RECEIVER RF PORT IMPEDANCE MATCHING NETWORK

RX1A± and RX2A± Impedance Matching Network
The ADRV9001 evaluation board uses both the top and bottom layers of the PCB evaluation platform to accommodate two balun footprints.
The 0805 footprint accommodates the high-frequency narrowband baluns, while the backside accommodates the larger DB1627 case-style
transformer.
The PCB traces of the evaluation board are included in the simulation when designing the impedance match.
matching networks specific to the ADRV9001 evaluation board. The component values apply to RX1A± and RX2A±.
RX1B± and RX2B± Impedance Matching Network
Both the RXA and RXB paths share the same input S-parameters. However, given the ball locations of the RXB paths are in an inner row and
column, and the layout of both paths are slightly different, the RXB path has its own distinct impedance matching network different from the
RXA path. On the RXB path, the low-frequency DB1627 case style transformer is located on the top side of the evaluation platform, and the
high-frequency 0805 footprint transformer is located at the bottom of the board. This configuration is the opposite of the RXA path. This is done
to minimize the coupling of the receive paths.
The PCB traces of the evaluation board are included in the simulation when designing the impedance match.
