RF Signal Wireless Test Lab

Weekly Report 1:


Familiarize all group members with RF wireless transmission capabilities and components.

RF Signal Wireless Test Lab

  • We met with Graduate Research Assistants and discussed possible objectives as to how we can enhance certain concepts of the original design.

  • Researched devices such as Mixers, Filters, Circuit Designs, Oscillators, Amplifliers, and RF Signal Generators for Base Band Frequency

  • Familiarize ourselves with the actual design and breakdown the frequency receiver/transmitter capabilities for the 900 MHz and 2.4 GHz frequency signals.

  • Arranged lab access hours with Graduate Research Assistants for further weekly meetings.

Communication Systems - Overview





















To information

sink (user)

  • There are 3 basic elements to every communication system:

  • Transmitter: converts the message signal produced by the source of information into a form suitable for transmission over the channel.

  • Channel: physical medium that connects the transmitter and receiver.

  • Receiver: operates on the received signal so as to reconstruct a recognizable form of the original message signal.

Frequency Bands



LOS propagation, cosmic noise

LOS propagation; rainfall attenuation above 10 GHz, atmospheric attenuation because of oxygen and water vapor, high water vapor absorption at 22.2 GHz

Typical Users

VHF television, FM two-way radio, AM aircraft communication, aircraft navigational aids

UHF television, cellular telephone, navigational aids, radar, GPS, microwave links, personal communication systems



0.3-3 GHz

3-30 GHz


Ultrahigh Frequency


Superhigh Frequency

Components used in original design:

  • Amplifier: enhances current signal to allow stronger frequency

  • Filter (low-pass): bypass unwanted high-frequency signals

  • Mixer – combine both base band and oscillated frequency signals into one

  • Oscillator – generates frequency signal for a determined value

  • Signal Generator – provides base band frequency through an external median

Previous Design

  • Current Design is able to transmit a 900 Mhz and 2.4 MHz frequency

  • The 5.7 MHz transmission capability has been redesigned due to excessive voltage provided by power generator/splitter

  • Efficient in providing consistent results for given frequency capabilities

Proposed Design

  • Take the current design layout for the 900Mhz and 2.4 GHz transmission rate and redesign platform onto a PCB( printed circuit board )

  • Modifying current 5.7 GHz transmitter/receiver design onto new model

  • Find a constructive Application process for the given frequencies once implemented onto PCB

The Next Step - Report 2

  • We will have a finished layout of website where all presentations, progress reports, and research papers will be available for viewing

  • Test the 5.7 GHz frequency design to see what improvements can be made

  • Start researching components for proposed PCB model
