Antenna
The antenna is to be implemented in PCB trace (IFA type) and tuned for the
2.4GHz Band.
The antenna system efficiency measurements are carried out in a scattered
field chamber. The antenna system efficiency, ??, is the ratio of the power
delivered at the 50Ω antenna interface, ??, relative to the power radiated
from the antenna, ?????????. ??=???????????
The antenna system efficiency can be expressed in dB or %, where 100% corresponds to 0dB.
| Antenna system efficiency Freq [Mhz] | Antenna efficiency [dB] |
|---|---|
| 2405 | -8.4 |
| 2440 | -4.1 |
| 2480 | -6.3 |
The antenna efficiency is in the order of -5.5 to -6dB with the USB dongle positioned in a computer laptop.
The maximum antenna peak gain is measured to be:
- USB dongle as stand-alone: -2.3dBi
- USB dongle positioned in a Lenovo laptop, display closed: +0.2dBi
- USB dongle positioned in a Lenovo laptop, display open: -0.2dBi
ESD Protection
- The unit is equipped with a TVS protection circuit on the USB interface.
- VBUS and data +/- lines is protected up to 8KV (contact) according to IEC 61000-4-2, level 4 (ESD)
Power Management Unit
The Bluetooth SoC DA14695 has a completely integrated Power Management Unit
(PMU). With several LDOs for the different power rails of the system
Printed Circuit Board
The PCB is a four-layer printed circuit board on FR4 material, gold plated.
Enclosure
Plastic material assembled in two parts in PBT + 20% glass fiber.
Marking information

FCC Part 15.247
This device complies with Part 15 of the FCC 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 undesired operation.
Changes or modifications to this unit not expressly approved by the party
responsible for compliance could void the user’s authority to operate the
equipment.
NOTE : This equipment has been tested and found to comply with the limits
for a Class B digital device, under 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 per 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 the receiver.
- Connect the equipment to 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.
