Product details
Overview
TFF1012HN/N1,135 from NXP Semiconductors is an integrated Ku-band downconverter IC for satellite LNB applications, combining 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 30 dB typical conversion gain, achieves 9 dB SSB noise figure, and supports dual LO frequencies (9.75 GHz / 10.6 GHz) under 5 V supply with 52 mA typical current draw.
For engineers reviewing the TFF1012HN/N1,135 datasheet, TFF1012HN/N1,135 pinout, TFF1012HN/N1,135 application, or TFF1012HN/N1,135 equivalent, this page provides verified technical context, pin-level design meaning, real-world DVB-S/S2 LNB use cases, and validated alternative options for Ku-band receiver front-end design.
Technical Context
The TFF1012HN/N1,135 integrates a pHEMT-based LNA, double-balanced passive mixer, and fully integrated PLL with crystal-controlled 25 MHz reference and programmable divider to generate precise 9.75 GHz or 10.6 GHz LO signals. Its alignment-free architecture eliminates external tuning components.
It features internal regulated voltage generation for PLL loop filter (VREG pin), HB pin-controlled band switching between low-band (10.7–11.7 GHz) and high-band (11.7–12.75 GHz), and RF/IF ports matched to 50 Ω and 75 Ω respectively - enabling direct interface with CPW-fed antenna inputs and coaxial IF outputs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RF Input Range | 10.7–12.75 GHz (split into low/high bands); enables full Ku-band satellite signal capture per DVB-S/S2 standards. |
| LO Frequency | 9.75 GHz (low band) or 10.6 GHz (high band); selected via HB pin logic, eliminating need for external LO source. |
| Conversion Gain | 30 dB typical; sufficient to drive standard 75 Ω IF distribution without additional amplification. |
| Noise Figure | 9 dB SSB; ensures high signal-to-noise ratio in weak-signal satellite reception environments. |
| Supply Voltage | 4.5–5.5 V; single-rail operation simplifies power design versus multi-voltage LNB solutions. |
| Supply Current | 52 mA typical; enables low-power LNB designs compliant with EN 50494/50600 power-over-coax limits. |
| Crystal Reference | 25 MHz ±10 pF load capacitance; low-cost, industry-standard crystal reduces BOM cost and sourcing complexity. |
Pinout & Package
Package: DHVQFN16 (SOT763-1), 2.5 × 3.5 × 0.85 mm, thermally enhanced with exposed die pad (GND, pin 0) for RF grounding and thermal dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| RF (4) | RF input port | Accepts 10.7–12.75 GHz satellite signal via CPW trace; requires AC coupling and impedance-matched layout to 50 Ω. |
| IF (14) | IF output port | Delivers 950–2150 MHz downconverted signal; designed for direct 75 Ω coaxial cable interface. |
| HB (10) | Band selection control | Logic-level input (0.8 V LOW / 2.0 V HIGH) that switches LO between 9.75 GHz and 10.6 GHz for band selection. |
| XO1 (12), XO2 (11) | Crystal oscillator terminals | Connects to 25 MHz fundamental-mode crystal; internal PLL uses this reference to synthesize exact LO frequencies. |
| VCC (16) | Power supply input | Single 5 V rail powers entire IC including LNA, mixer, PLL, and buffer; decoupling to GND required near pin. |
| GND (0), RF_GND1–3 (1–2,5), GND1 (6), GND2 (13), IF_GND (15) | Ground terminals | Multiple dedicated RF/IF/digital grounds tied to exposed die pad; mandatory for noise suppression and impedance stability. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated PLL + Mixer + LNA | Eliminates discrete LO synthesis, filtering, and amplification stages - reduces PCB area by >40% vs. hybrid solutions. |
| Flat gain over frequency | ±2.0 dB variation across full IF band (950–2150 MHz), ensuring consistent signal level for demodulator AGC stability. |
| Low phase noise (1.4° RMS) | Minimizes constellation rotation in QPSK/8PSK DVB-S2 signals, directly improving BER performance at low C/N. |
| ESD protection on all pins | HBM ≥2 kV on all I/O pins - enables robust handling during LNB assembly and field installation without extra protection devices. |
| Alignment-free concept | No external tuning capacitors or inductors required; production calibration not needed, lowering test time and cost. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar satellite downconverter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX21002ETX+ | Requires external VCO and loop filter; no integrated crystal oscillator; 3.3 V only; smaller 4×4 mm TQFN. | Lacks built-in 25 MHz crystal interface and band-switching logic; needs external tone decoder for HB control. | Select when board space is critical and existing 3.3 V infrastructure exists; accept added component count and layout sensitivity. |
| STV0902B | Separate LNA + mixer + PLL ICs; supports wider 950–2150 MHz IF but no integrated RF input matching network. | Requires external 50 Ω RF balun and IF filtering; higher external component count increases cost and size. | Choose for legacy designs already using ST's satellite tuner ecosystem or where IF flexibility beyond 2150 MHz is required. |
Compared with MAX21002ETX+ and STV0902B, the TFF1012HN/N1,135 offers lowest system-level BOM count and smallest footprint for Ku-band LNBs due to its monolithic integration of crystal oscillator, PLL, mixer, and LNA - reducing design risk and qualification time for DVB-S/S2 compliance.

FAQ
What is the primary function of the TFF1012HN/N1,135 in a satellite LNB system?
The TFF1012HN/N1,135 serves as a fully integrated Ku-band downconverter IC in satellite LNB systems, performing low-noise amplification, frequency mixing, and PLL-based local oscillator synthesis in a single DHVQFN16 package. It converts incoming 10.7–12.75 GHz RF signals to standard 950–2150 MHz IF outputs while maintaining 9 dB noise figure and 30 dB conversion gain - making it central to DVB-S/S2 signal integrity and sensitivity.
How does the HB pin control band selection in the TFF1012HN/N1,135?
The HB (High Band) pin on the TFF1012HN/N1,135 is a digital control input that selects between two LO frequencies: applying a logic HIGH (≥2.0 V) configures the internal PLL for 10.6 GHz LO (high band, 11.7–12.75 GHz RF), while a logic LOW (≤0.8 V) sets 9.75 GHz LO (low band, 10.7–11.7 GHz RF). This enables seamless band switching in tone-controlled LNB systems without external circuitry.
What crystal specifications are required for proper operation of the TFF1012HN/N1,135?
The TFF1012HN/N1,135 requires a 25 MHz fundamental-mode crystal with 10 pF load capacitance and ≤40 Ω ESR, connected between XO1 (pin 12) and XO2 (pin 11). This crystal serves as the reference for the internal PLL, which divides and multiplies to generate precise 9.75 GHz or 10.6 GHz LO frequencies - deviation outside these specs risks LO inaccuracy and degraded phase noise performance.
Can the TFF1012HN/N1,135 operate from a 3.3 V supply?
No, the TFF1012HN/N1,135 is specified for 4.5–5.5 V operation only. Its internal LNA, mixer, and PLL circuits are optimized for 5 V biasing, and operation below 4.5 V may cause gain compression, increased noise figure, or PLL unlock. The datasheet explicitly defines VCC min as 4.5 V, and no 3.3 V characterization data is provided for the TFF1012HN/N1,135.
What thermal considerations apply to the TFF1012HN/N1,135 in sealed LNB housings?
The TFF1012HN/N1,135 has a junction-to-case thermal resistance (Rth(j-c)) of 35 K/W and is rated for operation from −40°C to +85°C ambient. In sealed LNB enclosures, thermal performance depends on soldering the exposed die pad (GND, pin 0) to a large copper pour connected to chassis ground. Without adequate thermal vias and copper area, junction temperature rise may exceed limits during continuous high-gain operation.
