Qorvo RFXF0009H-TR13

Overview

RFXF0009H-TR13 from Qorvo is a 1:1 surface-mount RF transformer optimized for unbalanced-to-balanced signal conversion in broadband RF systems, operating from 45 MHz to 1200 MHz with 75 Ω characteristic impedance, ≤0.8 dB insertion loss (up to 1200 MHz), and ±10° phase balance, deployed in CATV distribution amplifiers and wireless infrastructure front-ends.

For engineers reviewing the RFXF0009H-TR13 datasheet, pinout, applications, or equivalent options, key selection criteria include its 1:1 impedance ratio, 180° nominal phase difference, 2 W RF power handling, −40 to 100°C operating temperature range, and SP5 SMT package compatibility with automated assembly.

Technical Context

The RFXF0009H-TR13 implements a transmission-line-based 1:1 balun architecture with center-tapped secondary winding, supporting differential signaling in RF signal paths where amplitude and phase symmetry are critical. It delivers consistent 75 Ω input/output impedance matching across its full 45–1200 MHz band without external tuning components.

Its unbalanced-to-balanced topology enables single-ended driver interfacing to balanced mixers or ADC inputs while maintaining ≥20 dB input return loss and ≤1.5 dB amplitude balance-key for minimizing even-order distortion in receiver chains and transmitter I/Q paths.

FAQ

What is the maximum RF power rating for RFXF0009H-TR13?

The RFXF0009H-TR13 has an absolute maximum RF power rating of 2 W, validated over its full −40°C to +100°C operating temperature range. This rating supports continuous-wave operation in CATV line drivers and wireless infrastructure power amplifier output stages without thermal degradation. Derating is not required below 100°C ambient, and the device remains within specification up to its storage limit of 100°C.

Does RFXF0009H-TR13 require external DC blocking or biasing components?

No, the RFXF0009H-TR13 is a passive transmission-line transformer with no internal active elements or DC path requirements. It operates transparently across its 45–1200 MHz band without DC blocking capacitors or bias tees. The device supports both AC-coupled and DC-coupled signal paths, provided external circuitry maintains proper RF grounding at Pin 2 (PRIMARY) and avoids DC shorts across the secondary terminals (Pins 3 and 4).

Is RFXF0009H-TR13 compatible with lead-free reflow soldering processes?

Yes, the RFXF0009H-TR13 is fully compatible with standard lead-free reflow profiles, including JEDEC J-STD-020D-compliant peak temperatures up to 260°C. Its SP5 package uses matte tin-plated gull-wing leads and meets RoHS Directive 2011/65/EU and 2015/863/EU requirements. No special pre-bake or moisture sensitivity handling is required prior to assembly.

What does the "DOT" marking indicate on RFXF0009H-TR13 pins?

The "DOT" marking on Pins 1 (PRIMARY DOT) and 3 (SECONDARY DOT) indicates polarity alignment for proper 180° phase inversion. When Pin 1 is driven with a positive-going RF signal, Pin 3 delivers the inverted (180° out-of-phase) output relative to Pin 4. Correct dot-to-dot orientation is essential to maintain intended differential signal polarity in mixer LO or ADC clock paths.

Can RFXF0009H-TR13 be used in 50 Ω systems such as cellular base stations?

The RFXF0009H-TR13 is specified for 75 Ω systems and exhibits degraded return loss and amplitude balance when used in 50 Ω environments. While functional at lower frequencies, its input return loss drops below 15 dB above 200 MHz in 50 Ω configurations. For 50 Ω applications, Qorvo's RFXM0001H or Mini-Circuits ADT1-1WT are better matched alternatives.
