Brief introduction
Integrated antenna character
1. Be sensitive and stable to the tags identify.
2. Stable reading distance 2-3 meters.
3. Multi-tags identify, >50pcs tags.
4. Reading distance speed, >50pcs/sec.

Solve the exothermic problem completely.
1. No need for connecting any other outer radiating device. It can work without exothermic reaction in the normal indoor temperature.
2. Sustain electricity<200mA @ 3.5V (26 dBm Output). Pulse peak current<260mA.

Outstanding stability:
1. 24 hours x 365days work normally.
2. Appearance little influenced by cover, electromagnetic environment etc.
3. Wide temperature design and the temperature drift coefficient.

Good consistency:
1.the good design in consistency.
2. Choose the top level components to keep each parameters stable and consistence.

Brief and high efficient interface of hardware and software.
1. Peripheral circuit is very easy. The signal power, no need for extra connecting tantalum capacitor.

Installation method: 

support 5pin WAFER installation.
