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 ELS31-US/ELS51-US-DSB75 adapter as shown in Figure 16. The
following products are recommended:
Hirose SMA-Jack/U.FL-Plug conversion adapter HRMJ-U.FLP(40)

Aeroflex Weinschel Fixed Coaxial Attenuator Model 3T/4T
