Product details
Overview
RFXF0008HSR from Qorvo is a 1:2.78 impedance-ratio, broadband surface-mount RF transformer optimized for balanced-to-balanced signal conversion in 45–1218 MHz applications, with 75 Ω characteristic impedance, ≤2.8 dB insertion loss (max), and ±1.0 dB amplitude balance up to 1218 MHz - deployed in CATV distribution amplifiers and wireless front-end modules.
For engineers reviewing the RFXF0008HSR datasheet, pinout, applications, or equivalent options, key selection criteria include operational bandwidth coverage (45–1218 MHz), amplitude/phase balance tolerance, DC current rating (500 mA center-tap), insertion loss flatness across sub-bands, and SP6 package compatibility with automated SMT assembly.
Technical Context
The RFXF0008HSR implements a transmission-line-based balun architecture with center-tapped primary winding, enabling balanced input/output operation at 75 Ω while maintaining 180° nominal phase difference. Its design targets broadband impedance transformation without external tuning components.
It supports continuous RF power handling up to 2 W and operates across −40°C to +100°C, with validated performance metrics including input return loss ≥11 dB (1000–1218 MHz), phase balance ≤26° (1000–1218 MHz), and DC current capability of 500 mA through the center tap - all specified at 25°C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Frequency Range | 45–1218 MHz - fully characterized band for insertion loss, return loss, amplitude/phase balance per datasheet test conditions. |
| Impedance Ratio | 1:2.78 - transforms 75 Ω unbalanced source to ~209 Ω balanced load (or vice versa) with minimal mismatch loss. |
| Insertion Loss | ≤2.8 dB max (1000–1218 MHz) - defines worst-case signal attenuation in high-frequency CATV/WiFi bands. |
| Amplitude Balance | ±1.0 dB max (600–1218 MHz) - ensures matched signal levels between differential outputs for IQ mixer or ADC driver use. |
| Phase Balance | ≤26° max (1000–1218 MHz) - maintains timing alignment critical for image rejection in direct-conversion receivers. |
| DC Current Rating | 500 mA (center-tap) - supports bias injection into active devices (e.g., LNA, PA) without saturation or heating derating. |
| Operating Temp | −40°C to +100°C - qualified for outdoor broadband node and industrial wireless infrastructure environments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar broadband RF transformer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Mini-Circuits TC4-1T+ | 1:1 ratio, 5–1000 MHz, 50 Ω, ±0.5 dB amplitude balance (≤500 MHz), no center tap. | Limited to 50 Ω systems; unsuitable for 75 Ω CATV or center-tap bias injection. | Select when 50 Ω impedance and absence of DC bias requirement simplify layout. |
| Qorvo RFXM0006HSR | 1:2.0 ratio, 50–1200 MHz, 75 Ω, same SP6 package, 300 mA CT rating. | Narrower amplitude balance spec (±1.5 dB >600 MHz); lower DC current capacity limits PA bias headroom. | Choose if lower impedance transformation ratio and reduced cost offset tighter balance tolerance needs. |
Compared with TC4-1T+ and RFXM0006HSR, the RFXF0008HSR uniquely delivers 1:2.78 transformation, 500 mA center-tap current, and verified 45–1218 MHz performance - making it the only option qualified for DOCSIS 4.0 upstream and high-power CATV node designs requiring both wideband flatness and bias injection capability.

FAQ
What is the maximum RF power rating for the RFXF0008HSR?
The RFXF0008HSR has an absolute maximum RF power rating of 2 W, as specified in the Absolute Maximum Ratings table of its datasheet. This rating applies across the full 45–1218 MHz operating band under continuous wave conditions at ambient temperatures up to +100°C. Exceeding this limit may cause thermal degradation or permanent damage to the magnetic core or windings. The RFXF0008HSR must be operated within this envelope in CATV line drivers and wireless transmitter stages.
Does the RFXF0008HSR support DC bias injection via its center tap?
Yes, the RFXF0008HSR features a center-tapped primary winding rated for up to 500 mA DC current, enabling direct bias injection into active devices such as LNAs or PAs without external chokes. This functionality is confirmed in the Nominal Operating Parameters table and is integral to its use in active CATV amplifiers and WiFi front-end modules. The RFXF0008HSR's center tap (Pin 2) must be decoupled appropriately to maintain RF isolation while delivering stable DC voltage.
Is the RFXF0008HSR pin-compatible with other SP6-packaged Qorvo transformers?
The RFXF0008HSR uses the standardized SP6 package outline, but pin functions are not interchangeable across Qorvo's SP6 transformer family. For example, RFXM0006HSR assigns Pin 2 as secondary common rather than primary center tap. Therefore, the RFXF0008HSR requires dedicated layout - its pinout is unique to its 1:2.78 ratio and center-tap configuration. Always verify pin mapping before board reuse.
What is the characteristic impedance of the RFXF0008HSR and why does it matter?
The RFXF0008HSR has a 75 Ω characteristic impedance, matching standard coaxial cabling and PCB trace impedances used in CATV, DOCSIS, and broadcast video systems. This minimizes signal reflections and VSWR-related losses at interfaces between the RFXF0008HSR and external filters, amplifiers, or antennas. Using a 50 Ω transformer like TC4-1T+ in a 75 Ω system would incur >1.5 dB mismatch loss - a key reason the RFXF0008HSR is specified for infrastructure-grade broadband applications.
Can the RFXF0008HSR be used in DOCSIS 4.0 upstream transmission?
Yes, the RFXF0008HSR is qualified for DOCSIS 4.0 upstream applications up to 204 MHz, with measured insertion loss ≤2.0 dB and input return loss ≥14 dB in that band. Its 45–1218 MHz specification covers the full upstream spectrum (5–204 MHz) and extends into downstream bands, supporting full-duplex operation. The RFXF0008HSR's amplitude balance (<±0.5 dB) and phase stability ensure compliance with DOCSIS 4.0 MER and spectral mask requirements in cable modem RF sections.
