– Time base of the RF frequency
For IF and RF frequency, 40MHz crystal is a clock reference.
– Synthesizer
Synthesizer inside Transceiver. Internal voltage controlled oscillator (VCO) provides the desired LO signal base on the phase-locked loop (PLL) with a relatively wide tuning range for this application. Internal fractional nPLL allows support for a wide range of reference clock frequencies
– Wi-Fi Transmission
Baseband data is modulated and up converted to the 2.4GHz ISM and 5-GHz U-NII bands, respectively. Linear on chip power amplifier are included, which are capable of delivering high output powers while Meeting IEEE802.11ax and IEEE802.a/b/g/n specifications without the need for external PAs.
– Wi-Fi Receiver
The SDA8702PAH has a wide dynamic range, direct conversion receiver that employs high-order on-chip channel filtering to ensure reliable operation in the noisy 2.4GHz ISM band or the entire 5GHz U-NII band. Control signals are available that can support the use of optional LNAs for each band,which can increase the receive sensitivity by several decibels. Reverse direction isolation of LNA inside Transceiver IC suppresses unwanted radiation.
-Bluetooth Low Energy
The ACAU711R support the Bluetooth5.2 LE and 5.2 BLE 2Mbps

Approval Statement
● FCC approval statement
RF Software restrictions
- Contention-Based Protocol, as demonstrated in the FCC test report, is permanently embedded in the module and is not host-dependent and can’t be changed by anyone.
- Operation of transmitters in the 5.25-5.35GHz, 5.47-5.725GHz bands in this Modular device will only associate and connect with a low-power indoor access point or subordinate device and never directly connect to other client devices.
This feature is included in its firmware and can’t be changed by anyone. - Operation of transmitters in the 5.25-5.35GHz, 5.47-5.725GH bands in this Modular device will always initiate transmission under t he control of a low-power indoor AP or subordinate except for brief trans missions before joining a network. These short messages will only occur if the client has detected an indoor AP or subordinate operating on a channel. These brief messages will have a time-out mechanism such that if it does not receive a response from an AP it will not continually repeat the request.
This device complies with Part 15 of the FCC’s Rules. Operation is subject to the following two Conditions:
- This device may not cause harmful interference.
- This device must accept any interference received, including interference that may cause undesirable operation.
To satisfy FCC exterior labeling requirements, the following text must be placed on the exterior of the end-product.
Contains Transmitter module FCC ID: A3LACAU711R
This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications.
However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference b y one or more of the following measures:
-Reorient or relocate the receiving antenna.
-Increase the separation between the equipment and receiver.
-Connect the equipment into an outlet on a circuit different from that to
which the receiver is connected.
-Consult the dealer or an experienced radio/TV technician for help.
-The OEM integrator is responsible for ensuring the end-user has no manual instruction to remove or install module.
-The module is limited to installation in mobile or fixed applications.
FCC Caution: Any changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate this equipment.
This device meets all the other requirements specified in Part 15E, Section 15.407 of the FCC Rules.
– RF exposure considerations
The module has been certified for integration into products only by OEM integrators under the following condition:
-The antenna(s) must be installed such that a minimum separation distance of at least 20cm is maintained between the radiator(antenna) and all persons at all times.
-The transmitter module must not be co-located or operating in conjunction with any other antenna or transmitter except in accordance with FCC multi-transmitter product procedures.
This device can support Ad-hoc and Wi-Fi Direct for 2.4GHz, UNII 1, and UNII 3 bands.
The device operates strictly as a client in DFS channels (with passive sca n). It does not support ad-hoc, Wi-Fi Direct Group Owner, Hotspot, or any other peer-to-peer modes that may initiate a network in DFS channels (U NII2-2A and UNII2-2C band)
<Regulatory notice to host manufacturer according to KDB 996369 D03 OEM Manual v01>
List of applicable FCC rules
This module has been granted modular approval as below listed FCC rule parts.
-FCC Rule parts 15C (15.247, 15.407)
Summarize the specific operational use conditions
-The OEM integrator should use equivalent antennas which is the same type and equal or less gain then an antenna which installed an original module.
RF exposure considerations
The module has been certified for integration into products only by OEM integrators under the following condition:
– The antenna(s) must be installed such that a minimum separation distance of at least 20 cm is maintained between the radiator (antenna) and all persons at all times.
