Transmit Amplifier Circuit
This section takes the output signal from the CY8CLED16P01 chip and amplifies the signal for trans-
mission over the powerline.
Table 2-2. Key Transmit Amplifier Components
Transmit and Receive Coupling Circuit
This circuit couples the signal from the board on to the powerline. On the receive side, the same cir-
cuit couples the carrier on the powerline in to the board rejecting the low frequency content on the
powerline.

Component
These opamp and high gain transistors are used for power amplification
This transistor controls whether transmission is allowed based on the out-
put of the TXDISABLE pin
This inductor along with R2 filters out the higher frequencies
This is the inductor which grounds the low frequency signal and forms a high pass
with C1 and L1
This is the coupling capacitor which couples the communication signal and rejects
the low frequency noise. The voltage rating of this component is an important
parameter.
