GPSMB501 RF Antenna Equivalent & Substitute Parts

Part Overview

The GPSMB501 is a multi-band RF antenna module manufactured by Pulse Electronics, designed for GPS, LTE, and Wi-Fi applications. This SMA Male panel-mount antenna operates across four frequency bands (829MHz, 2.2GHz, 3.2GHz, 5.4GHz) with a 5dBi gain and IP67 ingress protection rating. The product is currently active and ROHS3 compliant. Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained across the specified frequency ranges and termination standards.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the GPSMB501 are qualified based on the following electrical and mechanical parameters:

Frequency Coverage: Substitute antennas must support the primary frequency bands (829MHz, 2.2GHz, 3.2GHz, 5.4GHz) or maintain coverage within the specified frequency ranges (698MHz ~ 960MHz, 1.7GHz ~ 2.7GHz, 2.9GHz ~ 3.6GHz, 4.9GHz ~ 5.9GHz).

Termination Type: All substitutes must feature SMA Male termination to ensure direct mechanical and electrical compatibility with existing connectors.

Mounting Configuration: Panel mount orientation is required to maintain installation compatibility.

Ingress Protection: IP67 rating is maintained across all qualified substitutes to preserve environmental sealing specifications.

Compliance: All substitutes must maintain ROHS3 compliance and active product status.

The four identified substitute parts (MA700.A.ABC.001, MA600.A.ABC.006, MA412.A.BI.003, MA450.K.LBICG.003) meet these criteria with variations in antenna type (dome or flat bar), number of bands, and gain characteristics.

Parameter Comparison

Engineering Selection Recommendations

All four substitute parts maintain active product status and ROHS3 compliance, meeting baseline engineering requirements for direct substitution consideration.

MA700.A.ABC.001 (Taoglas Pantheon Series): Provides dome antenna configuration with six-band coverage including GPS, GLONASS, and LTE. Height exceeds the original module by 9.74mm. VSWR performance ranges from 1.7 to 2, comparable to the original specification. Includes integrated LNA and filter features.

MA600.A.ABC.006 (Taoglas Spartan Series): Offers the broadest frequency coverage with eleven bands supporting CDMA, GLONASS, GPS, GSM, HSPA, UMTS, and Wi-Fi. Dome configuration with three SMA Male terminations. Height of 1.555" (39.50mm) represents a 13.45mm reduction from the original. VSWR of 1.6 to 2 matches original specifications. Includes cable, LNA, and filter features.

MA412.A.BI.003 (Taoglas MA412 Series): Dome antenna with four-band LTE coverage. Smallest profile at 1.220" (31.00mm) height. VSWR of 4.6 exceeds the original specification. Gain not specified in provided data.

MA450.K.LBICG.003 (Taoglas Storm Series): Flat bar antenna with seven-band coverage supporting BEIDOU, GLONASS, GPS, LTE, and WLAN. Dual termination options (RP-SMA Male and SMA Male). Height of 1.219" (30.95mm) provides minimal profile. VSWR of 2 and gain of 4.4dBi approach original performance. Return loss specified at -10dB.

Frequently Asked Questions (FAQ)

Q: Can MA412.A.BI.003 be used as a direct replacement for GPSMB501?

A: MA412.A.BI.003 maintains SMA Male termination, IP67 ingress protection, and panel mount configuration. However, VSWR performance of 4.6 exceeds the original specification of 1.6, and frequency coverage is limited to LTE bands (698MHz ~ 960MHz, 1.71GHz ~ 2.17GHz, 2.49GHz ~ 2.69GHz, 3.3GHz ~ 3.6GHz), excluding the 3.2GHz and 5.4GHz bands of the original module.

Q: What is the primary difference between dome and flat bar antenna types?

A: Antenna type affects physical profile and radiation pattern characteristics. Dome antennas (MA700, MA600, MA412) provide omnidirectional coverage with larger vertical profiles. Flat bar antennas (MA450) offer reduced height with directional characteristics. Selection depends on installation space constraints and coverage requirements.

Q: Does MA450.K.LBICG.003 require connector adaptation?

A: MA450.K.LBICG.003 features dual termination (RP-SMA Male and SMA Male). Direct connection to SMA Male connectors is supported. RP-SMA Male termination is available for alternative connector configurations.

Q: Which substitute provides the closest electrical performance match?

A: MA600.A.ABC.006 provides VSWR of 1.6 to 2, matching the original specification of 1.6, and offers the broadest frequency coverage across eleven bands. MA450.K.LBICG.003 provides VSWR of 2 and gain of 4.4dBi, approaching the original 5dBi specification.

Q: Are all substitutes compliant with environmental and regulatory requirements?

A: All four substitute parts maintain ROHS3 compliance, REACH Unaffected status, and IP67 ingress protection rating, meeting the environmental and regulatory specifications of the original GPSMB501.

Q: What packaging format is available for substitute parts?

A: MA700.A.ABC.001, MA600.A.ABC.006, MA412.A.BI.003, and MA450.K.LBICG.003 are supplied in box packaging. The original GPSMB501 is supplied in bulk packaging.
