885128

Overview

The Qorvo 885128 is a high-power Bulk Acoustic Wave (BAW) band-pass filter designed for signal conditioning in wireless communication systems. It operates at a center frequency of 2442 MHz with a bandwidth of 79 MHz, targeting the 2.4 GHz WLAN and Bluetooth bands. The component provides low insertion loss of 1.3 dB and features extremely steep skirts to ensure high rejection in adjacent LTE and TD-LTE bands. This enables effective coexistence between Wi-Fi and cellular technologies. The device is housed in a compact 5-SMD, No Lead package.

Feature Summary

• High power handling capability suitable for demanding RF environments
• Steep skirt selectivity for superior adjacent band rejection
• Low insertion loss for efficient signal transmission
• Designed for simultaneous operation of WLAN/BT and LTE/TD-LTE

Applications

• LTE/TD-LTE and Wi-Fi coexistence modules
• Smartphone front-end assemblies
• Mobile broadband devices requiring 2.4 GHz filtering
• IoT devices utilizing dual-band connectivity

Procurement Notes

Verify current availability as the component is scheduled for obsolescence. Confirm that the manufacturer has officially discontinued production. Check for any pending Production Change Notices (PCN) regarding end-of-life status. Ensure final design-in decisions account for potential supply constraints due to the discontinuation timeline.

Selection Notes

Select this component when high linearity and steep filtering are required for 2.4 GHz applications. It is appropriate for designs needing robust interference suppression from nearby cellular bands. Consider the 5-SMD package size for space-constrained layouts. Evaluate thermal performance requirements given the high-power BAW construction.

Part Context

This part belongs to Qorvo's portfolio of Bulk Acoustic Wave filters. It addresses the growing need for spectral efficiency in mobile devices where multiple radio standards operate in close proximity. The technology leverages acoustic wave propagation to achieve performance levels difficult to attain with traditional SAW filters.

Replacement Considerations
