$250-750 USD

Betales ved levering
Increase the range of an NFC antenna on an already existing PCB. Current range is 2.4cm, want to increase to 4cm or more. The antenna trace on PCB can't be changed because of space limitation. NFC is driven using a NXP MFRC630 IC. The range can only be increased by tuning the antenna circuit (see attached schematics) and/or optimizing the MFCR630 registers. A PCB will be provided for testing. Antenna trace can be accessed by removing resistors R10 and R11.

Hi Sir, We have already extended range of some of the RFID readers for clients. WE need to have the design files of PCB so we can make some minor changes, we have to add some amplifiers in the circuit and it will goes upto 10cm. This is one way, sometimes transponder has not max gain set. so we can also exploit that option too. We are professional engineers and developers who do such projects from the last eight years. We offer you our skills for this project at very low rates comparatively without compromising the quality of work. Let me introduce you to our company TURKTRONICS. We are TURKTRONICS. We are professional with 8+ years of experience in Circuit designs, PCB designs, embedded system solutions, mobile app development, programming and software development. We provide complete end to end solutions for all kind of development projects. IOT is our strong point. In this bid, prototyping and shipping cost is not included however paying extra slight of money to include prototypes. We have collaboration with Atechcircuits in Shenzhen China for excellent quality PCB manufacturing. We care about our clients and help them to get out of any potential problem throughout the projects and also give post completion technical support if ever required. We are very much looking forward to hear from you on this in coming days! Cheers!!! Ahmad Lead Technical Engineer TURKTRONICS An Internet of Things Company
