FP3637-18DP

Antennas RF Overview

The Amphenol PCTEL FP3637-18DP is a dual-polarized directional panel antenna designed for industrial wireless applications. It operates within the 3.30 GHz to 3.80 GHz frequency range, with a center frequency of 3.675 GHz. The antenna provides an 18.5 dBi gain and supports a maximum power handling capacity of 20 W. Key electrical specifications include a typical VSWR of 1.7:1 and a maximum VSWR of 2.0:1. It features linear polarization, a 17-degree beamwidth, and an N-type female connector. The unit measures 40 mm in height and functions reliably between -40°C and +85°C.

Antennas RF Feature Summary

• Dual-polarized directional design optimized for high-gain industrial wireless coverage
• Robust construction supporting extreme operating temperatures from -40°C to +85°C
• Engineered specifically to cover frequencies utilized in industrial wireless networks

Antennas RF Applications

• Industrial wireless communication systems
• Point-to-point or point-to-multipoint links requiring high gain
• Coverage solutions for frequencies between 3.3 GHz and 3.8 GHz

Antennas RF Procurement Notes

Verify that the required frequency band aligns with the 3.30–3.80 GHz operational range. Confirm mechanical mounting requirements match the panel form factor and 40 mm height dimension. Ensure interface compatibility with the N-type female connector on the receiving equipment. Validate environmental ratings against site conditions, specifically the -40°C to +85°C temperature tolerance. Cross-reference technical drawings for precise physical dimensions prior to integration.

Antennas RF Selection Notes

Select this model when high directivity and gain are necessary for long-range industrial links. The dual-polarization capability helps mitigate signal fading in complex environments. Consider the 17-degree beamwidth for focused coverage areas rather than omnidirectional needs. Evaluate the 20 W power rating against transmitter output levels to ensure safe operation. Compare against other VenU series options if different frequency bands or connector types are required.
