4.1.5. RF Cable Soldering
Soldering the RF cable to RF pad of module correctly will reduce the loss on the path of RF, please refer
to the following example of RF soldering.
Figure 50: RF Soldering Sample
4.2. GNSS Antenna Interface
The GNSS part of MC60 supports both GPS and GLONASS systems. The RF signal is obtained from the
GNSS_ANT pin. The impedance of RF trace should be controlled as 50Ω, and the trace length should be
kept as short as possible.
4.2.1. Antenna Specifications
The module can be connected to a dedicated GPS/GLONASS passive or active antenna to receive
GPS/GLONASS satellite signals. The recommended antenna specifications are given in the following
table.
Table 38: Recommended Antenna Specifications
GPS frequency: 1575.42±2MHz
GLONASS frequency: 1602±4MHz
VSWR: <2 (Typ.)
Polarization: RHCP or Linear
Gain: >0dBi
