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 ar...

This video introduces two separate, high performance, RF quadrature modulator ICs: the standard CMX993 and the wide bandwidth CMX993W product variant. The CMX993 and CMX993W are integrated, low voltage IQ modulator suitable for use in applications operating from 30MHz to 1000MHz.

The CMX7164 provides 4/16/64-QAM and root-raised-cosine 2/4FSK baseband modem functions in a single chip, replacing the current need for user programmed DSP plus codec ICs. This development includes digital IF filters, auxiliary codecs, clock generator, and I/O functions that lower total BOM cost and chip count.

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...
