Product details
Overview
TGL2767 from Qorvo is a GaAs pHEMT-based voltage-variable RF attenuator operating from 2–25 GHz, delivering >20 dB attenuation range with <2 dB insertion loss in the reference state, and fully matched to 50 Ω for radar, EW, and satellite communication front-ends.
For engineers reviewing the TGL2767 datasheet, pinout, applications, or equivalent options, this device requires attention to control voltage (0–1.5 V), reference voltage (1.5 V), thermal resistance (40 °C/W), IIP3 performance across attenuation states, and die-level mounting constraints for RF stability and reliability.
Technical Context
The TGL2767 implements a monolithic GaAs pHEMT architecture optimized for broadband analog attenuation control without internal biasing circuitry-requiring external VS = 1.5 V and VC ≤ VS for linear attenuation response. Its 4-terminal configuration separates RF path (pins 1 & 4) from dual-voltage control (pins 2 & 3), enabling precise gain management in signal chains where dynamic range and harmonic suppression are critical.
Performance remains stable across –40 to +85 °C ambient, with input/output return loss >12 dB over full band and IIP3 exceeding 38 dBm at 0 dB attenuation (2 GHz, 10 MHz tone spacing). Thermal design must account for θJC = 40 °C/W and mandatory AuSn solder reflow per assembly notes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Frequency Range | 2–25 GHz - supports single-component coverage of S-, C-, X-, Ku-, K-, and Ka-band systems without band switching. |
| Attenuation Range | 20 dB - enables precise RF power leveling across wide dynamic ranges in receiver AGC and transmitter output control loops. |
| Reference State IL | <2.0 dB - minimizes signal degradation when maximum system gain is required, preserving SNR in low-noise paths. |
| Control Voltage | 0.0–1.5 V - compatible with standard DAC outputs and low-voltage analog controllers without level-shifting circuitry. |
| IIP3 (0 dB Att.) | >38 dBm @ 2 GHz - maintains linearity under high-input conditions typical in radar pulse amplification and broadband instrumentation. |
| Thermal Resistance θJC | 40.0 °C/W - dictates minimum heatsinking requirements when dissipating up to 1 W under high-power RF operation. |
| Die Size | 1.17 × 0.98 × 0.10 mm - ultra-compact bare-die form factor requiring precision flip-chip or epoxy-mount assembly on RF substrates. |
Pinout & Package
Package: Bare die (1.17 × 0.98 mm, 0.10 mm thick), gold metallization, backside ground, RoHS-compliant, lead-free/halogen-free.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | RF Input | 50 Ω AC-coupled RF port; requires external DC blocking and impedance-matched microstrip launch for minimal mismatch. |
| 2 | VC | Control voltage input (0–1.5 V); sets attenuation level relative to VS; sensitive to noise-requires local decoupling. |
| 3 | VS | Reference voltage (1.5 V fixed or adjustable); establishes baseline FET threshold compensation across process variation. |
| 4 | RF Output | 50 Ω AC-coupled RF port; output return loss >12 dB ensures minimal reflection into downstream stages like mixers or ADC drivers. |
Key Features
| Feature | Design Value |
|---|---|
| Monolithic GaAs pHEMT Process | QPHT15 0.15 µm process delivers consistent high-frequency performance and thermal stability across wafer lots. |
| 50 Ω Matched Ports | Eliminates need for external matching networks-reducing board area, insertion loss, and tuning complexity in multi-GHz designs. |
| Wideband Linearity Control | IIP3 >22 dBm maintained across 5–20 dB attenuation states, enabling predictable distortion behavior in variable-gain receivers. |
| Low-Temp Coefficient Attenuation | Relative attenuation drift < ±0.5 dB over –40 to +85 °C, supporting stable gain control in unheated outdoor radar enclosures. |
| ESD-Robust Die Handling | HBM Class 1A rating with strict AuSn-only soldering protocol ensures yield integrity during automated die attach processes. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage-variable RF attenuator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| QPL9547 | 0.5–6 GHz range, 30 dB range, integrated bias tee, 3.5 mm × 2.5 mm QFN package. | Limited to sub-6 GHz; unsuitable for Ka-band or radar harmonics above 10 GHz. | Select when board space permits larger package and bandwidth needs are below 6 GHz with simplified DC biasing. |
| PE43711 | DC–6 GHz, 31.5 dB range, SPI interface, 4 × 4 mm QFN, built-in DAC and serial control. | Digital control only; no analog VC/VS interface; incompatible with analog AGC loops requiring continuous voltage sweep. | Choose for digitally controlled test equipment where firmware integration outweighs analog flexibility and bandwidth. |
Compared with QPL9547 and PE43711, the TGL2767 uniquely supports 2–25 GHz analog attenuation with die-level integration, making it irreplaceable in compact, high-frequency systems requiring direct voltage control and minimal parasitic loading-no alternative matches its combination of bandwidth, linearity, and form factor.

FAQ
What is the recommended control voltage range for the TGL2767?
The TGL2767 requires VC between 0.0 V and 1.5 V, with VS fixed at 1.5 V and VC ≤ VS. Exceeding ±3.0 V on either VC or VS risks permanent damage per absolute maximum ratings. Operation within 0–1.5 V ensures monotonic 20 dB attenuation sweep with <0.1 dB hysteresis across temperature.
Can the TGL2767 be used above 25 GHz?
No-the TGL2767 is characterized and specified only from 2–25 GHz. Performance beyond 25 GHz is not guaranteed; insertion loss rises sharply and return loss degrades above 25 GHz per datasheet S-parameter plots. For Ka-band fundamental use, consider Qorvo's TGL2220 series instead.
Is the TGL2767 supplied as a packaged IC or bare die?
The TGL2767 is supplied as a bare die (1.17 × 0.98 mm) with gold bond pads and backside ground. It is not offered in a surface-mount package. Customers must integrate it using flip-chip, epoxy mount, or wire-bond assembly onto RF substrates such as Rogers RO4003C, per Qorvo's EVB layout guidelines.
What is the thermal resistance and maximum channel temperature of the TGL2767?
The TGL2767 has a junction-to-case thermal resistance (θJC) of 40.0 °C/W when mounted to a CuMo carrier plate at 85 °C base temperature. Its maximum rated channel temperature is 125 °C. Sustained operation above this limit accelerates aging; median lifetime drops below 2.4E+7 hours per reliability data.
Does the TGL2767 require external matching components?
No-the TGL2767 is fully matched to 50 Ω at both RF input (pin 1) and RF output (pin 4), eliminating the need for external matching networks. However, AC coupling capacitors are required on both RF ports per datasheet application circuit, and proper microstrip launch design is essential to preserve broadband return loss >12 dB.
