Its robustness and ease of use make it an ideal candidate for the core of any RFID reader application. It is pliant with EPC and ISO standards. Functional Diagram 1 8 7 2 3 Applications - RFID: UHF - Readers - Industrial - Portable WJ’s MH205 uses patented techniques to realize +33 d Bm Input IP3 at an LO drive level of +17 d Bm when used in a simple application circuit as an upconverting or downconverting low-side LO configuration. This single monolithic integrated circuit does not require any external baluns or bias elements. Typical applications include frequency up/down conversion, modulation and demodulation for receivers and transmitters used in various current and next generation RFID technologies such as EPC, ISO, ETSI, and ANSI. Their small size makes them ideal for PCMCIA applications.
