QPQ1290 Band 41 Tx / Rx Filter Product Overview The QPQ1290 is a high-performance Bulk Acoustic Wave (BAW) Tx/Rx filter designed to meet the strict LTE rejection requirements for use in B41. QPQ1290 is specifically designed to meet the high- performance expectations of insertion loss and rejection for LTE transmit systems under all operating conditions. The QPQ1290 uses common module packaging techniques to achieve the industry standard 1.8x1.4x0.73mm footprint. 8-Pad 1.8 mm x 1.4 mm x 0.73 mm Package Key Features Highly Selective BAW Filter Achieving Low Insertion Loss Over Full Bandwidth and Operating Conditions Excellent Wi-Fi Rejection Functional Block Diagram Performance 20 to +85C RoHS compliant (2002/95/EC), Pb-free B41Tx Input P / Rx Output GND b GND 1 8 7 D D GN 2 6 GN 4 GND 3 5 Applications GND B41Ant Full Band 41 TD-LTE Tx / Rx Top View Pin Configuration - Single Ended Ordering Information Pin No. Label - Function Part No. Description 1 B41 Tx Input/Rx Output QPQ1290TR7 7 Taped Reel with 2500 pieces 5 B41 Ant - Antenna Port QPQ1290-EVB Assembled Evaluation Board 2, 3, 4, 6, 7, 8 GND - Ground Connection* *Note: see application section for details on optimal grounding Datasheet, March 5, 2018 Subject to change without notice 1 of 8 www.qorvo.com QPQ1290 Band 41 Tx / Rx Filter Absolute Maximum Ratings Recommended Operating Conditions Parameter Rating Parameter Min Typ Max Unit Operating Temperature 20 to +85C TCASE -20 +85 C Electrical specifications are measured at specified test conditions.
