7.4.1. GNSS RF Front End Design
The LM960 contains an integrated LNA and pre-select SAW filter.
This allows the module to work well with a passive GNSS antenna. If the antenna cannot
be located near the LM960, then an active antenna (that is, an antenna with a low noise
amplifier built in) can be used with an external dedicated power supply circuit.
GNSS rescive path uses either the dedicated GNSS connector or the shared Secondary
#0 antenna connector.
NOTE – Please refer to the LM960 AT Commands Reference Guide,
80568ST10869A for detailed information about GNSS operating
modes and GNSS Antenna selection.
Antenna connection
7.5.1. Support bands in antenna port
The LM960 has an assigned band depending on the antenna port.
The supported bands are:
 Primary RF antenna #0: B1, B2(B25), B3, B4(B66), B5(B26,B18,B19), B8,
B12(B17), B13, B14, B20, B28, B29, B39, B71, B41 for 4 x 4 MIMO
 Primary RF antenna #1: B7, B30, B32, B38, B40, B41, B42, B43, B46, B48,
B2(B25) for 4 x 4 MIMO, B4(B66) for 4 x 4 MIMO
 Secondary RF antenna #0: B1, B2(B25), B3, B4(B66), B5(B26,B18,B19), B8,
B12(B17), B13, B14, B20, B28, B29, B39, B71, B41 for 4 x 4 MIMO / GNSS
 Secondary RF antenna #1: B7, B30, B32, B38, B40, B41, B42, B43, B46, B48,
B25(B2) for 4 x 4 MIMO, B66(B4) for 4 x 4 MIMO
 GNSS antenna: Dedicated GNSS
