4 RF Integration
4.1 RF operating frequencies
The FENWAY-2 RF operating frequencies are summarized in Table 4-1.
4.2 RF connections
FENWAY-2 module provides two options for each antenna system interconnect:
 RF Connectors. The primary and secondary, GPS, Bluetooth and WLAN antenna
connector locations are identified in Figure 2-1. Integrated antenna elements can be
connected to the FENWAY-2 module via flexible RF coaxial cables with Murata
model number MM8430 connectors. The FENWAY-2 RF ports are designed to
operate in 50 Ω systems; their inband source and load characteristic impedances are
always 50 Ω nominal. A 10 dB return loss or better should be maintained over all
operating bands throughout the antenna plus cabling systems.
Two additional points are worth highlighting:
 Use short 50 Ω cables for host-to-FENWAY-2 RF interconnections to minimize
loss. Losses between an antenna and the receiver degrade sensitivity; loss in the
transmit path requires additional PA output power (more DC power consumption).
