1.4 List of Product Models

1.5 Main Structure

• NJR4652 is an IC-type module that packages an RF-IC with an integrated antenna (patch antenna), a controlling MCU, and a power supply IC (LDO) into one package.

• All of electric parts are covered with the resin.The RF-IC consists of a semiconductor chip and a dielectric substrate, and the RF circuit is completed within the  semiconductor chip. The dielectric board is configured as part of the antenna and feeders. (Fig.1) The RF-IC’s GND terminals (solder balls) are located at a distance  shorter than the wavelength of 60 GHz and is connected to the solid GND of the printed circuit board. (Fig.2)
  Therefore, the RF circuit has a metal shield structure formed by the RF-IC, GND terminal, and solid GND on the board.

•  The RF signal is in the form of enclosing the feeder line with GND and feeding the antenna with a slot, and has a structure that is completely Metal Shielded.

1.6 Operation Overview

•  +3.6~+5.5 V input operation, LDO integrated.
• All RF controls (Frequency, RF output ON / OFF etc.) in this module are controlled via the built-in microcontroller. The RF-IC cannot be controlled directly from an external device.
• User commands from external devices are processed by the microcontroller.
• The microcontroller controls the RF-IC to modulate at a predetermined frequency according to the command.

(2) This device must accept any interference received, including interference that may cause undesired operation.
RF Exposure Statement for FCC
This equipment complies with radio frequency exposure limits set forth by the FCC for an uncontrolled environment.
This equipment should be installed and operated with a minimum distance of 2.0 cm between the device and the user or bystanders. This device must not be co- located or operating in conjunction with any other antenna or transmitter.

FCC Caution
DC power supply for each module should be conformed to the electrical specifications as described in this section. A host in which a module is integrated should provide  stable DC power through suitable regulator circuit to the module.
As per the FCC rule § 15.255, restrictions are existing for use in a host product.
As per the § 15.255 (a), Operation is NOT permitted for the following products:
(1) Equipment used on satellites.
(2) Field disturbance sensors (FDS), unless the field disturbance sensors are employed for fixed operation.
Note: Fixed FDS is only permitted, Vehicular radar application is NOT permitted under the current FCC rule.
As per the§ 15.255 (b), Operation on aircraft is restricted with specific conditions.
This 60GHz Smart Sensor Micro Module is NOT intended to be used in aircraft.
See the section 6.1 in this manual.

FCC Note:
Changes or modifications to the device not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment(s).
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 by 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 equipment complies with radio frequency exposure limits set forth by the FCC for an uncontrolled environment.

• The device must not be co-located or operating in conjunction with any other antenna or transmitter.

• WARNING:
  The FCC regulations provide that changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment.

• Limitation for use of the modules:
  When the module is installed in a host product, the module shall be connected directly to a PCB of the host product. It shall NOT be extended by any cable. DC power  supply for each module must strictly be conformed to each electrical specification as described in the section 1 of this document.

• Additional testing, Part 15 Subpart B disclaimer
  This modular transmitter is only FCC authorized for the specific rule parts (i.e., FCC transmitter rules) listed on the grant, and each host product manufacturer is responsible for compliance to any other FCC rules that apply to their host device  that is not covered by the modular transmitter grant of certification. Therefore, this  final host product still requires Part 15 Subpart B compliance testing with the modular transmitter installed.

• Manual and Product Labeling information to the End User:
  End user manual must include all required regulatory information and/or warning as show in this manual.
  OEM Integrator must indicate “Contain FCC ID: 2ACUJR4652” at the outside of a host product such as label when the module is installed in the host product.

• The following statement from FCC §15.19(a)(3) is required on the label of the host equipment.
  This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions:
  (1) This device may not cause harmful interference, and
  (2) This device must accept any interference received, including interference that may cause undesired operation.
  OEM Integrator may be sure that the End user manual may not contain any information about the way to install or remove the modules from the host product.
