RF chipset boosts cordless handset range
SiGe transceiver IC and high-gain power amplifier provide the industry's highest integration level for cordless telephone applications in the 5.8GHz frequency band.
Atmel Corp has a new RF chipset combining the ATR2820 SiGe transceiver IC and the ATR7040 high-gain power amplifier (PA), providing the industry's highest integration level for cordless telephone applications in the 5.8GHz frequency band The ATR2820 fully integrated one-chip 5.8GHz transceiver has been designed using Atmel's advanced SiGe BICMOS process and combines low power consumption and high frequency

Smart MCU aims for point-of-sale control
The AT91SAM9261 smart ARM microcontroller (SAM) is based on the ARM926EJ-S processor and is billed as the industry's first ultra-low-power deterministic microcontroller.
Controller maintains automotive system safety
With its built-in driver functions and complete monitoring system, the ATA6814 is a unique solution beneficial for all safety-relevant automotive electronics.
The new device contains a fully integrated low-IF receiver, VCO, PLL and a transmit output with 3dBm output power.
It is extremely flexible and can be programmed via a three-wire serial bus to integrate with any cordless telephone baseband available on the market as well as standard microcontrollers for gaming and other consumer applications.
The ATR2820's high datarate capability (1.152Mbit/s) allows the support of up to six handsets, using the standard DECT protocol via the same basestation, or more than six game pads with a game controller.
The ATR7040 power amplifier boosts the power to the optimum of 25dBm with a supply voltage of 3.6V.
Taking into consideration the lack of an antenna filter and the transmit/receive switch of 2dB, the coverage distance is about 500m (typically, in free space).
The output power can be increased by applying a higher supply voltage.
The new chipset provides excellent technical performance at the lowest manufacturing cost, two key issues in the consumer electronics market.
The extremely low current consumption (the average RF module consumes 26.5mA with one voice link active) allows cordless phone manufacturers to save cost by using smaller capacity batteries.
Also, the bill of materials, and thus system costs, are low because very few external components are needed to complete a cordless phone design.
The new RF chipset is very production friendly - no software or mechanical tuning is needed.
Simple ISM applications using the ATR2820 as a stand-alone device can be realised on a small two-layer printed circuit board.
Samples of the ATR2820 in QFN32 (5 x 5mm) and the ATR7040 PA in QFN16 (3 x 3mm) packages are available now with pricing starting at US $5.70 for 10,000-piece quantities.
