MCU and DSP features combine in Flash hybrids
The 56F826 and 56F827 are Motorola's newest Flash-based hybrid controllers.
It achieves the desired power control tolerances, while controlling the harmonics and receiver noise that can distort consumers' phone calls.
Additionally, the MMM6025 shrinks the size and improves efficiency over a discrete solution.
This 50ohm transceiver power amplifier module targets worldwide standards for quad- and triband GSM handset applications, functioning over the GSM850, EGSM, DCS, and PCS transmit and receive frequency bands.

Best-in-class claim for new DragonBalls
Motorola claims its two new DragonBall microprocessor products - DragonBall MX1 and DragonBall Super VZ - provide best-in-class handheld performance and battery life.
It is compatible with GSM/GPRS Class 12 operating modes.
By integrating 26 module components into two, this wireless radio front end design integrates power amplifiers, couplers, power detectors, harmonic filters, and antenna switches.
It shrinks the size of the final radio board and end product to help reduce handset costs.
The MMM6025 module accomplishes this by merging many of the critical valued RF capacitor, inductor and coupler functions into the integrated passive devices (IPDs), instead of mounting them as discrete components within the module.
The MMM6025 module increases functionality by eliminating the need for antenna switches and external couplers.
The module contains a small, quad-band, antenna switching function allowing smaller radio boards with greater functionality.
The power amplifier and antenna switch function connects the antenna to the receiver circuitry.
It also develops efficient, high RF power required for reliable communications to the cellular basestations.
This enables increased battery life and talk time for consumers.
"Our competitors' modules do not include the antenna switch or precision power control couplers", said Kent Heath, Director of Cellular Operations for the Radio Products Division of Freescale's Wireless Group.
"Our product provides higher functionality and includes these critical elements - all while reducing the total number of module components designers incorporate into their cellular designs".
Designers can use the MMM6025 as a stand-alone component or they can incorporate it into a cellular platform.
Samples are available now with a suggested resale price of US $2.90 in quantities of 100,000.
