IPS GROUP RFID MODULE

Product Overview:

The IPS RFID Module permits the standalone reader to be remotely located within IPS parking

metering products. The RFID Module is a fully integrated 13.56 MHz RFID analog front end and

data framing reader system.

Key Features:

• • Complete RFID reader system implemented

• • TRF7960 is controlled by the Ultra-low power MSP430 microcontroller

• • On board PCB antenna

• • Independent, on board LED indicators to identify detection of the tags supported.

Antenna Impedance Matching A three element match is used as it has the added advantage of allowing the circuit Q to be a chosen value and unity gain matched. Impedance matching is calibrating the network analyzer. This is done by connecting a RF test connector on three blank circuit boards, one with a 50 load, second with a short (0-Ω resistor), and third with an open. By using the application board in the calibration, PCB parasitic effects are accounted for.
