Product details
Overview
TFF1024HN/N1,135 from NXP Semiconductors is an integrated Ku-band downconverter IC for satellite LNB applications, combining a low-noise pre-amplifier, Gilbert-cell mixer, PLL-based LO synthesizer, and buffer amplifier in a single DHVQFN16 package. It operates across 10.70–12.85 GHz RF input and delivers IF output from 950–2150 MHz with 34.3 dB typical conversion gain, 9.0 dB SSB noise figure, and 18 dBm typical OIP3.
For engineers reviewing the TFF1024HN/N1,135 datasheet, TFF1024HN/N1,135 pinout, TFF1024HN/N1,135 application, or TFF1024HN/N1,135 equivalent, this device serves as a complete RF-to-IF signal chain solution requiring no external LO source, minimal loop filter components, and alignment-free operation in DVB-S/S2 VSAT receivers.
Technical Context
The TFF1024HN/N1,135 integrates a pHEMT-based LNA front-end, double-balanced passive mixer, and fractional-N PLL with integrated VCO operating from 9.75–11.30 GHz. LO frequency is selected via three digital control pins (HB0–HB2), enabling eight discrete crystal-referenced LO settings using a 25 MHz fundamental-mode crystal.
Its architecture supports AC-coupled 50 Ω RF input and 75 Ω IF output interfaces, with on-chip ESD protection on all pins and thermal resistance of 35 K/W. The PLL uses a low-noise loop filter connected between LF (pin 8) and VREG (pin 9), with RMS integrated phase noise of 1.2–2.2 deg (1 kHz–1 MHz offset).
Key Specifications

|---|---|
| RF Frequency Range | 10.70–12.85 GHz - covers full Ku-band satellite downlink spectrum for DVB-S/S2 reception |
| LO Frequency Range | 9.75–11.30 GHz - selectable in 8 discrete steps via HB0/HB1/HB2 pins; crystal-referenced stability |
| IF Output Range | 950–2150 MHz - compatible with standard 75 Ω coaxial IF distribution and demodulator inputs |
| Conversion Gain | 29.8–38.8 dB - high, flat gain enables single-stage IF amplification and simplifies receiver design |
| SSB Noise Figure | 9.0 dB typ. at 1450 MHz IF - meets stringent LNB system noise budget requirements |

Pinout & Package
Package: DHVQFN16 (SOT763-1), 2.5 × 3.5 × 0.85 mm, thermally enhanced with exposed die pad (GND, pin 0).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND (0) | Ground reference and thermal path | Exposed die pad must be soldered to large PCB ground plane for thermal dissipation and RF grounding |
| RF_GND1 (2), RF_GND2 (5), RF_GND3 (1) | RF input ground return | Multiple dedicated RF grounds minimize input impedance discontinuity and improve S11 < −10 dB across band |
| RF (4) | Differential RF input port | 50 Ω CPW-compatible input; requires microstrip transition per Rogers RO4223 layout guidelines |
| HB0 (6), HB1 (13), HB2 (10) | LO frequency selection bits | Three-pin binary interface sets one of eight LO frequencies; open = logic high (1), GND = logic low (0) |
| XO1 (12), XO2 (11) | Crystal oscillator terminals | Connects 25 MHz fundamental-mode crystal (10 pF load); internal PLL generates precise LO |
| LF (8), VREG (9) | PLL loop filter interface | VREG supplies regulated voltage to loop filter; LF connects to filter capacitor/resistor network for stability |
| IF (14) | Single-ended IF output | 75 Ω output drives coaxial cable directly; requires AC coupling and proper termination |
| VCC (16) | Power supply input | Single 5 V supply powers entire signal chain; decoupling to GND pad essential for noise performance |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar satellite LNB downconverter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX2104ETX+T | Requires external LO; lower integration (no PLL/VCO); 3.3 V supply only | Limited to fixed-LO systems; not suitable for multi-band switching without external synthesizer | Select when legacy 3.3 V infrastructure exists and LO flexibility is not required |
| ADL5360ACPZ-R7 | Passive mixer only; no LNA or PLL; 5 V tolerant but no integrated regulation | Demands separate LNA, LO source, and biasing circuitry - increases board area and calibration complexity | Select for ultra-low-noise custom LNB designs where discrete optimization outweighs integration benefits |

FAQ
What is the recommended crystal specification for TFF1024HN/N1,135?
The TFF1024HN/N1,135 requires a 25 MHz fundamental-mode crystal with 10 pF load capacitance and ≤40 Ω ESR. NXP validates performance using low-ESR crystals; deviation beyond these values may degrade phase noise or cause LO unlock. The TFF1024HN/N1,135 datasheet specifies CL = 10 pF and ESR ≤ 40 Ω in Table 8.
How does LO frequency selection work on TFF1024HN/N1,135?
LO frequency is set via three logic pins: HB2 (MSB), HB1, and HB0 (LSB). Each pin is pulled to GND for "0" or left open for "1", selecting one of eight factory-programmed LO frequencies from 9.75 GHz to 11.30 GHz. The TFF1024HN/N1,135 uses internal decoding to configure the PLL divider ratio accordingly, as shown in Table 4.
Can TFF1024HN/N1,135 operate with a 3.3 V supply?
No. The TFF1024HN/N1,135 is specified for 4.5–5.5 V operation only, with 5 V nominal. Supply voltage below 4.5 V risks degraded conversion gain, increased noise figure, and potential PLL instability. The absolute maximum rating is +6 V, but operation outside 4.5–5.5 V voids guaranteed performance per Table 6.
What is the thermal resistance of TFF1024HN/N1,135 and how should it be managed?
The TFF1024HN/N1,135 has a junction-to-case thermal resistance (Rth(j-c)) of 35 K/W. To maintain reliability, the exposed die pad (GND, pin 0) must be soldered to a minimum 100 mm² copper pour on the PCB's inner ground layer, with ≥4 thermal vias (0.3 mm diameter) connecting to internal ground planes. This ensures junction temperature remains within −40 °C to +85 °C ambient limits.
Does TFF1024HN/N1,135 support both horizontal and vertical polarization switching?
Yes. The TFF1024HN/N1,135 itself does not generate polarization control voltages, but its IF output is compatible with standard 22 kHz tone and 13/18 V switching protocols used in dual-polarization LNBs. External circuitry (e.g., voltage regulator and tone detector) handles polarization selection, while the TFF1024HN/N1,135 processes the RF signal regardless of polarization state.
