Improves service coverage and battery life, reduces device temperature.
Quantance addresses the industry wide challenge explained in THE NEED section with an industry-wide solution.
Through proven innovations Quantance can significantly improve cell phone and data card transmit power without increasing battery drain and also provide several other benefits to both wireless product manufacturers and wireless carriers. These benefits are summarized below. For performance characteristics, refer to the PRODUCTS section.
Benefits for Manufacturers and Wireless Carriers
KEY FEATURE |
BENEFIT TO MANUFACTURER |
BENEFIT TO CARRIER |
In HSDPA and HSUPA operation, provides over 2dB peak transmit power increase without increasing battery drain |
No PA back-off required for high speed data like HSDPA or HSUPA, extending wireless phone and data card service coverage and making it more reliable
May allow common PAs to increase power and operate below junction temperature thermal limits |
Improved HSDPA and HSUPA coverage, extending wireless phone and data card service coverage and making it more reliable
Better high speed data coverage (less shrinkage versus Rel.99) without spending capital expense dollars to change infrastructure
Enables carrier to offer extended suite of high speed data applications |
In high power transmit operation, produces the same transmit power for significantly less battery power, or produces 3dB or more transmit power for the same battery power |
Reduces PA current for longer battery life
Reduces thermal problems, enabling smaller, less temperature sensitive wireless phones and data cards |
Longer battery life and fewer drained battery surprises when the wireless phone or data card is operated far from a cell tower
The wireless phone or data card user experiences less heat during use |
Operates on a battery voltage as low as 2.7VDC |
Enables PA circuit to operate over a wider range of battery voltage, thus extending battery life
Supports next generation of smaller, low voltage batteries thus more creative circuit designs and smaller wireless phones and data cards |
Longer battery life
Smaller battery enables smaller wireless phones and data cards |
Can reduce the parts count and height profile of certain transmit circuits |
Reduces bill of material (BOM) cost and circuit size while improving performance |
Enables reduced cost and smaller wireless phones and data cards |
Makes the PA circuit seem like a simple gain block |
Simplifies design process and reduces manufacturing test and calibration time |
Rapid integration cycle |
| Simple, seamless integration |
Quickly adopted into circuit design with minimal impact to existing chipset platform designs |
Rapid integration cycle |
