CMX998 Cartesian Feedback Loop (CFBL) Transmitter Product Introduction

The CMX998 is a Cartesian Feedback Loop (CFBL) Transmitter which improves the efficiency and linearity of transmitters for non-constant envelope modulation systems. The CMX998 is an integrated solution for a linear based Cartesian Feedback Loop (CFBL) transmitter. Acting as a direct conversion quadrature mixer from I and Q to RF output, it provides the capability to linearise the Power Amplifier (PA) via feedback from the PA's output. Included are forward and feedback paths; local oscillator circuitry including loop phase control; an instability detector and uncommitted op-amps for input signal conditioning.

‘Starman’ Multiplexing Communications Unit Utilises CML Microcircuit’s Data Modem Design

‘Starman’ Multiplexing Communications Unit Utilises CML Microcircuit’s Data Modem Design
In-Taxi dispatch control systems have traditionally consisted of mobile data units, which exchange dispatch information with the central office using Public Mobile Radio (PMR). Although GPRS can be used as an alternative communication solution, PMR remains the preferred solution as it offers more reliability in a localised area, and is more cost effective for medium and large scale fleets. In such fleets, PMR is used as the primary method of data communications, with GPRS fall-back or out of range.
