UCODE 9xm

9.6.9 Single-slit antenna solution

9.6.9.1 Description

In UCODE 9xm, the test pads TP1 and TP2 can be safely short-circuited to the RF pads (RF1, RF2). See

Figure 6 and Figure 7.

Single-slit antenna enables easier assembly and antenna design. In addition to the standard antenna assembly,

the related increased input capacitance (Table 14) can be used for optimization for different antenna design.
