W3022 RF Antenna 1.9GHz Chip Solder SMD Equivalent & Substitute Parts

Part Overview

The W3022 is an active production RF chip antenna manufactured by Pulse Electronics, designed for 1.9GHz UHF band applications. This single-band surface mount component operates across the 1.88GHz to 1.93GHz frequency range with 2.5dBi gain and -12dB return loss. The part is packaged in Tape & Reel format with solder termination and maintains ROHS3 compliance with MSL 1 rating. Substitute parts may be required due to inventory constraints, design optimization for alternative frequency bands, or application-specific performance requirements.

Substitute Part Grouping Explanation

Substitute parts for the W3022 are identified based on the following allowable parameters: antenna type (chip), mounting method (surface mount), termination type (solder), packaging format (Tape & Reel), and compliance certifications (ROHS3, REACH Unaffected, EAR99). The three substitute parts listed—PA.12, PA.710.A, and SGP.1575.25.4.D.02—share these core mechanical and compliance attributes with the W3022.

However, substitution is constrained by frequency band requirements. The W3022 operates in the 1.9GHz UHF band. PA.12 operates at 2.4GHz for Bluetooth/WLAN/Zigbee applications. PA.710.A is a multi-band antenna covering 700MHz through 2.6GHz including the 1.9GHz band. SGP.1575.25.4.D.02 is a GPS-specific antenna at 1.575GHz. Direct substitution is only appropriate when the target application's frequency requirements align with the substitute part's operating band.

Engineering Selection Recommendations

All four parts maintain active production status and ROHS3 compliance. The W3022 and SGP.1575.25.4.D.02 share MSL 1 (Unlimited) ratings, indicating superior moisture tolerance compared to PA.12 and PA.710.A, which carry MSL 3 (168 Hours) ratings.

PA.710.A is the only substitute that covers the 1.9GHz band within its multi-band frequency range (1.71GHz ~ 2.17GHz includes 1.88GHz ~ 1.93GHz). This part provides cellular band coverage across 700MHz through 2.6GHz. However, PA.710.A exhibits greater physical height (5.00mm vs. 2.00mm) and lower gain specification at 1.9GHz (3.2dBi vs. 2.5dBi).

PA.12 operates exclusively at 2.4GHz and is suitable only for applications requiring Bluetooth, WLAN, or Zigbee operation. SGP.1575.25.4.D.02 is GPS-specific at 1.575GHz and is not suitable for 1.9GHz applications.

Frequently Asked Questions (FAQ)

Q: Can PA.12 replace the W3022 in a 1.9GHz application?

A: No. PA.12 operates at 2.4GHz (2.4GHz ~ 2.484GHz) and does not cover the 1.9GHz frequency band (1.88GHz ~ 1.93GHz) required by the W3022. Substitution is only valid for applications designed for 2.4GHz Bluetooth, WLAN, or Zigbee operation.

Q: Is PA.710.A a direct replacement for W3022?

A: PA.710.A can substitute for W3022 in 1.9GHz applications because its frequency range (1.71GHz ~ 2.17GHz) encompasses the W3022 operating band (1.88GHz ~ 1.93GHz). However, design considerations include increased height (5.00mm vs. 2.00mm), different gain characteristics (3.2dBi at 1.9GHz vs. 2.5dBi), and reduced moisture sensitivity (MSL 3 vs. MSL 1).

Q: What is the significance of MSL rating differences?

A: MSL 1 (Unlimited) indicates the component can be stored indefinitely without moisture absorption concerns. MSL 3 (168 Hours) requires the component to be used within 168 hours of package opening or requires baking to remove absorbed moisture. W3022 and SGP.1575.25.4.D.02 offer superior shelf-life flexibility compared to PA.12 and PA.710.A.

Q: Can SGP.1575.25.4.D.02 replace W3022?

A: No. SGP.1575.25.4.D.02 is a GPS antenna operating at 1.575GHz (1.564GHz ~ 1.586GHz) and does not cover the 1.9GHz band. Additionally, it is a ceramic patch antenna type rather than a chip antenna, making it unsuitable for W3022 applications.

Q: What packaging considerations apply to these substitutes?

A: All four parts use Tape & Reel (TR) packaging with solder termination and surface mount configuration. Height differences range from 2.00mm (W3022) to 5.38mm (SGP.1575.25.4.D.02). PCB layout and clearance requirements must accommodate the substitute part's physical dimensions.
