a portable application (antenna is less than 20 cm from persons during operation), the integrator is responsible for performing Specific Absorption Rate (SAR) testing in accordance with FCC rules 2.1091.
