Before low-power wireless

Wireless communications protocols for WiFi® and cellular networks have defined standards which cause transceivers to consume many times more power while transmitting than receiving. Hence, there has been relatively little research in the area of receiver power efficiency, since the transmit side made up a far bigger proportion of the overall power budget. As a result, receiver architectures have remained largely unchanged for decades.

Demands on low-power wireless

However, new low-power wireless protocols have stricter limits on transmitted power. Hence, for the first time in digital radio communications, wireless protocols caused transceivers to consume more power while receiving than transmitting, with the result that existing low-power radio transceivers have very limited range.

The solution

Cascoda has overcome this problem with a particularly elegant solution, which has received patent grants on three continents. Cascoda has developed a completely new type of receiver architecture, utilizing demodulation and detection techniques that provide a combination of ultra low power consumption and great performance.

Compatible

Cascoda’s new receiver architecture is fully compatible with international wireless standards.
