GPSMOD2533

Antennas RF Overview

The GPSMOD2533 is an active ceramic patch antenna module manufactured by Pulse Electronics, designed for GNSS applications. It operates at a center frequency of 1.57542 GHz with a maximum frequency of 1.57 GHz. The component provides a gain of 33 dB and maintains a VSWR of 1.5:1 at a 50 Ohm impedance. It supports GPS and GLONASS protocols with right-hand circular polarization (RHCP). The physical dimensions are 25 mm in length and 25 mm in width. It features adhesive mounting and connector termination. The operating temperature range spans from -40°C to +85°C.

Antennas RF Feature Summary

• Active integrated design combining ceramic patch element with low-noise amplifier
• High gain performance optimized for weak signal acquisition
• Compact square form factor suitable for space-constrained PCB layouts
• Adhesive mounting style for rapid assembly without mechanical fasteners

Antennas RF Applications

• Automotive navigation systems
• Portable headsets
• Asset tracking devices
• Positioning modules

Antennas RF Procurement Notes

Verify the specific connector type and cable configuration required for your system integration, as the datasheet indicates connector termination but does not specify the exact interface standard in all contexts. Confirm RoHS compliance status through official documentation prior to procurement. Ensure the adhesive backing is compatible with your substrate material for reliable mechanical attachment during operation within the specified temperature range.

Antennas RF Selection Notes

Select this model when high gain is critical for portable or mobile applications where signal obstruction may occur. The active design reduces cable loss impact compared to passive alternatives. Consider the 25x25mm footprint against available board space. Verify that the connector termination matches your RF chain requirements rather than assuming direct PCB soldering compatibility.

Antennas RF Part Context

This component belongs to the GPSMODxxxx series of active antenna modules from Pulse Electronics. It complements other variants like the GPSMOD1333, which offers similar electrical performance but in a smaller 13x13mm package. The series targets GNSS receivers requiring reliable positioning data in automotive and portable electronics sectors.

Antennas RF Replacement Considerations

GPSMOD1333 serves as a size-reduced alternative with identical electrical specifications including 33 dB gain and 1.57542 GHz center frequency. Verify mechanical fitment due to the dimension difference between 25x25mm and 13x13mm footprints before substitution.
