Product details
Overview
QPP0021SR from Qorvo is a 1:1 surface-mount balun designed for RF impedance transformation and balanced-to-unbalanced signal conversion in CATV amplifier input/output stages. It operates from 45 MHz to 1218 MHz, features 75 Ω characteristic impedance, delivers ≤0.65 dB differential-to-single-ended insertion loss at 1218 MHz, and supports +36 dBm CW RF power at 25°C.
For engineers reviewing the QPP0021SR datasheet, pinout, applications, or equivalent options, key selection criteria include its SP5 package compatibility with 260°C lead-free reflow, amplitude balance ≤1.75 dB up to 45 MHz, phase balance ±7° at 1218 MHz, and guaranteed 100% RF testing per unit.
Technical Context
The QPP0021SR implements a transmission-line-based 1:1 balun architecture optimized for broadband CATV infrastructure. Its balanced port (pins 3–4) and unbalanced port (pin 1) are referenced to 75 Ω, with pin 2 serving as ground reference - enabling direct integration into 75 Ω coaxial signal paths without external matching.
It maintains stable RF performance across −40°C to +100°C operating temperature and supports continuous-wave RF power up to +36 dBm at 25°C. Differential return loss exceeds −24 dB at 45 MHz and −17.5 dB at 800 MHz, confirming robust port match over full band.
Key Specifications

| Frequency Range | 45–1218 MHz: Full operational bandwidth covering CATV downstream (54–1002 MHz) and upstream (5–42 MHz) plus extended spectrum. |
| Impedance Ratio | 1:1, 75 Ω: Enables direct replacement of legacy 75 Ω baluns without impedance transformation circuitry. |
| Insertion Loss | ≤0.65 dB at 1218 MHz: Minimizes signal attenuation in high-frequency CATV node amplifiers and broadband repeaters. |
| Amplitude Balance | ±1.75 dB max at 45 MHz: Ensures symmetrical signal splitting for low-distortion differential drive in amplifier feedback paths. |
| Phase Balance | ±7° at 1218 MHz: Maintains tight 180° differential phase relationship critical for noise cancellation in balanced amplifier topologies. |
| RF Power Handling | +36 dBm CW at 25°C: Supports high-output CATV line drivers and multi-carrier DOCSIS 4.0 amplifier stages. |
Pinout & Package
QPP0021SR uses the industry-standard SP5 surface-mount package (3.2 mm × 2.5 mm × 1.1 mm), RoHS-compliant, tin-plated terminations, compatible with 260°C lead-free reflow profiles. Marking "21" identifies the QPP0021 family on top surface; pin 1 is designated by white index mark per JESD 95-1 SPP-012.

|---|---|---|
| 1 | SECONDARY DOT Output | Unbalanced RF output port (75 Ω), dot-marked for polarity alignment with downstream 75 Ω loads. |
| 2 | SECONDARY Ground | DC and RF ground reference; must be connected to solid ground plane for return path integrity. |
| 3 | PRIMARY DOT Input | Positive leg of balanced RF input (75 Ω); dot-marked to preserve phase orientation in differential pairs. |
| 4 | PRIMARY Input | Negative leg of balanced RF input (75 Ω); paired with pin 3 to form center-tapped transmission line structure. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar balun applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| QPP0022SR | Same SP5 package, 5–1218 MHz range, −40°C to +105°C rating, +33 dBm CW power | Extended low-frequency coverage supports DOCSIS upstream expansion below 45 MHz | Select QPP0022SR when operating below 45 MHz or requiring higher temperature margin |
| TCM1-83X+ | Miniature SMT, 5–1000 MHz, 50 Ω impedance, −30 dB return loss typical at 500 MHz | 50 Ω system impedance; not directly interchangeable in 75 Ω CATV designs without matching | Choose TCM1-83X+ only for 50 Ω wireless infrastructure where 75 Ω compatibility is not required |
Compared with QPP0021SR, QPP0022SR extends low-end frequency response for next-gen DOCSIS upstream while maintaining identical SP5 layout; TCM1-83X+ serves 50 Ω systems but requires impedance adaptation in CATV applications, increasing BOM count and board area.

FAQ
What is the impedance ratio and system compatibility of the QPP0021SR?
The QPP0021SR is a 1:1 balun with 75 Ω characteristic impedance, designed explicitly for 75 Ω coaxial cable systems used in CATV, HFC, and broadband infrastructure. It is not rated for 50 Ω systems, and direct substitution in 50 Ω applications would require external matching networks. All electrical specifications - including return loss and insertion loss - are measured with 75 Ω reference impedance, confirming its native compatibility with SCTE and DOCSIS-compliant equipment.
Does the QPP0021SR support lead-free reflow soldering, and what is its maximum process temperature?
Yes, the QPP0021SR is fully compatible with lead-free reflow soldering processes up to 260°C peak temperature, as confirmed in its datasheet. The device uses tin-plated terminations and meets J-STD-020 moisture sensitivity level (MSL) requirements for standard SMT assembly. Its SP5 package has been qualified for standard reflow profiles without degradation of RF performance or mechanical integrity.
How is the QPP0021SR pinout configured, and what is the significance of the dot marking?
The QPP0021SR has four terminals: pin 1 (SECONDARY DOT Output), pin 2 (GROUND), pin 3 (PRIMARY DOT Input), and pin 4 (PRIMARY Input). The dot marking on pins 1 and 3 indicates polarity alignment - critical for preserving 180° phase relationship in balanced paths. Pin 2 must be connected to a low-inductance ground plane to ensure proper common-mode rejection and return loss performance across the full 45–1218 MHz band.
What is the RF power handling capability of the QPP0021SR, and how does it vary with temperature?
The QPP0021SR is rated for +36 dBm CW RF power at 25°C and +30 dBm under full recommended operating conditions (−40°C to +100°C). Its power derating curve is linear above 25°C, with no specified reduction below 25°C. This makes it suitable for high-output CATV line amplifiers and broadband repeaters where sustained RF power and thermal stability are essential design requirements for QPP0021SR deployment.
Is S-parameter data available for the QPP0021SR, and how can it be obtained?
Yes, S-parameter data files for the QPP0021SR are available upon request from Qorvo's technical support team. These Touchstone (.s2p) files cover the full 45–1218 MHz range and are measured under standard 3-port conditions with 75 Ω reference impedance. Engineers integrating QPP0021SR into simulation tools like ADS or HFSS should contact Qorvo directly or submit a request via www.qorvo.com to obtain calibrated, measurement-based models for accurate system-level analysis of QPP0021SR performance.
