SX1211 Transceiver module is provided to perform the SX1210 evaluation, it is the receiver part of SX1211
Transceiver with compatible pinout and same receiver performances. SX1211 reference design is given as an
example below. However it is possible to reduce the BOM on SX1210 (refer to Table 29: Reference Design BOM).
The reference design area is represented by the dashed rectangle. C12 is a DC blocking capacitor which protects
the SAW filter. It has been added for debug purposes could be removed for a direct antenna connection if there is
no DC bias is expected at the antenna port. Please note that for SX1210 C10 can be replaced a 5.4nH inductor, L4
by a 0Ohm, L3, C4, R1, C8 and C11 are not used. SAW filter is optional on most application (refer toTable 29:
Reference Design BOM)
As illustrated in figures below, the layout has the following characteristics:
The layers description is illustrated in Figure 45:

ADVANCED COMMUNICATIONS & SENSING
7.5. Reference Design
very compact (9x19mm) => can be easily inserted even on very small PCBs
standard PCB technology (2 layers, 1.6mm, std via & clearance) => low cost
Its performance is quasi-insensitive to dielectric thickness => minimal design effort to transfer to other PCB
technologies (thickness, # of layers, etc...)
