Product details
Overview
QPP0020SR 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 rating on Pin4.
For engineers reviewing the QPP0020SR datasheet, pinout, applications, or equivalent options, this component supports broadband RF signal coupling in impedance-matching networks where amplitude/phase balance, low loss, and RoHS-compliant SMT assembly at 260°C are critical design requirements.
Technical Context
This transformer implements a passive flux-coupled magnetic architecture with center-tapped primary (Pins 3–4–5) and secondary (Pins 1–2) windings, enabling balanced-to-balanced 3.06:1 impedance transformation (230 Ω ↔ 75 Ω). It operates without bias and requires no external components.
Designed for fixed-ratio broadband RF coupling, it delivers specified differential return loss ≥−14 dB across 45–1218 MHz and maintains amplitude balance within ±0.1° at 45 MHz and ±0.7° at 1218 MHz, with phase balance tolerance of ±0.5° at low frequency and ±4° at upper band edge.

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, higher insertion loss (>2.0 dB at 250 MHz) | Limited to lower-frequency CATV trunk amplifiers; not rated for >1 GHz operation | Select when cost sensitivity outweighs bandwidth and loss requirements |
| Coilcraft SWA6012-3R06JLT | 3.06:1 ratio, 50–1200 MHz, ±0.3° phase balance at 100 MHz (looser than QPP0020SR's ±0.5° at 45 MHz) | Suitable for general-purpose wireless but lacks QPP0020SR's 600 mA Pin4 current rating for active biasing | Choose when board space allows larger footprint and DC bias feed is not required |
Compared with TC3-25+ and SWA6012-3R06JLT, QPP0020SR uniquely combines 45–1218 MHz coverage, 600 mA center-tap current capability, and tightest low-frequency phase balance - making it optimal for high-density, high-reliability CATV output stages requiring DC bias integration.

FAQ
What is the impedance transformation ratio of the QPP0020SR?
The QPP0020SR provides a fixed 3.06:1 impedance ratio, transforming 230 Ω balanced signals to 75 Ω balanced signals (or vice versa). This ratio is confirmed by electrical specifications and validated across its 45–1218 MHz operating range, enabling direct interface with standard CATV amplifier outputs and 75 Ω coaxial distribution systems without additional matching networks.
Can the QPP0020SR handle DC current on its center tap?
Yes, the QPP0020SR supports up to 600 mA DC current through Pin4 (CENTER PIN) under recommended operating conditions. This allows direct integration into amplifier output stages where the center tap supplies bias current to active devices, eliminating the need for external bias tees or chokes in many CATV and broadband designs.
Is the QPP0020SR compatible with lead-free reflow soldering processes?
Yes, the QPP0020SR is explicitly rated for compatibility with 260°C lead-free soldering profiles and is RoHS compliant per Directive 2011/65/EU as amended by 2015/863/EU. Its tin-plated terminations and SP6 package meet JEDEC J-STD-020 moisture sensitivity level (MSL) requirements for standard SMT assembly.
What does the "SR" suffix indicate in QPP0020SR?
The "SR" suffix in QPP0020SR denotes packaging: 100 pieces supplied on a 13-inch tape-and-reel format. This differs from QPP0020SB (5-piece sample bag) and QPP0020TR13 (1000-piece reel), all sharing identical electrical and mechanical specifications for the QPP0020 transformer core.
How is phase balance specified for the QPP0020SR across frequency?
Phase balance for the QPP0020SR is specified as ±0.5° at 45 MHz and ±4° at 1218 MHz, with linear transitions between measured points. These values reflect differential phase deviation between balanced output terminals under matched 75 Ω load conditions and are verified during 100% RF testing per the datasheet's test methodology.
