5.2. GNSS Antenna Interface

The following table shows frequency specification of GNSS antenna connector.

Table

: GNSS Frequency

1. Keep the characteristic impedance for ANT3_GNSSL1 trace as 50

Ω.

2. Place the

π-type

matching components as close to the antenna as possible.

3. Digital circuits such as (U)SIM card, USB interface, camera module, display connector and SD card

should be kept away from the antenna traces.

4. Keep 75 dB isolation between two antenna traces.

5. Keep 15 dB isolation between each antenna to improve the receiving sensitivity.

5.3. Reference Design of RF Layout

For user’s PCB, the characteristic impedance of all RF traces should be controlled as 50 Ω. The
impedance of the RF traces is usually determi

ned by the trace width (W), the materials’ dielectric constant,

the height from

the signal layer to reference ground (H),

and the space between RF trace and ground (S)
