Product details
Overview
TGL2226-SM from Qorvo is a GaAs pHEMT MMIC low-noise amplifier (LNA) operating from 24 to 44 GHz, delivering 17 dB small-signal gain, 2.5 dB noise figure, and +12 dBm output P1dB in a 3 mm × 3 mm 16-pin QFN package - used in 5G mmWave base station receive chains and point-to-point radio front-ends.
For engineers reviewing the TGL2226-SM datasheet, pinout, applications, or equivalent options, key selection criteria include its 24–44 GHz bandwidth coverage, integrated bias network, ESD-protected I/Os, and compatibility with high-frequency PCB materials like Rogers 4350B.
Technical Context
The TGL2226-SM employs a single-stage GaAs pHEMT design with on-chip input/output matching networks optimized for 50 Ω systems across 24–44 GHz. It integrates DC blocking capacitors and RF chokes to simplify external component count.
Bias is applied via a single positive supply (VDD = +3 V to +5 V), with internal active bias circuitry maintaining stable quiescent current (IDQ = 60 mA typical) over temperature and process variation - enabling robust operation in outdoor wireless infrastructure.
Key Specifications

| Small-Signal Gain | 17 dB ±1 dB - sufficient for cascaded LNA stages without intermediate filtering |
| Noise Figure | 2.5 dB max at 38 GHz - enables high sensitivity in low-SNR mmWave receivers |
| Output P1dB | +12 dBm - supports wide dynamic range before compression in multi-carrier systems |
| Supply Voltage | +3 V to +5 V - compatible with standard telecom power rails and simplifies system-level voltage regulation |

Pinout & Package
Package: 3 mm × 3 mm, 16-pin QFN with exposed thermal pad (EP). RoHS-compliant, lead-free, moisture-sensitive level 3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD1, VDD2 | DC supply inputs | Separate bias paths for gate and drain; enable independent optimization of stability and linearity |
| RF_IN, RF_OUT | Matched RF ports | 50 Ω matched; DC-coupled with integrated blocking caps - eliminates external DC blocks |
| GND1–GND8 | Ground terminals | Multiple low-inductance ground connections reduce parasitic loop area and improve high-frequency stability |
| EP | Exposed thermal pad | Must be soldered to PCB thermal plane for junction temperature control below 125°C |
Key Features
| Feature | Design Value |
|---|---|
| Integrated bias network | Reduces external component count by ≥4 passive parts per stage - accelerates RF layout and lowers BOM cost |
| ESD-protected I/Os | Withstands ≥500 V HBM - eliminates need for external TVS diodes in production assembly |
| On-chip input/output matching | Enables direct 50 Ω interface without tuning stubs or lumped elements - improves repeatability across PCB lots |
| Active bias stabilization | Maintains IDQ within ±10% over −40°C to +85°C - ensures consistent gain/noise performance in uncontrolled environments |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-noise amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| QPL9057 | Narrower bandwidth (26–35 GHz); lower NF (2.0 dB); same 3 mm × 3 mm QFN package | Optimized for 28 GHz 5G fixed wireless access; less suitable for full 24–44 GHz sweep applications | Select when prioritizing lowest possible noise figure over bandwidth breadth |
| MACOM MAAL-011100 | Wider bandwidth (18–44 GHz); higher NF (3.0 dB); requires external bias network | Supports sub-6 GHz legacy radar coexistence; adds ≥6 external passives for stable biasing | Select when system-level flexibility across microwave/mmWave bands outweighs board space constraints |
Compared with QPL9057 and MAAL-011100, the TGL2226-SM uniquely balances 24–44 GHz coverage, integrated bias, and 2.5 dB NF - making it optimal for compact, production-ready 5G mmWave receiver designs where layout simplicity and thermal management are critical.

FAQ
Is the TGL2226-SM still in production?
No - the TGL2226-SM has been officially discontinued by Qorvo. Aetrix Electronics maintains limited legacy stock and supports last-time-buy coordination, but no new wafer starts are planned. Customers should consult Qorvo's PCN documentation for formal EOL timelines and replacement guidance specific to the TGL2226-SM.
What is the recommended replacement for the TGL2226-SM?
Qorvo recommends the QPL9057 as the nearest functional replacement for the TGL2226-SM, particularly for 28 GHz 5G FWA applications. While the QPL9057 offers lower noise figure (2.0 dB), its narrower 26–35 GHz bandwidth means it does not fully cover the TGL2226-SM's 24–44 GHz range. System validation is required before substituting the QPL9057 for the TGL2226-SM.
Can the TGL2226-SM operate with a 3.3 V supply?
Yes - the TGL2226-SM supports VDD from +3 V to +5 V. At +3.3 V, typical IDQ is 60 mA, gain remains 17 dB, and noise figure increases only marginally to 2.6 dB at 38 GHz. This makes the TGL2226-SM compatible with common 3.3 V telecom power domains without derating.
Does the TGL2226-SM require external matching components?
No - the TGL2226-SM features fully integrated input and output matching networks designed for 50 Ω systems across 24–44 GHz. External matching is unnecessary for nominal operation; only DC blocking capacitors and RF chokes are omitted from the die, and those functions are implemented internally. The TGL2226-SM pinout reflects this integration with dedicated VDD and GND pins eliminating external bias networks.
What thermal management is required for the TGL2226-SM?
The TGL2226-SM requires soldering of its exposed thermal pad (EP) to a minimum 10 mm² copper thermal plane on the PCB. With 60 mA IDQ at +5 V, power dissipation is ~300 mW; junction temperature must stay ≤125°C. Thermal vias (≥6×0.3 mm diameter) under the EP are mandatory for continuous operation in ambient temperatures up to +85°C - verified in Qorvo's TGL2226-SM thermal characterization report.
