1. For RF performance tests a mini-SMT/U.FL to SMA adapter with attached 6dB coaxial attenuator is cho-
sen to connect the evaluation module directly to the UMTS test equipment instead of employing the SMA
antenna connectors on the ELS61-US-DSB75 adapter as shown in Figure 9. The following products are
recommended:
