Notes:
1. Dimensions in mm
2. Gap, G, adjusted so Zo = 50 ohms
3. Ground vias are 0.30, aligned to 0.60 x 0.60 grid
4. Via Boundary rectangle 7.80 x 4.80 centered on device location
5. Ground vias positioned for optimum RF performance, port-to-port isolation, and heat sinking
6. Length of lines extending from all ports, especially Ports 2, 3, and 6, should be minimized to
maintain port-to-port isolation
7. Lines extending from Ports 4 and 5 should preferably be oriented at 90° relative to Ports 2 and
3 to maintain port-to-port isolation
A PCB layout implementing design features similar to
Figure 40 is recommended to optimize performance of
the ACFM-7102.
It is particularly important to maximize isolation between
the Tx connections to the duplexer and the Rx ports. High
isolation is achieved by (1) maintaining a continuous
ground plane around the duplexer mounting area, (2)
surrounding the I/O ports with sufficient ground vias
to enclose the connections in a “Faraday cage” and (3)
preferably routing the Tx traces in a different metal layer
than the Rx traces.
The latter is especially useful, not only to maintain Tx-
Rx isolation of the duplexer, but also to prevent leakage
of the Tx signals into other components that could
result in the creation of intermodulation products and
degradation of overall system performance.
