Any ICs suggestion for 868MHz Transmitter & Receiver?

[Mac7978]

Hi all,

I am going to design a pair of Tx and RX at 868MHz. Can anyone suggest me a chip for this purpose?

I prefer the chip use ASK as it can save half of power, also the current consumption is as low as possible.

Thank You

Best rgds.

Macccccc

Venture Technologies makes a board with a Micrel RF500 and a microprocessor onboard. Works well.

If you want to go for a standardised solution, try the IEEE 802.15.4 devices:

or ATMEL

chipcon has transceivers some of them are in ZigBee™ family

Yes, but none at 868MHz

All the best

A true single-chip narrowband RF Transceiver
The CC1020 is the industry's first single-chip FSK/ASK CMOS RF transceiver that meet the stringent requirements of multi-channel narrowband applications. The circuit is mainly intended for the ISM (Industrial, Scientific and Medical) and SRD ( Short Range Device) frequency bands at 426, 429, 433, 868 and 915 MHz, but can easily be programmed at other frequencies in the 402-470 and 804-940 MHz range
