SIGEM2M - LOW COST SATELLITE M2M FRONT-END

Objectives

This project focuses on the design of a transceiver for M2M applications at Ku-band. For the transmit part a fully integrated transmitter IC that directly converts an analogue baseband IQ data stream to a Ku-band feed is developed. The receiver part of the system is built around existing LNB components, with an IF L-band output to connect to standard baseband modems. 

Apart from existing M2M applications also the possibility to apply this transmitter in future Ku-band satcom systems is being studied.

Architecture of the fully integrated Ku-band transmitter IC

Challenges

The main challenge of the project is to develop the low-power fully integrated transmitter IC that directly converts an analogue baseband IQ data stream to Ku-band, with sufficient output power to directly connect to the feed of the transmitter.

Benefits

High-level of functional integration can reduce the cost and design effort of future transceiver front-ends, enabling easier access for product manufacturers to enter the M2M market.

Plan

The first phase of the project deals with the high-level performance analysis and architecture trade-off, which will result in a consolidated set of requirements for the transmitter IC development that is taking place in phase 2 of this project. At the end of the project both the receive functionality, using the existing LNB components and the transmitter performance will be demonstrated at breadboard level.

Current status

The project has recently started and the high-level architecture design and trade-off analysis is ongoing.
