In EMMY-W161, the band pass filter (2.4 GHz BPF) is a BAW filter that enables co-existence with
LTE. For the variant EMMY-W165, the band pass filter provides no co-existence protection against
a co-located LTE transmitter.
Figure 2: EMMY-W163 block diagram - Dual-antenna variant
In EMMY-W163, the bandpass filters (2.4 GHz BPF) are ceramic bandpass filters. An LTE co-existence
variant is not available in the dual-antenna configuration.

The EMMY-W161 is recommended for applications that have co-located Wi-Fi, Bluetooth and LTE
antennas and require co-existence of these wireless technologies. This module provides a dedicated BAW
bandpass filter instead of the ceramic bandpass filter. This filter rejects the adjacent LTE bands B40, B7,
B41 and B38. The integrated BAW filter is available only for the single-antenna configuration
(EMMY-W161). The module pinout, operating conditions, and electrical characteristics are identical for all
product variants. Differences in the RF parameters are explained in the Radio specifications section.
