/ 75
Input impedance: 50 Ω
Cable insertion loss:
< 1 dB: LB (<1 GHz)
< 1.5 dB: MB (1–2.3 GHz)
< 2 dB: HB (> 2.3 GHz)
1. It is recommended to use a passive GNSS antenna when LTE B13 or B14 is supported, as the use
of active antenna may generate harmonics which will affect the GNSS performance.
2. Since the GNSS port has a 2.85 V voltage output, a passive antenna that causes shorting to GND,
such as PIFA antenna is not recommended.
5.3. Recommended Mating Plugs for Antenna Connection
EC21 series Mini PCIe is mounted with RF connectors (receptacles) for convenient antenna connection.
The dimensions of the antenna connectors are shown as below.
