Product details
Overview
QPP0020TR13 from Qorvo is a 3.06:1 flux-coupled balanced-to-balanced RF transformer optimized for CATV amplifier output stages, operating from 45 MHz to 1218 MHz with 75 Ω characteristic impedance, ≤1.5 dB typical insertion loss at 45 MHz, and 600 mA DC current capability on Pin 4.
For engineers reviewing the QPP0020TR13 datasheet, pinout, applications, or equivalent options, this component supports broadband RF signal coupling in impedance-matched 75 Ω systems requiring low phase/amplitude imbalance, high RF power handling (+30 dBm CW), and RoHS-compliant SMT assembly at 260°C.
Technical Context
This transformer implements a center-tapped, flux-coupled magnetic design with isolated balanced ports: primary side (Pins 3 and 5) referenced to 230 Ω, secondary side (Pins 1 and 2) referenced to 75 Ω, and Pin 4 serving as grounded center tap. It delivers differential return loss ≥14 dB across full band and maintains amplitude balance within ±0.1° at 45 MHz.
Phase balance remains within ±0.5° up to 45 MHz but degrades to −4°/+0.5° at 1218 MHz, indicating frequency-dependent common-mode rejection. The SP6 surface-mount package enables automated placement while supporting 100% RF testing and lead-free reflow compatibility.

Equivalent & Alternatives
The following parts are listed as comparable options for similar RF transformer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Mini-Circuits TC3-25+ | 2.5:1 ratio, 5–250 MHz bandwidth, 50 Ω system impedance | Limited to sub-250 MHz; not suitable for full CATV spectrum | Select when lower-frequency 50 Ω systems require higher power handling (1 W) |
| MACOM MAT-03A | 3:1 ratio, 50–1000 MHz, 75 Ω, no center tap (4-pin) | Lacks Pin 4 ground reference - unsuitable for bias-injection architectures | Choose only if center-tap functionality is not required and bandwidth below 1000 MHz is acceptable |
Compared with TC3-25+ and MAT-03A, QPP0020TR13 uniquely supports full 45–1218 MHz CATV spectrum with 75 Ω impedance, center-tapped grounding, and 600 mA DC current-enabling direct integration into modern hybrid fiber-coax amplifier designs without external biasing components.

FAQ
What is the impedance ratio and system impedance of the QPP0020TR13?
The QPP0020TR13 has a fixed 3.06:1 impedance ratio, transforming from 230 Ω balanced (primary) to 75 Ω balanced (secondary). Its characteristic impedance is 75 Ω on the secondary side and 230 Ω on the primary side, making it purpose-built for 75 Ω CATV infrastructure and compatible with standard coaxial test equipment.
Does the QPP0020TR13 support DC current injection, and if so, what is the rating?
Yes, the QPP0020TR13 supports DC current injection via Pin 4 (CENTER PIN), rated for 600 mA continuous DC current at operating temperatures up to +100°C. This enables bias teeing in active CATV amplifier output stages without magnetic core saturation, as confirmed in the Absolute Maximum Ratings table.
What is the package type and mounting compatibility of the QPP0020TR13?
The QPP0020TR13 uses the SP6 surface-mount package per JEDEC MO-229 and JESD 95-1 SPP-012 standards, with gull-wing leads and green index marking. It is compatible with standard 260°C lead-free reflow profiles and automated pick-and-place equipment used in high-volume PCB assembly.
How is the QPP0020TR13 tested, and what performance parameters are verified?
Every QPP0020TR13 unit undergoes 100% RF testing at Qorvo's facility. Verified parameters include differential insertion loss, differential return loss (Ports 1–2 and 3–5), amplitude balance, phase balance, and impedance ratio across 45–1218 MHz - all measured under defined 4-port S-parameter conditions with IDC = 0 mA and T = +25°C.
Can the QPP0020TR13 be used in 50 Ω systems, or is it strictly for 75 Ω applications?
The QPP0020TR13 is designed exclusively for 75 Ω systems: its secondary side is characterized at 75 Ω and primary side at 230 Ω (75 Ω × 3.06). Using it in 50 Ω systems would result in significant mismatch loss and degraded return loss - it is not recommended outside its specified 75 Ω impedance architecture.
