Specifications

Chart 1: Module feature


 

 

Adopt RF chip PR9200

 

 

Uses cost-effective UHF RFID chip .

 

 

 

 

Superior read label performance

 

Sensitive and stable on Identifying labels

Small ceramic antenna stable recognition distance 2-3m .

8dBi Circular polarization plate antenna > 10m .

12dBi Linear polarization antenna>15m .

Multi-label recognition performance:>50pcs .

Completely solve the heating problems

 

No ask to with external cooling device.

Chip temperature will not get high even continuously working at full load for long periods

Continuous current <200mA @ 3.5V (26 dBm Output)

Peak pulse current <260mA

 

 

Excellent stability

 

24 hours x 365days working

the shell, electromagnetic environment affect the performance slightly .

Extend temperature design, temperature drift coefficient is very low .

 

 

Excellent consistency

 

Design model for consistency.

Completely selects the highest level components, ensure the stability parameters

 

 

Simple and efficient software and hardware interface

 

 

Compatible with our INDY R2000 series communication interface, easily interchangeable.

The external circuit is extremely simple, single power supply, No ask an external tantalum capacitors. (See Figure 1: reference design circuit)

 

 

supports two installation methods

 

Support RF connectors and FPC connectors installed.

Support surface mount soldering.
