Specifications

(1)

The maximum transmit power range is 18dBm to 0.125dBm in 0.125dBm decrements.

(2)

FCC, IC/ISED, ETSI/CE, SRRC (MODAx only), and MIC are supported.

(3)

Rates are grouped into high modulation rates (MCS7, 54 OFDM and 48 OFDM) and lower modulation rates (all other rates).

(4)

The back-off range is 0 dBm to 18 dBm in 0.125 dBm increments, with the maximum back-off not exceed that of the maximum transmit

power.

(5)

The range of losses if from 0 dBm to 7.75 dBm in 0.125 dBm increments.

(6)

The antenna gain has a range of -2 dBi to 5.75 dBi in 0.125 dBi increments.

TX Power Control for 5 GHz

5 GHz power control is done via Image Creator where the maximum transmit power is provided (1). Within

Image Creator, power control is possible per channel, region (2), and modulation rates (3). In addition, it is

possible to enter an additional back-off (4) factor per channel and modulation rate for further margin to

regulatory requirements.

Finally, it is also possible to set the TX and RX trace losses to the antenna per band (5). The peak antenna

gain (6) can also be provided, thus allowing further control. For a full description of options and capabilities

see Uniflash with Image Creator User Guide.

Brownout and Blackout Conditions

The module enters a brownout condition whenever the input voltage dips below VBROWNOUT (see Figure 5-

4 and Figure 5-5). This condition must be considered during design of the power supply routing, especially

if operating from a battery. High-current operations, such as a TX packet or any external activity (not

necessarily related directly to networking) can cause a drop in the supply voltage, potentially triggering a

brownout. The resistance includes the internal resistance of the battery, contact resistance of the battery

holder (four contacts for a 2× AA battery), and the wiring and PCB routing resistance.

NOTE

When the module is in HIBERNATE state, brownout is not detected. Only blackout is in

effect during HIBERNATE state.
