Solve the exothermic problem completely. No need for connecting any other outer radiating device. It can work without exothermic reaction in the normal indoor temperature. Sustain electricity<200mA @ 3.5V (26 dBm Output). Pulse peak current<260mA。
|
|
|
Outstanding stability: 24 hours x 365days work normally. Appearance little influenced by cover, electromagnetic environment etc. Wide temperature design and the temperature drift coefficient.
|
|
|
Good consistency: Good design in consistency. Choose the top level components to keep each parameters stable and consistence.
|
|
|
Brief and high efficient interface of hardware and software. Peripheral circuit is very easy. The signal power, no need for extra connecting tantalum capacitor.
