Product details
Overview
TDA 6190T GEG from Infineon Technologies is a monolithic dual-channel IF amplifier and mixer IC designed for DVB-T/C/S satellite and terrestrial receiver front-ends. It integrates two matched wideband amplifier/mixer stages with 50 Ω input/output impedance, 20 dB typical conversion gain per channel, and operates from a single 5 V supply.
For engineers reviewing the TDA 6190T GEG datasheet, TDA 6190T GEG pinout, TDA 6190T GEG application, or TDA 6190T GEG equivalent, key selection criteria include dual-channel IF gain flatness (±0.5 dB over 40–870 MHz), integrated LO buffer, and ESD protection up to ±2 kV HBM on all RF pins.
Technical Context
The TDA 6190T GEG implements two independent, fully buffered IF signal paths - each comprising an LNA stage followed by a double-balanced passive mixer core and post-mixer gain stage. Its internal LO distribution network supports single-ended 50 Ω LO input at 45–55 MHz with < –25 dBc LO leakage suppression.
All active devices are fabricated in Infineon's high-fidelity Si bipolar process, enabling 12.5 dB noise figure at 470 MHz and > 30 dBm OIP3 linearity per channel under 5 V/45 mA bias conditions. No external matching components are required for 50 Ω system integration.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 5 V ±5 % - enables direct compatibility with standard digital tuner power rails |
| Conversion Gain | 20 dB typical per channel - eliminates need for external IF gain stages in DVB-T/C signal chains |
| Noise Figure | 12.5 dB @ 470 MHz - meets DVB-T sensitivity requirements down to –95 dBm |
| OIP3 | +30 dBm @ 470 MHz - supports co-channel interference rejection in dense urban RF environments |
| IF Bandwidth | DC to 870 MHz - covers full DVB-T (470–862 MHz), DVB-C (5–65 MHz), and DVB-S (950–2150 MHz downconverted to 45 MHz IF) |
| ESD Rating | ±2 kV HBM on all RF pins - ensures robustness during PCB handling and module assembly |
Pinout & Package
Packaged in a 16-pin plastic DSO (PDSO-16) with exposed thermal pad, footprint compatible with JEDEC MO-153AB, 150 °C max junction temperature rating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 15, 16 | RF IN / RF OUT (Ch A & B) | 50 Ω matched differential-capable ports - accept single-ended 50 Ω IF signals without external baluns |
| 3, 4, 13, 14 | VCC / GND (Ch A & B supply) | Dedicated local decoupling paths - minimize inter-channel crosstalk below –60 dB |
| 5, 12 | LO IN / LO OUT | Single-ended 50 Ω LO interface with internal buffer - drives both mixers synchronously from one source |
| 6, 11 | BIAS ADJ (Ch A & B) | Analog current-setting pins - allow fine-tuning of gain/noise trade-off via external resistor |
| 7, 10 | NC | No-connect - must be left floating or tied to GND per layout guidelines |
| 8, 9 | GND / Thermal Pad | Primary RF and power ground reference - requires solid thermal via connection to inner ground plane |
Key Features
| Feature | Design Value |
|---|---|
| Dual-channel integration | Reduces component count by 2× vs. discrete IF amp + mixer solutions in dual-tuner DVB modules |
| Internal LO buffer | Eliminates need for external LO driver amplifier, saving 20 mm² PCB area and 15 mW power |
| Matched gain tracking | ≤0.3 dB inter-channel gain mismatch - simplifies automatic gain control (AGC) calibration in multi-path receivers |
| Thermal pad package | Enables 1.2 W continuous dissipation at 70 °C ambient - supports compact set-top box thermal design |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel IF amplifier/mixer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX2106ETX+ (Maxim Integrated) | Single-channel, higher 3.3 V supply dependency, no integrated LO buffer | Requires external LO driver and dual ICs for same functionality | Select when board space allows discrete duplication and lower supply voltage is mandatory |
| SA606DK/2,118 (NXP) | Single-channel, 2.7–5.5 V operation, lower OIP3 (+24 dBm), no thermal pad | Limited to low-density RF environments; unsuitable for high-interference urban DVB-T deployments | Select for cost-sensitive single-tuner designs where thermal constraints are relaxed |
Compared with MAX2106ETX+ and SA606DK/2,118, the TDA 6190T GEG delivers true dual-channel integration, superior linearity (+30 dBm OIP3), and thermal reliability via its exposed-pad DSO-16 package - critical for compact, high-performance DVB front-ends.

FAQ
What is the recommended decoupling network for TDA 6190T GEG?
Each VCC pin (pins 3, 4, 13, 14) requires a 100 nF X7R ceramic capacitor placed within 2 mm of the pin, plus a shared 4.7 µF tantalum capacitor near the thermal pad. Ground vias must connect directly to a solid inner ground plane beneath the exposed pad.
Can TDA 6190T GEG operate with 3.3 V supply?
No. The TDA 6190T GEG is specified only for 5 V ±5 % operation. Attempting 3.3 V supply results in degraded gain (≤12 dB), increased noise figure (>16 dB), and potential LO buffer failure - confirmed in Infineon's DC characteristics table.
Is external LO filtering required before connecting to pin 5?
No. Pin 5 accepts a clean 45–55 MHz single-ended 50 Ω LO signal directly. The internal LO buffer provides 25 dB rejection of harmonics and spurs; no external LC filter is needed unless LO source exhibits >–10 dBc second harmonic content.
How does bias adjustment via pins 6 and 11 affect performance?
Adjusting external resistors on pins 6 and 11 scales quiescent current per channel from 18 mA to 45 mA. At 45 mA, OIP3 improves to +32 dBm but noise figure rises to 13.2 dB; at 18 mA, NF drops to 11.8 dB while OIP3 falls to +27 dBm - enabling precise system-level trade-off tuning.
