Product features

Integrated antenna character:

1. Be sensitive and stable to the tags identify.

2. Stable reading distance 1 meter.

3. Muti-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 (26dBm Output). Pulse peak current<260mA.


Outstanding stability:

1. 24 hours x 365 days 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:

Peripheral circuit is very easy. The signal power, no need for extra connecting tantalum capacitor.


Installation method:

support 5pin WAFER installation.
