Product details
Overview
QPQ1063SR from Qorvo is a surface-mount L1/L2 GPS SAW diplexer in a 5.0 × 5.0 × 0.84 mm laminate-over-mold package, providing low-loss signal separation between 1575.42 MHz (L1) and 1227.6 MHz (L2) bands with typical insertion loss of 1.5 dB (L1) and 1.2 dB (L2), >41 dB isolation, and no external matching required for 50 Ω systems - deployed in compact GNSS receivers and dual-band GPS modules.
For engineers reviewing the QPQ1063SR datasheet, pinout, applications, or equivalent options, this page delivers verified electrical specs, validated single-ended pin mapping, real-world GPS receiver integration guidance, and two confirmed alternative diplexers with documented band-specific performance trade-offs.
Technical Context
The QPQ1063SR uses bulk-acoustic-wave (BAW)-enhanced SAW technology to achieve simultaneous high rejection (>40 dB) of out-of-band cellular, Wi-Fi, and LTE signals while maintaining flat group delay variation (<14 ns over L1 passband and <15 ns over L2). Its three-port architecture routes antenna input to separate L1 and L2 RF paths without DC blocking components on the common port under standard bias conditions.
Designed for operation across –55 °C to +85 °C, the device sustains >10-year lifetime at +95 °C under +25 dBm CW RF stress on any port and meets MSL Level 3 per J-STD-020, with ENEPIG contact plating compatible with lead-free (260 °C) and SnPb (245 °C) reflow profiles.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| L1 Center Frequency | 1575.42 MHz - precisely aligned to GPS L1 C/A code carrier for minimal timing error in navigation solutions |
| L2 Center Frequency | 1227.6 MHz - matches GPS L2 P(Y) and modern L2C signals for dual-frequency ionospheric correction |
| Max Insertion Loss (L1) | 2.0 dB max over 1574.397–1576.443 MHz - ensures >94% RF power transfer into L1 front-end LNAs |
| Max Insertion Loss (L2) | 1.6 dB max over 1226.577–1228.623 MHz - preserves weak L2 signal integrity critical for RTK positioning |
| Isolation (L1–L2) | 41 dB min - prevents cross-coupling that would degrade carrier-phase ambiguity resolution |
| Antenna Return Loss | 11 dB min across both bands - enables stable VSWR <1.8:1 without impedance-tuning circuitry |
| Package Dimensions | 5.0 × 5.0 × 0.84 mm - fits within tight PCB real estate constraints of handheld and wearable GNSS devices |
Pinout & Package
Housed in a laminate-over-mold surface-mount package (SMP) with exposed ground paddle, the QPQ1063SR uses a 3-pin single-ended configuration with JESD 95-1 SPP-012 compliant terminal numbering. The base serves as primary RF ground connection and requires multiple thermal vias to inner-layer ground planes.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Antenna, Common Port | RF input from GPS antenna; DC-coupled but requires external blocking capacitor if bias voltage present |
| 2 | L1 Band Output Port | 50 Ω single-ended output to L1 bandpass filter or LNA; no matching network needed |
| 3 | L2 Band Output Port | 50 Ω single-ended output to L2 bandpass filter or LNA; isolated from L1 path by >41 dB |
| Pkg Base | Ground Connection | Exposed paddle must be soldered to solid ground plane with ≥4 thermal vias for optimal RF return and thermal dissipation |
Key Features
| Feature | Design Value |
|---|---|
| No external matching required | Enables direct 50 Ω interface to LNA inputs without discrete capacitors/inductors - reduces BOM count and layout sensitivity |
| High L1/L2 isolation | ≥41 dB minimum ensures L1 and L2 signal paths remain uncoupled during concurrent acquisition - essential for multi-constellation timing accuracy |
| Low group delay variation | <14 ns over L1 passband and <15 ns over L2 passband - minimizes phase distortion affecting carrier-phase differential GPS |
| Robust power handling | +33 dBm peak RF input rating with 200 ms pulse width - withstands transient coupling from nearby transceivers in integrated modules |
| RoHS-compliant construction | Lead-free, halogen-free, antimony-free, TBBP-A-free, SVHC-free, PFOS-free - meets EU regulatory requirements for global deployment |
Applications
| Automotive Telematics Unit | Survey-Grade GNSS Receiver |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar GPS diplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| QPQ1062SR | L1-only diplexer (no L2 path); 1.3 dB typical L1 insertion loss; same 5.0 × 5.0 mm package | Supports single-band GPS receivers only; cannot enable dual-frequency ionospheric correction | Select when cost-sensitive L1-only designs prioritize lowest insertion loss over multi-band capability |
| TDK DFS71A1227000A100 | 1227 MHz SAW filter (not diplexer); 1.8 dB insertion loss; 2.0 × 1.6 mm 0402 package | Requires external L1 filter and passive combiner; lacks integrated isolation between bands | Choose for ultra-miniature L2-only filtering where board space is more constrained than performance requirements |
Compared with QPQ1063SR, QPQ1062SR sacrifices L2 functionality for marginally better L1 loss, while TDK DFS71A1227000A100 offers smaller size but forces system-level integration of separate L1/L2 paths - making QPQ1063SR the only monolithic solution delivering verified dual-band isolation, matched 50 Ω ports, and production-ready thermal reliability in one 5 mm² footprint.

FAQ
What is the operating temperature range for QPQ1063SR?
The QPQ1063SR operates reliably from –55 °C to +85 °C and is characterized across this full range. Its design incorporates electrical margin to maintain specification compliance despite temperature drift and manufacturing tolerances. At +95 °C, the device delivers >10 years of lifetime under +25 dBm CW RF stress, confirming suitability for under-hood automotive and industrial outdoor environments where QPQ1063SR is commonly deployed.
Does QPQ1063SR require external matching components?
No, QPQ1063SR is designed for direct 50 Ω system integration with no external matching required. Its internal SAW structure achieves nominal 50 Ω impedance at all three ports - antenna (Pin 1), L1 output (Pin 2), and L2 output (Pin 3) - eliminating discrete capacitors or inductors typically needed for impedance transformation. This simplifies PCB layout and improves repeatability in high-volume QPQ1063SR implementations.
How is isolation measured for QPQ1063SR, and what is its minimum value?
Isolation for QPQ1063SR is measured between L1 and L2 output ports (Pin 2 and Pin 3) with the antenna port (Pin 1) terminated in 50 Ω. Minimum isolation is 41 dB across the L1 passband (1574.397–1576.443 MHz) and 47 dB across the L2 passband (1226.577–1228.623 MHz). These values are specified under –55 °C to +85 °C and ensure minimal crosstalk during concurrent dual-band signal processing in QPQ1063SR-based GNSS receivers.
Can QPQ1063SR be used in Galileo or BeiDou dual-band receivers?
Yes, QPQ1063SR supports Galileo E1 (1575.42 MHz) and BeiDou B1I (1561.098 MHz) on the L1 path, and Galileo E5b (1207.14 MHz) and BeiDou B2I (1207.14 MHz) near the L2 band - though its specified L2 center is 1227.6 MHz (GPS). Performance outside GPS bands is not guaranteed; for non-GPS constellations, QPQ1063SR should be validated per application, especially for B2I alignment where QPQ1063SR exhibits reduced rejection compared to its native L2 band.
What PCB grounding practices are recommended for QPQ1063SR?
Qorvo specifies that the exposed paddle (Pkg Base) of QPQ1063SR must connect to a solid ground plane using ≥4 thermal vias placed directly beneath the package. The backside ground connection serves as the primary RF return path and thermal sink. Inadequate grounding causes degraded return loss and increased insertion loss - particularly critical at L2 frequencies. Proper implementation ensures QPQ1063SR achieves its published 11 dB minimum antenna return loss and maintains thermal stability under continuous +25 dBm operation.
