Product details
Overview
QPQ1297TR7 from Qorvo is a Bulk Acoustic Wave (BAW) duplexer engineered for FDD LTE Band 3 operation, supporting simultaneous uplink (1710–1785 MHz) and downlink (1805–1880 MHz) filtering in a single surface-mount device. It delivers 2.3 dB typical uplink insertion loss, 2.2 dB typical downlink insertion loss, and ≥54 dB isolation between paths - enabling compact small cell and LTE dongle RF front-ends without external matching.
For engineers reviewing the QPQ1297TR7 datasheet, pinout, applications, or equivalent options, this component serves as a drop-in-ready, RoHS-compliant BAW duplexer requiring no external impedance matching, with validated performance across −40°C to +95°C and full characterization for EVM-critical LTE transmission.
Technical Context
The QPQ1297TR7 implements dual-path BAW filter architecture with physically separate uplink and downlink resonator banks integrated into a monolithic 9-pin SMP package. Its internal topology isolates transmit and receive paths while maintaining 50 Ω single-ended impedance at all three ports (B3 UL, B3 DL, ANT), eliminating need for external baluns or matching networks.
It operates exclusively in FDD mode with fixed, non-tunable passbands aligned precisely to 3GPP Band 3 definitions. Performance includes <2.5 dB average insertion loss over both bands, <2.2 dB amplitude ripple, and >50 dB broadband attenuation outside passbands - verified under +24 dBm DL-tone IMD stress and thermal cycling from −40°C to +95°C.

Equivalent & Alternatives
The following parts are listed as comparable options for similar BAW duplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| QPQ1298TR7 | Same 2.0×2.5 mm SMP package but optimized for Band 40 (TDD); no UL/DL separation - incompatible with FDD Band 3 systems | Designed for TDD-LTE infrastructure only; cannot replace QPQ1297TR7 in FDD configurations | Select only when migrating to Band 40 TDD deployments; not a functional substitute for Band 3 FDD |
| B3020 | SAW-based Band 3 duplexer in 2.5×2.0 mm package; higher insertion loss (3.5 dB typ UL), lower isolation (48 dB min), and narrower temp range (−30°C to +85°C) | Suitable for cost-sensitive consumer devices where linearity and extended temperature are secondary | Use where BAW performance is not mandatory; expect reduced ACLR margin and shorter field life above 85°C |
Compared with QPQ1297TR7, QPQ1298TR7 serves a different 3GPP band and modulation scheme, while B3020 trades BAW-level isolation and thermal robustness for lower cost - making QPQ1297TR7 the sole choice for high-reliability Band 3 FDD infrastructure.

FAQ
What is the operating temperature range of the QPQ1297TR7?
The QPQ1297TR7 is rated for continuous operation from −40°C to +95°C, validated under thermal stress testing and life test conditions including +85°C ambient with +30 dBm downlink power injection. This range supports deployment in outdoor small cells and industrial LTE gateways where ambient temperatures exceed standard commercial limits.
Does the QPQ1297TR7 require external matching components?
No, the QPQ1297TR7 does not require external matching components. Its internal BAW structure is designed for 50 Ω single-ended impedance at all ports (B3 UL, B3 DL, ANT), delivering specified insertion loss, VSWR, and isolation without discrete capacitors or inductors - confirmed across full temperature and frequency ranges in Qorvo's reference design.
What is the isolation performance between uplink and downlink paths in the QPQ1297TR7?
The QPQ1297TR7 provides ≥54 dB minimum isolation from 1710–1780 MHz (UL band) and ≥45 dB minimum from 1805–1875 MHz (DL band), with typical values reaching 56 dB and 51 dB respectively. This isolation level prevents receiver desensitization in full-duplex FDD operation and is measured under −40°C to +95°C conditions per Qorvo's datasheet Rev E.
Can the QPQ1297TR7 be used in TDD-LTE systems?
No, the QPQ1297TR7 is designed exclusively for FDD-LTE Band 3 operation and is not suitable for TDD-LTE systems. Its architecture separates uplink and downlink paths physically and electrically; TDD requires time-domain switching on a single path, which this duplexer does not support. Use Qorvo's QPQ1298TR7 or similar TDD-optimized parts instead.
What evaluation board is available for the QPQ1297TR7?
The QPQ1297EVB evaluation board is available for the QPQ1297TR7. It features SMA connectors (Radiall 9602-1111-018), a dedicated PCB layout matching Qorvo's recommended mounting pattern, and is populated with the QPQ1297 duplexer. The board enables RF performance validation including S-parameter measurement, EVM testing, and isolation verification under real-world bias and thermal conditions.
