Product Specifications

Technical details and manufacturing context for Transmitter (TX) Block

Definition
The Transmitter (TX) Block is a critical functional unit within a Physical Layer (PHY) Transceiver responsible for the transmission path. It performs digital-to-analog conversion, signal modulation, amplification, and conditioning to prepare data for reliable transmission across communication channels such as copper wires, optical fibers, or wireless media.
Working Principle
The TX Block receives digital data from the Media Access Control (MAC) layer. It processes this data through encoding, scrambling, and framing. A digital-to-analog converter (DAC) then transforms the digital stream into an analog waveform. This waveform is modulated (e.g., using PAM, QAM, OFDM) onto a carrier frequency, amplified by a power amplifier to achieve the required transmission power level, and finally filtered to meet spectral masks and reduce out-of-band emissions before being sent to the physical medium.
