MLink 900 can be broken down into four sub modules: ISM RF Deck (including integral antenna), GPS module (including integral antenna), Digital and Power Supply. These are shown in figure 5.1.1 of the block diagrams (Ref 1). The ISM RF Deck can be further broken down into the following key sub modules: TX Chain (PA), RX Chain (RX RF Front End Filter, LNA, RX RF Band Pass Filter, & Attn) and common modules (Transceiver (Analog Devices ADF7023), TR Switch, & Front End Filter). Please see Figure 5.2.1 of the block diagrams (Ref 1). Coordination of the operation of MLink 900 (radio link, power management, peripheral interface) is handled by the Firmware running on the microprocessor in the digital module. For the radio link in particular, in RX mode, the TR Switch is configured to the RX Chain where the LNA and Attn are adjusted to optimize the RF signal level into the Transceiver IC. The Transceiver IC down converts the RF signal to a 400 kHz IF and then FM demodulates it. In TX mode the Transceiver IC directly up converts the baseband signal to RF. After which the RF signal is amplified to the calibrated power by the PA, conducted through the TR switch (which is configured to the TX chain), and finally, low pass filtered before radiating from the integral antenna. Power (3VX) for the PA is provided by the regulator captured in figure 5.4.1 of the block diagrams (Ref 1). Similarly power (Vmain) for Transceiver IC incorporates several internal low drop out regulators. Furthermore to ensure that emissions are controlled, all interface lines (including power supply lines) are decoupled/filtered as they enter/exit the RF shielded area.

The maximum output power is limited by the saturated RF power of the PA (Ref 1 – Figure 5.2.1). Two parameters are used to control the RF output power over the dynamic range:  Fine Control - the RF output level from the Transceiver IC (Ref 1 – Figure 5.2.1) is programmable in 0.5 dB steps  Course Control - the bias voltage to the PA (Ref 1 – Figure 5.2.1) is controllable in 7 steps. In order to conserve energy in strong link margin environments the PA bias is reduced, reducing both the RF output power of the PA a…

MLink Circuit Description – Draft, Feb 10, 2014 4 Introduction This document shows how compliance with maximum RF exposure is met by the MLink module operating under FCC 15.247 and RSS 210 with integral and external Yagi antennas. 5 General Information Device category: Mobile with Integral antenna Fixed with external Yagi antenna Environment: Uncontrolled exposure in general public (uncontrolled environment) for Integral and external Yagi antenna 6 Antenna The MLink module is design for used with two antennas types – an Integral Antenna and an External Yagi Antenna. 6.1 Integral Antenna The integral antenna is a custom design specifically for use with MLink 900 module with a measured peak gain of 2.1 dBi (Ref 1). Configuration Antenna Polarization Type Freq. Band Max. Gain (dBi) Mobile or Fixed Vertical Omni 900 MHz 2.1 MPE Page 4 3/4/2014 8:07 PM Murandi Communications Ltd. 106, 4715 - 13th St. NE, Calgary, Alberta, Canada, T2E 6M3 Tel: (403) 777-9988 email [email protected] Fax: (403) 777-9989 www.murandi.com Confidential and Proprietary 6.2 External Yagi Antenna The external Yagi Antenna is made by several manufacturers (MaxStream Inc (A08-Y8NF) and Laird Technologies (PC904)) with a gain of 4.8 dBd (7 dBi) including a 1.2 dB min cable loss. Configuration Antenna Polarization Type Freq. Band Max. Gain (dBi) Fixed Vertical Yagi 900 MHz 7 7 Operating Configuration and Exposure Conditions The max conducted power for the MLink 900 module is 29 dBm with a 50% max duty cycle (max TX of 100 ms followed by 100 ms RX). The integral antenna is directly connected to the MLink 900 module, while the external Yagi antenna is connected through an RF cable. 8 MPE Calculation From FCC 1.1311 Table 1(B) and RSS-102 section 4.2 the MPE is 0.6 mW/cm 2 max @ 900 MHz. The MPE at 20 cm is separation is calculated as follows: MLink 900 module conducted TX power 29 dBm = 800 mW With 50% duty cycle 800 mW x 50% = 400 mW Spherical surface area with a 20 cm radius 4πr 2 = 5000 cm 2 For an isotropic antenna the RF intensity at 20 cm is 400 mW / 5000 cm 2 = 0.08 mW/cm 2 For the Integral Antenna with max 2.1 dBi gain (1.62 linear gain) the max RF intensity at 20 cm is 0.08 mW/cm 2 x 1.62 = 0.13 mW/cm 2 @ 20 cm separation which is less than the 0.6 mW/cm 2 max @ 20 cm specification Similarly for the External Yagi Antenna with max 7 dBi gain (5 linear gain) the max RF intensity at 20 cm is 0.08 mW/cm 2 x 6 = 0.4 mW/cm 2 @ 20 cm separation which is less than the 0.6 mW/cm 2 max @ 20 cm spe…

MLink 900 can be broken down into four sub modules: ISM RF Deck (including integral antenna), GPS module (including integral antenna), Digital and Power Supply. These are shown in figure 5.1.1 of the block diagrams (Ref 1). The ISM RF Deck can be further broken down into the following key sub modules: TX Chain (PA), RX Chain (RX RF Front End Filter, LNA, RX RF Band Pass Filter, & Attn) and common modules (Transceiver (Analog Devices ADF7023), TR Switch, & Front End Filter). Please see Figure 5.2.1 of the block diagrams (Ref 1). Coordination of the operation of MLink 900 (radio link, power management, peripheral interface) is handled by the Firmware running on the microprocessor in the digital module. For the radio link in particular, in RX mode, the TR Switch is configured to the RX Chain where the LNA and Attn are adjusted to optimize the RF signal level into the Transceiver IC. The Transceiver IC down converts the RF signal to a 400 kHz IF and then FM demodulates it. In TX mode the Transceiver IC directly up converts the baseband signal to RF. After which the RF signal is amplified to the calibrated power by the PA, conducted through the TR switch (which is configured to the TX chain), and finally, low pass filtered before radiating from the integral antenna. Power (3VX) for the PA is provided by the regulator captured in figure 5.4.1 of the block diagrams (Ref 1). Similarly power (Vmain) for Transceiver IC incorporates several internal low drop out regulators. Furthermore to ensure that emissions are controlled, all interface lines (including power supply lines) are decoupled/filtered as they enter/exit the RF shielded area.

The maximum output power is limited by the saturated RF power of the PA (Ref 1 – Figure 5.2.1). Two parameters are used to control the RF output power over the dynamic range:  Fine Control - the RF output level from the Transceiver IC (Ref 1 – Figure 5.2.1) is programmable in 0.5 dB steps  Course Control - the bias voltage to the PA (Ref 1 – Figure 5.2.1) is controllable in 7 steps. In order to conserve energy in strong link margin environments the PA bias is reduced, reducing both the RF output power of the PA a…

Configuration Antenna Polarization Type Freq. Band Max. Gain (dBi) Mobile or Fixed Vertical Omni 900 MHz 2.1 MPE Page 4 3/4/2014 8:07 PM Murandi Communications Ltd. 106, 4715 - 13th St. NE, Calgary, Alberta, Canada, T2E 6M3 Tel: (403) 777-9988 email [email protected] Fax: (403) 777-9989 www.murandi.com Confidential and Proprietary 6.2 External Yagi Antenna The external Yagi Antenna is made by several manufacturers (MaxStream Inc (A08-Y8NF) and Laird Technologies (PC904)) with a gain of 4.8 dBd (7 dBi) including a 1.2 dB min cable loss. Configuration Antenna Polarization Type Freq. Band Max. Gain (dBi) Fixed Vertical Yagi 900 MHz 7 7 Operating Configuration and Exposure Conditions The max conducted power for the MLink 900 module is 29 dBm with a 50% max duty cycle (max TX of 100 ms followed by 100 ms RX). The integral antenna is directly connected to the MLink 900 module, while the external Yagi antenna is connected through an RF cable. 8 MPE Calculation From FCC 1.1311 Table 1(B) and RSS-102 section 4.2 the MPE is 0.6 mW/cm 2 max @ 900 MHz. The MPE at 20 cm is separation is calculated as follows: MLink 900 module conducted TX power 29 dBm = 800 mW With 50% duty cycle 800 mW x 50% = 400 mW Spherical surface area with a 20 cm radius 4πr 2 = 5000 cm 2 For an isotropic antenna the RF intensity at 20 cm is 400 mW / 5000 cm 2 = 0.08 mW/cm 2 For the Integral Antenna with max 2.1 dBi gain (1.62 linear gain) the max RF intensity at 20 cm is 0.08 mW/cm 2 x 1.62 = 0.13 mW/cm 2 @ 20 cm separation which is less than the 0.6 mW/cm 2 max @ 20 cm specification Similarly for the External Yagi Antenna with max 7 dBi gain (5 linear gain) the max RF intensity at 20 cm is 0.08 mW/cm 2 x 6 = 0.4 mW/cm 2 @ 20 cm separation which is less than the 0.6 mW/cm 2 max @ 20 cm spe…
