GPS & Galileo – Dual RF Front-end Receiver and Design, Fabrication, and Test

Measurements (GPS) Part 3

RF Amplifier and Mixer Measurement The RF amplifier and mixer have also been measured on the PCB. In the front-end chip, the measurement has been possible thanks to the intermediate pads located in the input of the mixer’s LO. The input and output are available because they are connected to the external SAW and IF […]

Measurements (GPS) Part 4

IF Amplifier Measurement The measurement of the IF amplifier has also been carried out on a PCB with an encapsulated IC. The connections of the IF amplifier have been made with the pins of the package specially made for the IF filter and the intermediate pads located next to the ADC. Figure 4-28 shows the […]

Measurements (GPS) Part 5

Phase Frequency Detector and Charge Pump Measurement To reduce uncertainties, the static and dynamic behaviour of the PFD and charge pump should also be measured. These can be measured because their input and output are accessible and do not required any extra special pads (other than those already employed) nor a special bonding configuration. The […]

Applications (GPS) Part 1

A number of fields will benefit from a dual GPS/Galileo receiver combined with other technologies. This topic briefly introduces some of the fields and aspects that will be positively impacted by this device. Once the RF front-end has been verified, a system should be developed to check whether the designed RF front-end works for a […]

Applications (GPS) Part 2

Software Navigation software needs to be developed to deal with the information received from the receiver, process that information, and manage both maps and the user interface. The application works with the previously described hardware and processes the data from the GPS receiver and aerial photo maps to provide the user with a visual representation […]

Conclusions (GPS)

The main objective of this topic is to show how to design, fabricate, and test a highly integrated, low-noise, low-power, and low-cost radio frequency (RF) front-end, focusing on the Global Navigation Satellite System (GNSS) standards GPS and Galileo. Starting from the very beginning, this topic spans the entire process, ultimately providing you with everything necessary […]
