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 GSM/UMTS test equipment instead of employing
the SMA antenna connectors on the EHS5-E/EHS5-USR4-DSB75 adapter as shown in Figure 15.
The following products are recommended:
Hirose SMA-Jack/U.FL-Plug conversion adapter HRMJ-U.FLP(40)
