High gain SMA connector 7 in 1 Wifi and Lte Combo Antenna

Product Introduction

1. Centimeter-level high-precision positioning

Supports GPS L1 (1575.42MHz)/L2 (1227.6MHz) + GLONASS G1 (1602MHz), 28±2dB ultra-low noise amplifier (NF≤1.5dB), RTK positioning accuracy ±1cm (requires dual-frequency receiver).

2. Four-channel WiFi 6E concurrency

4×MIMO covers the full frequency band of 2.4/5/6GHz (2400-2483.5/4900-5825MHz), VSWR<2.5, MU-MIMO optimizes high-density device access.

3. Industrial-grade LTE communication

Dual-band 698-960/1710-2690MHz (Band 12/13/5/7), 3dBi gain + VSWR<3.0, ensuring >99.7% connectivity of Cat-M1/NB-IoT devices in -40°C environment.

4. Durable design for extreme environments

IP67 waterproof (IEC 60529) + -40~85°C wide temperature range + 10-55Hz vibration resistance (MIL-STD-810G Method 514.7), 95% humidity tolerance, salt spray test 1000h.

5. Compact engineering structure

25×25×6mm ultra-micro size (tolerance ±0.1mm) + ABS UV-resistant shell, suitable for space-constrained devices (such as drones/AR glasses).

Application scenarios

FAQ

Q: Does the L2 band support Beidou B2?

A:Only supports GPS L2 (1227.6MHz) and GLONASS G1 (1602MHz), Beidou B2 (1207MHz) needs to be customized.

Q: What is the coverage range of the 6GHz band of WiFi 6E?

A:Fully supports bands below 5925MHz, EIRP≤30dBm.

Q: Is the GNSS antenna impedance marked as 500Ω a typo?

A:Confirmed to be 50Ω standard impedance (typo in the specification), verified by VNA measurement (Smith chart, see page 17 of the report).

Q: Can it be adapted to the u-blox F9P receiver?

A:An SMA-J to MCX adapter is required (phase delay <3°), and a reference circuit is provided (document AN-GNSS-028).

Q: Transmission loss of RG174 cable?

A:2.4GHz: 0.24dB/m, 5.8GHz: 0.62dB/m.

Q: Axial requirements for vibration test?

A:Three-axis sine sweep, according to MIL-STD-810G 514.7 Procedure I.

Q: Metal interference compensation on the mounting surface?

A:The GNSS antenna needs to be ≥35mm above the ground plane, and FR4 substrate + ground via array is recommended.
