WebLow Frequency + High FrequencyC: LF + HF cards are the most common dual-frequency cards and usually have an HF antenna laminated around the outside of the card with a thick coil LF antenna contained within. Legacy LF systems like HID prox are often replaced by higher security HF implementations that still require usage of the original LF chip ... WebBoth the TA7642 and the MK484 chips are packaged in a TO-92 case, making it look like a transistor. The following schematic will turn this chip into a functional radio. Part list The first stage of the circuit revolves around U1 (the TA7642 chip) and tunes the resonant frequency to a particular AM broadcast station.
