Radio Basestation on a single PCB

Cambridge Consultants has launched what it claims is the smallest commercially available 2G and 3G small-cell basestation.
Called Sidewinder and aimed at mobile phone communications and professional radio, it is software configurable between GSM/GPRS/EDGE, WCDMA/HSPA+ and other software-defined radio applications.

Sidewinder can operate at any carrier frequency from 375MHz to 4GHz and with a channel bandwidth from 200kHz to 28MHz.
"Available off the shelf, Sidewinder supports GSM link ranges up to and in excess of 40m indoors and 200m outdoors," said the firm. It can be provided either as hardware supplied directly from us, or as a reference design that can be manufactured by licensees."
On the front end there is a flexible radio device from Lime Microsystems, connected to Picochip PC312 femtocell baseband SoC.
It is compatible with Cambridge Consultants' Centaur GSM/EDGE PHY software reference and WCDMA software from Picochip.
