RF ICs in RFID Readers: Follow the Transmit and Receive Signal Paths
Working record — September 20, 2026

Guide: https://yenra.com/rf-ics/

Purpose: Read an RFID reader block diagram and explain how the RF components and their tradeoffs affect reception.

Instructions
Work through the steps below with representative evidence. Mark unresolved fields explicitly. Retain source revisions and test records; do not store credentials or sensitive account information in this file.

1. Identify protocol, region, reader/board revision, firmware and antenna arrangement.
Notes / evidence:

2. Mark transmit, antenna and receiver reference planes on a block diagram.
Notes / evidence:

3. Record measured power, losses, isolation, residual leakage and wanted-signal levels with units and conditions.
Notes / evidence:

4. Record sensitivity/error criterion, waveform, data rate, bandwidth, gain/filter/cancellation settings and raw evidence.
Notes / evidence:

5. Check supply/thermal/antenna conditions and exact component documentation; this worksheet is not a circuit or safety specification.
Notes / evidence:

6. List gaps, responsible engineer, repeat-test configuration and changes requiring review.
Notes / evidence:
