the RF transmission line impedance and frequency range of the UGWSX933SM0033U. These
antennae may not be modified or altered in any way from the original design as represented in the
antenna datasheets as supplied by the manufacturer.The antennas selected have been specifically
tested with the UGWSX933SM0033U, and they are certified through the regulatory agencies in the
US, Canada, and European Union for authorized use.Use of antennas in a platform other than the
antennas selected by Unigen voids the MA grant for that platform.
Regulator Used.
In order to leverage the FCC/IC modular approval, the host system/system integrator must use the
XC6204B302MR (Mfg: Torex: 3.0V fixed regulator SOT23-5 package) regulator.
Antenna Interconnect & Impedance
Unigen has pre-qualified antennas that integrate the connectors, transmission line and the antenna.
UGWSX933SM0033U requires the use of a ½ wavelength dipole, 902-928MHz frequency range, with
a VSWR no greater than 2.0 and having a maximum output no greater than +2dBi The transmission
line must be designed to be 50-Ohm impedance.
Physical Implementation
The physical implementation of the RF transmission line must conform to the following
guidelines:
• Coaxial Cable: A coaxial of varying length may be used providing the impedance
measures 50 +/- 2 ohms and is non-radiating. Best practice RF engineering suggests
the cable should be kept to the minimum length required to satisfy the application.
Excessive cable and interconnect loss may adversely effect the effective transmission
and reception range of the end product.
Emissions Compliance Testing
The end-product configuration must meet digital emissions compliance and must be tested in
accordance with the European Union standards ETSI 300 328 and ETSI 300 826
(Electromagnetic Compatibility). Detailed European Union documents may be obtained from
the web location:
http://europa.eu.int/comm/enterprise/rtte/infor.htm
These emissions tests can be conducted by the manufacturer or by contacting an approved
test facility equipped and certified accordingly. The results of these emissions tests are not
required to be submitted to the FCC or Unigen, but should be kept on file by the OEM.
Note:
The European Union generally follows the guidelines of the FCC for emissions level
