The possible inputs into the receiver should be:
RX0 | RX1 |
1 | 2 |
2 | 1 |
2 | 3 |
3 | 2 |
3 | 4 |
4 | 3 |
4 | 5 |
5 | 4 |
Considering to use a DPDT switch(2X2),
in the following constellation:
Taking into account that the cost of the matrix is one of the most important factors in the design, wondered what could be a more efficient constellation and used elements.
Thanks in Advance.

You'll also want to consider that each stage will have some insertion loss and Noise Figure, so cascading them like that might be costly from a performance perspective. If you're looking for switched-diversity gain, you may want to have a receiver connected to each antenna, anyway, to estimate SNR for each, and then switch after either the final LNA or even after the ADC. The cost/performance tradeoff for each approach may be subjective depending on other constraints.
Just something to think about.

Thank you for the fast and insightful comment.
Connecting a receiver to each antenna can not be considered, as the system must be as low cost as possible. As a result, a single 2X2 receiver is planned to be used.
The other parameters of the system will surely be taken into account.
However, first I need to understand the most basic structure and the cost of each such switch.

Can you please explain or provide link about how are you going to use this matrix for DoA? I might help you if I know the scheme.
