Abstract
The present invention is to implement a SOP of a mobile RFID interrogator. The substrate has external connection terminal patterns on a first surface of a substrate and circuit wiring patterns on a second surface of the substrate. a high frequency front-end part, a power amplifier IC, an analog-digital signal processing chip and the like are mounted on the second surface. The high frequency front-end part is to transmit and receive a RFID signal. The power amplifier IC is to output an amplified high frequency transmission signal to the high frequency front-end part. The analog-digital signal processing chip is to output a high frequency transmission signal to the power amplifier IC and process the RFID signal received through the high frequency front-end part, a mold resin is to cover the second surface and components mounted on the second surface for electrical insulation from outside and physical protection from outside.
