GLHPDM3-SF-MM

Antennas RF Overview

The Amphenol PCTEL GLHPDM3-SF-MM is a broadband RF antenna module designed for multi-standard wireless applications. It operates across five frequency bands centered at 789MHz, 1.5865GHz, 2.205GHz, 2.45GHz, and 5.4GHz. The unit supports LTE, GNSS, Wi-Fi, Bluetooth, and cellular technologies. It features a dome-style form factor with magnetic mounting and includes an integrated low-noise amplifier (LNA). The antenna provides gains ranging from -2dBi to 4dBi depending on the band. It utilizes RP-SMA and SMA connectors and maintains a VSWR of 2. The device is rated for 50W maximum power and offers IP67 ingress protection.

Antennas RF Procurement Notes

Verify that the specific part number matches the required connector configuration, as variations exist between standard and magnetic mount versions within the same series. Confirm that the integrated LNA meets the system's noise figure requirements. Ensure the magnetic mounting surface is compatible with the vehicle or equipment chassis material to maintain secure attachment during operation. Check cable length specifications if remote placement is necessary.

Antennas RF Selection Notes

Select this model when a compact, magnetically mounted solution is required for multi-band vehicle integration. It is suitable for environments demanding high ingress protection and reliable GNSS reception alongside cellular data. Consider the gain variations across bands when planning link budgets. Verify that the RP-SMA and SMA interface types align with existing cabling infrastructure before procurement.

Antennas RF Part Context

This component belongs to the GLHPDLTE-MM series by Amphenol PCTEL, targeting industrial IoT and public safety sectors. It complements other coach-mounted antennas by providing combined LTE, Wi-Fi, and GNSS capabilities in a single housing. The series emphasizes ease of deployment for emergency vehicles and fleet management applications requiring robust wireless connectivity.

Antennas RF Replacement Considerations

GLHPDM3-SF is a related variant but lacks the magnetic mount feature specified in the MM suffix. Verify connector types and mounting hardware compatibility when substituting. Ensure the replacement maintains the required IP67 rating and LNA functionality for equivalent performance.
