System Design
In today’s world of highly integrated RF and mixed-signal systems, it is essential that ICs are designed and specified with a clear understanding of the wider system issues.
RiverBeck has considerable experience working in this context, doing system and subsystem design with an emphasis on RF, analogue, mixed-signal, and basic physical layer DSP design.
Complementing our IC design skills, we can provide high level functional design and modelling in areas such as
- RF receiver and transmitter architecture choices.
- Modulator and demodulator design (digital and analogue).
- Signal path budget analysis (gain, NF, IP3, etc).
- Detailed system and IC specification.
- Design of RF calibration and control algorithms.
- Design for test.
- Advice on product verification and characterisation.
We have direct experience working in many areas including
- RF receivers (low-IF, homodyne, and heterodyne).
- RF transmitters (homodyne, heterodyne, offset-PLL, open-loop modulation).
- FSK digital and analogue modems.
- Keyless entry receivers and transmitters.
- Line drivers and receivers for fibre optic communications.
We have worked on products meeting a wide variety of industry standards including GSM, Bluetooth, WLAN, DECT, DAMPS, IS-95, ADSL, FTTH/FTTA, STM1/4, and POTS.
