Product details
Overview
QPP0021TR13 from Qorvo is a 1:1 surface-mount balun designed for RF signal conversion between balanced and unbalanced 75 Ω transmission lines in CATV amplifier input/output stages. It operates from 45 MHz to 1218 MHz, delivers ≤0.65 dB differential-to-single-ended insertion loss at 1218 MHz, maintains ±0.4 dB amplitude balance and ±7° phase balance up to 1218 MHz, and handles +36 dBm CW RF power at 25 °C.
For engineers reviewing the QPP0021TR13 datasheet, pinout, applications, or equivalent options, key selection criteria include its 75 Ω impedance match, SP5 package footprint compatibility, broadband return loss performance (≥−24 dB differential/SE return loss at 45–400 MHz), and suitability for high-reliability CATV and broadband infrastructure designs requiring lead-free assembly.
Technical Context
The QPP0021TR13 implements a passive transmission-line balun architecture with fixed 1:1 impedance ratio and center-tapped balanced port configuration. Its electrical behavior is defined by measured S-parameters across 45–1218 MHz under −15 dBm input power and 25 °C ambient, with ground reference at Pin 2 and 75 Ω reference impedance on all ports.
It supports operation from −40 °C to +100 °C and withstands 260 °C lead-free reflow. Performance specifications-including amplitude/phase balance, return loss, and insertion loss-are validated with linear interpolation between discrete test frequencies and are not guaranteed across full temperature/power ranges.

Equivalent & Alternatives
The following parts are listed as comparable options for similar balun applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Mini-Circuits BAL-CT1-03+ (75 Ω) | Narrower bandwidth (5–1000 MHz), higher insertion loss (0.9 dB @ 1000 MHz), larger 0805 package (2.0 × 1.25 mm). | Not rated for +36 dBm CW; limited to +30 dBm, unsuitable for high-power CATV output stages. | Prefer QPP0021TR13 where >1 GHz coverage, >+30 dBm handling, or SP5 footprint compatibility is required. |
| MACOM MABA-007159-000T00 | 50 Ω impedance (not 75 Ω), narrower bandwidth (50–1000 MHz), no specified phase balance above 800 MHz. | Requires external impedance transformation for CATV use; incompatible with 75 Ω system architecture without matching networks. | Select QPP0021TR13 for native 75 Ω CATV/broadband deployment without design overhead. |
Compared with BAL-CT1-03+ and MABA-007159-000T00, QPP0021TR13 uniquely combines 75 Ω impedance, 45–1218 MHz bandwidth, +36 dBm power rating, and SP5 packaging-making it the only drop-in solution for high-reliability, high-frequency CATV amplifier signal interfacing without impedance conversion or thermal compromise.

FAQ
What is the impedance specification of the QPP0021TR13?
The QPP0021TR13 is a 75 Ω, 1:1 balun with matched impedance on both balanced (Pins 3–4) and unbalanced (Pin 1) ports. This enables direct integration into CATV and broadband coaxial systems without external matching components. All electrical specifications-including return loss and insertion loss-are referenced to 75 Ω, confirming its native compatibility with standard cable infrastructure.
Does the QPP0021TR13 support lead-free reflow soldering?
Yes, the QPP0021TR13 is qualified for 260°C lead-free reflow soldering per JEDEC J-STD-020. Its tin-plated terminations and SP5 package construction ensure reliable wetting and intermetallic formation during standard Pb-free thermal profiles. The device is also RoHS compliant per Directive 2015/863/EU, with full material declarations available upon request.
What is the maximum RF power rating for continuous wave operation of the QPP0021TR13?
The QPP0021TR13 is rated for +36 dBm CW RF power at 25 °C ambient temperature, with derating required above that temperature. At full rated operating temperature (+100 °C), the maximum CW power is +30 dBm. This rating applies to both differential and single-ended ports and is validated per absolute maximum ratings in the July 2023 datasheet Rev. A.
How is the phase balance of the QPP0021TR13 defined, and what is its value at 1218 MHz?
Phase balance for the QPP0021TR13 is defined as the deviation from ideal 180° differential phase between Pins 3 and 4 relative to Pin 1, measured under −15 dBm input at 25 °C. At 1218 MHz, phase balance is specified as +1° to +7°, meaning the actual differential phase falls within 181°–187°, ensuring robust common-mode suppression in high-frequency amplifier stages.
Is the QPP0021TR13 pinout compatible with other SP5-packaged baluns from Qorvo?
Yes, the QPP0021TR13 follows JESD95-1 SPP-012 pin numbering and SP5 mechanical dimensions (3.2 × 2.5 × 1.2 mm), making it mechanically and electrically compatible with other Qorvo SP5 baluns such as QPP0019 and QPP0020. However, impedance (75 Ω vs. 50 Ω) and frequency range differ-always verify electrical specs before substitution.
