Product details
Overview
QPQ6108TR7 from Qorvo is a Temperature Compensated Surface Acoustic Wave (TC-SAW) FDD duplexer for LTE Band 8, supporting simultaneous uplink (880–915 MHz) and downlink (925–960 MHz) operation with 35 MHz bandwidth, <4.0 dB typical insertion loss, and >50 dB isolation between bands. It enables compact small cell and repeater front-end designs requiring high rejection and low loss without external matching.
For engineers reviewing the QPQ6108TR7 datasheet, pinout, applications, or equivalent options, this page delivers verified electrical specs, validated 9-pin SMP package mapping, real-world RF performance metrics (EVM ≤6.5%, IMD3 ≥−85 dBc), and direct alternatives for Band 8 infrastructure deployments.
Technical Context
The QPQ6108TR7 implements a monolithic TC-SAW filter architecture optimized for FDD LTE Band 8 duplexing, with integrated uplink (UL), downlink (DL), and shared antenna (ANT) ports. Its design achieves temperature-stable passband response across −20°C to +95°C operating range and supports 23 dBm UL / 29 dBm DL CW power handling per life test data.
It operates in single-ended 50 Ω impedance environment, requires no external matching components, and delivers flat group delay (<150 ns variation) and high attenuation (>45 dB) outside Band 8-critical for coexistence in dense RF environments like small cells and LTE dongles.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Frequency Bands | Uplink: 880–915 MHz; Downlink: 925–960 MHz - defines exact LTE Band 8 FDD allocation support |
| Insertion Loss (Typ) | UL: 2.4 dB (885–910 MHz); DL: 3.0 dB (930–955 MHz) - ensures minimal RF path degradation in transceiver chains |
| Isolation (Min) | 50 dB between UL and DL bands - prevents self-interference and enables full-duplex operation |
| Attenuation (Min) | 45–48 dB in adjacent bands (e.g., 832–880 MHz, 980–1000 MHz) - suppresses out-of-band blockers and harmonics |
| EVM (Typ) | ≤6.5% over 5 MHz channels - maintains signal integrity for 16QAM LTE modulation |
| Package Dimensions | 2.00 × 2.50 × 0.87 mm - fits high-density PCB layouts in space-constrained small cell modules |
| Operating Temp | −20°C to +95°C - qualified for outdoor base station and industrial wireless infrastructure |
Pinout & Package
9-pin surface-mount package (SMP) measuring 2.00 mm × 2.50 mm × 0.87 mm, RoHS-compliant and lead-free, with electrolytic NiAu contact plating and MSL Level 3 moisture sensitivity rating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | DL | Downlink RF port - connects to receiver chain input; must be matched to 50 Ω for specified return loss ≥9.5 dB |
| 2, 4, 5, 7, 8, 9 | GND | Ground connections - all six pins require low-inductance PCB grounding for optimal SAW performance and EMI suppression |
| 3 | UL | Uplink RF port - connects to PA output; handles +23 dBm CW per life test at +95°C |
| 6 | ANT | Shared antenna port - bidirectional interface for single-antenna FDD systems; supports both UL transmit and DL receive paths |
Key Features
| Feature | Design Value |
|---|---|
| Temperature Compensation | Stabilizes center frequency drift across −20°C to +95°C, enabling reliable Band 8 operation in uncontrolled outdoor environments |
| No External Matching Required | Integrated impedance tuning eliminates discrete matching networks, reducing BOM count and layout area in front-end modules |
| High Attenuation Outside Band 8 | ≥45 dB rejection in critical adjacent bands (e.g., 832–880 MHz, 980–1000 MHz) prevents interference with GSM and other LTE bands |
| Low Group Delay Variation | <150 ns variation across both UL and DL bands - preserves signal timing integrity for OFDMA-based LTE waveforms |
| Robust Power Handling | Validated for >293,000 hours at +29 dBm DL (+85°C) and +23 dBm UL (+85°C) - meets long-life requirements for infrastructure equipment |

Equivalent & Alternatives
The following parts are listed as comparable options for similar FDD Band 8 duplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| QPQ6107TR7 | Same 2.0×2.5 mm SMP package but rated for −40°C to +105°C extended temperature range; identical Band 8 specs except higher UL power rating (+25 dBm). | Preferred for automotive telematics or harsh-environment base stations where ambient exceeds +95°C. | Select QPQ6107TR7 when extended thermal qualification is required; otherwise QPQ6108TR7 offers cost-optimized performance for commercial infrastructure. |
| B39881B9225Z110 | TDK thin-film BAW duplexer; slightly wider 2.5×2.0 mm footprint; lower DL insertion loss (3.2 dB typ) but narrower UL bandwidth (32 MHz vs 35 MHz). | Better suited for ultra-low-loss receive paths in high-end small cells where UL bandwidth margin is less critical. | Choose B39881B9225Z110 only if system-level testing confirms its narrower UL passband meets application channel plan requirements. |
Compared with QPQ6107TR7 and B39881B9225Z110, the QPQ6108TR7 provides the best balance of bandwidth, isolation, and thermal reliability for mainstream Band 8 small cells and repeaters-without requiring PCB redesign or derating for standard commercial temperature profiles.

FAQ
What is the operating temperature range for the QPQ6108TR7?
The QPQ6108TR7 is specified to operate from −20°C to +95°C. This range is validated per life test data showing >293,000 hours reliability at +85°C under +29 dBm DL and +23 dBm UL CW stress. The device is not rated for −40°C operation; for extended temperature use, Qorvo recommends the QPQ6107TR7 variant instead of the QPQ6108TR7.
Does the QPQ6108TR7 require external matching components?
No, the QPQ6108TR7 does not require external matching components. Its internal TC-SAW design is optimized for 50 Ω single-ended impedance across both UL and DL bands, delivering specified return loss (≥9 dB) and insertion loss without discrete capacitors or inductors-reducing bill-of-materials and layout complexity in front-end modules using the QPQ6108TR7.
What is the meaning of "TR7" in QPQ6108TR7?
The "TR7" suffix in QPQ6108TR7 denotes the tape-and-reel packaging configuration: 2,500 units mounted on a 7-inch reel. This is the standard production packaging format for the QPQ6108TR7, distinct from the QPQ6108SR (100-piece 7″ reel) and QPQ6108EVB (evaluation board). All electrical and mechanical specifications remain identical across these ordering variants of the QPQ6108TR7.
How does the QPQ6108TR7 handle harmonic and intermodulation distortion?
The QPQ6108TR7 demonstrates strong linearity: −100 dBc HD2 at 24 dBm DL CW, −90 dBm IMD2, −85 dBc IMD3, and −110 dBc IMD5 under defined two-tone test conditions. These values ensure minimal spectral regrowth in Band 8 transceivers, preserving adjacent channel leakage ratio (ACLR) and enabling compliant LTE transmission when deployed with the QPQ6108TR7 in the RF front end.
Is the QPQ6108TR7 compatible with lead-free reflow processes?
Yes, the QPQ6108TR7 is fully compatible with lead-free reflow soldering processes up to 260°C peak temperature. Its electrolytic NiAu contact plating and MSL Level 3 moisture sensitivity rating (per IPC/JEDEC J-STD-020) support standard JEDEC-compliant reflow profiles. Tin/lead soldering (≤245°C) is also supported, making the QPQ6108TR7 adaptable to mixed-technology assembly lines.
