Product details
Overview
TFF1013HN/N1,115 from NXP Semiconductors is an integrated Ku-band downconverter IC for satellite LNB applications, combining a low-noise pre-amplifier, mixer, buffer amplifier, and PLL synthesizer in a single DHVQFN16 package. It operates across 10.7–12.75 GHz RF input, delivers 33 dB typical conversion gain, achieves 9 dB SSB noise figure, and supports dual LO frequencies (9.75 GHz / 10.6 GHz) for DVB-S/S2 digital satellite reception.
For engineers reviewing the TFF1013HN/N1,115 datasheet, TFF1013HN/N1,115 pinout, TFF1013HN/N1,115 application, or TFF1013HN/N1,115 equivalent, key selection criteria include its 5 V single-supply operation, 25 MHz crystal-based LO generation, integrated loop filter interface (LF/VREG pins), and RF/IF impedance matching requirements (50 Ω RF input, 75 Ω IF output).
Technical Context
The TFF1013HN/N1,115 implements a fully integrated PLL-based local oscillator with phase-frequency detector (PFD), charge pump, and on-chip regulator - eliminating external VCO and loop filter components. Its RF front-end uses pHEMT technology for low-noise amplification and image-reject mixing, with internal biasing optimized for horizontal/vertical polarization switching via HB pin control.
Conversion is performed between Ku-band RF (10.7–12.75 GHz) and standard IF outputs (950–2150 MHz), with flat gain response and <2.0 dB gain variation over the full IF band. The device features ESD protection on all pins and supports AC-coupled RF/IF interfaces with specified s11/s22 ≤ −10 dB across operational bands.

Equivalent & Alternatives
The following parts are listed as comparable options for similar satellite LNB downconverter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX21002ETJ+T | Higher supply current (75 mA), wider IF output (40–2500 MHz), no integrated PLL - requires external VCO and loop filter | Supports multi-band satellite standards beyond Ku (e.g., C-band), but increases system complexity and BOM count | Select when broader IF bandwidth or external LO control is required; not drop-in for TFF1013HN/N1,115's integrated PLL architecture |
| STV0903B | Single-chip DVB-S2 demodulator with integrated tuner; includes LNB power control and DiSEqC interface - not a standalone downconverter | Targets full receiver SoC integration rather than discrete LNB module use; lacks RF/IF I/O pins for external IF processing | Choose for highly integrated receiver designs where baseband demodulation is co-located; not suitable as direct functional replacement |
Compared with MAX21002ETJ+T and STV0903B, the TFF1013HN/N1,115 uniquely integrates PLL, mixer, and LNA in one 5 V–powered DHVQFN16 device - offering lowest component count and smallest footprint for dedicated Ku-band LNB modules requiring 9.75/10.6 GHz switching.

FAQ
What is the function of the HB pin on the TFF1013HN/N1,115?
The HB (High Band) pin on the TFF1013HN/N1,115 is a logic-level control input that selects between two LO frequencies: a LOW state (≤0.8 V) configures the device for 9.75 GHz LO (low band), while a HIGH state (≥2.0 V) selects 10.6 GHz LO (high band). This enables seamless band switching in Ku-band LNB systems without external hardware reconfiguration. The TFF1013HN/N1,115 uses this pin to route internal PLL dividers and oscillator paths accordingly.
Does the TFF1013HN/N1,115 require an external VCO?
No, the TFF1013HN/N1,115 does not require an external VCO. It integrates a complete PLL synthesizer with phase-frequency detector (PFD), charge pump, and on-chip regulator, using a 25 MHz crystal connected to XO1/XO2 pins to generate the 9.75 GHz or 10.6 GHz LO directly. This eliminates external VCOs, loop filters, and associated matching components - a core feature of the TFF1013HN/N1,115 architecture.
What is the recommended crystal specification for the TFF1013HN/N1,115?
The TFF1013HN/N1,115 requires a 25 MHz fundamental-mode crystal with 10 pF load capacitance and ≤40 Ω equivalent series resistance (ESR). The crystal must be connected between XO1 and XO2 pins, and its stability directly impacts LO phase noise performance (typical integrated phase noise is 1.5°RMS). No TCXO or VCXO is needed - the TFF1013HN/N1,115's internal PLL provides sufficient frequency accuracy for DVB-S/S2 compliance.
Can the TFF1013HN/N1,115 drive a 75 Ω IF output directly?
Yes, the TFF1013HN/N1,115 IF output is designed for 75 Ω impedance matching, as confirmed by s22 ≤ −10 dB across 950–2150 MHz with Z₀ = 75 Ω. The IF pin drives standard coaxial cable interfaces used in satellite receivers without external buffering or impedance transformation. However, AC coupling is mandatory, and proper PCB layout with controlled 75 Ω microstrip is required to maintain return loss and signal integrity.
What thermal considerations apply to the TFF1013HN/N1,115 in sealed LNB housings?
The TFF1013HN/N1,115 uses a DHVQFN16 package with an exposed die pad offering 35 K/W junction-to-case thermal resistance. In sealed LNB housings, thermal performance depends on soldering the exposed pad to a large copper pour connected to chassis ground. At maximum 52 mA supply current and 5 V, power dissipation is ~260 mW; with proper pad thermal vias and PCB copper area, the device sustains operation up to +85°C ambient - validated in NXP's recommended operating conditions.
