Product details
Overview
TGL2767-SM from Qorvo is a GaAs pHEMT-based voltage-variable RF attenuator operating from 2–31 GHz, delivering 19 dB attenuation range with <2 dB insertion loss in the reference state, fully matched to 50 Ω, and designed for radar, satellite comms, and electronic warfare front-end signal conditioning.
For engineers reviewing the TGL2767-SM datasheet, pinout, applications, or equivalent options, this page provides verified electrical specs, package dimensions, thermal resistance (θJC = 40.0 °C/W), control voltage range (0–1.5 V), and IIP3 performance across frequency and attenuation states.
Technical Context
The TGL2767-SM uses Qorvo's QPHT15 0.15 µm GaAs pHEMT process to achieve broadband 2–31 GHz operation with monotonic attenuation control via analog VC (0–1.5 V) referenced to VS = 1.5 V. Its air-cavity laminate package enables stable RF performance up to Ka-band.
It features fully integrated 50 Ω input/output matching, AC-coupled RF ports, and temperature-stable attenuation response (±0.5 dB over –40 to +85 °C at fixed VC). The device supports high linearity with IIP3 >38 dBm at 0 dB attenuation and >22 dBm at 10–15 dB attenuation across 2–26 GHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Frequency Range | 2–31 GHz: Enables single-component coverage of S-, C-, X-, Ku-, K-, and lower Ka-band systems. |
| Attenuation Range | 19 dB typical (17.5 dB min at 2–25 GHz): Supports precise gain/level control in wideband transceivers. |
| Insertion Loss (Ref. State) | <2 dB max (1.6 dB typ at 2–25 GHz): Minimizes signal path degradation in low-noise receive chains. |
| Control Voltage Range | 0.0–1.5 V (VC ≤ VS): Compatible with standard DAC outputs and low-voltage analog control circuitry. |
| IIP3 (0 dB Attenuation) | >38 dBm at 25 °C, 10 MHz tone spacing: Maintains high dynamic range in receiver front-ends under strong interferers. |
| Thermal Resistance θJC | 40.0 °C/W: Enables reliable 1 W power dissipation with moderate heatsinking in compact RF modules. |
| Package Dimensions | 3.00 × 3.00 × 1.64 mm: Surface-mount compatible with high-density RF PCB layouts and automated assembly. |
Pinout & Package
3 × 3 mm air-cavity laminate package with gold-plated ENEPIG contact finish, backside thermal slug (Pin 15), and RoHS-compliant epoxy seal. MSL Level 3, reflow-compatible per J-STD-020 (260 °C peak).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 8, 10 | GND | RF ground connections; must be low-inductance vias to internal ground plane for impedance stability. |
| 2 | RF Input | 50 Ω AC-coupled input port; requires external DC blocking if source is DC-biased. |
| 4, 5, 11–14 | NC | No-connect pins; grounding recommended to reduce parasitic coupling and improve return loss. |
| 6 | VC | Analog control voltage input (0–1.5 V); low-impedance drive required to avoid attenuation nonlinearity. |
| 7 | VS | Reference voltage input (1.5 V nominal); adjusts for FET threshold variation across lots. |
| 9 | RF Output | 50 Ω AC-coupled output port; maintains broadband match independent of attenuation setting. |
| 15 (Slug) | GND | Backside thermal paddle; requires ≥6 vias to PCB ground for thermal and RF performance. |
Key Features

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 |
|---|---|---|---|
| QPL9057 | 2–6 GHz range, 30 dB attenuation, 0.5–3.3 V control, 1.5 dB IL; smaller 2 × 2 mm QFN. | Limited to sub-6 GHz; not suitable for Ka-band radar or SATCOM uplinks. | Select when bandwidth requirement is ≤6 GHz and higher attenuation range is prioritized over frequency coverage. |
| HMC650LP3E | 0.1–20 GHz, 25 dB range, 0–15 V control, 3.5 dB IL; requires external biasing and matching. | Wider low-end coverage but higher insertion loss and complex bias network needed. | Choose for legacy designs needing ultra-wide LF extension, accepting larger footprint and layout overhead. |
Compared with QPL9057 and HMC650LP3E, the TGL2767-SM uniquely delivers full 2–31 GHz coverage with <2 dB insertion loss and monolithic 50 Ω matching-enabling simplified Ka-band system integration without band-splitting or external tuning.

FAQ
What is the maximum RF input power rating for the TGL2767-SM?
The TGL2767-SM has an absolute maximum input power rating of 30 dBm (1 W), with recommended operation below this limit to maintain linearity and reliability. At 25 °C and VC = 1.5 V, it sustains >38 dBm IIP3; derating is advised above +85 °C ambient or under pulsed conditions exceeding 10% duty cycle. The TGL2767-SM thermal resistance (θJC = 40.0 °C/W) supports safe 1 W dissipation with proper PCB thermal design.
Does the TGL2767-SM require external matching components?
No, the TGL2767-SM is fully matched to 50 Ω at both RF input (Pin 2) and RF output (Pin 9), eliminating the need for external matching networks across its 2–31 GHz operating band. Its internal matching ensures consistent S11 and S22 >12 dB across temperature and attenuation settings. However, AC coupling capacitors must be placed externally on both RF ports per the evaluation board layout guidance in the datasheet.
What is the role of the VS pin on the TGL2767-SM?
The VS pin (Pin 7) supplies a 1.5 V reference voltage that sets the upper bound for VC and compensates for GaAs FET threshold variations across wafer lots. VS must be ≥ VC and stable within ±2% for accurate attenuation calibration. It is not a power supply but a precision reference; decoupling with a 100 nF capacitor near Pin 7 is required to suppress noise-induced attenuation drift in the TGL2767-SM.
Can the TGL2767-SM operate beyond 31 GHz?
No-the TGL2767-SM is characterized and specified only up to 31 GHz, with guaranteed 16 dB minimum attenuation and <3.8 dB insertion loss at 30–31 GHz. Performance degrades rapidly above 31 GHz due to parasitic limits of the 3 × 3 mm air-cavity laminate package and GaAs pHEMT intrinsic response. For operation above 31 GHz, Qorvo recommends evaluating the TGL2227 (DC–44 GHz) or custom MMIC solutions-not the TGL2767-SM.
Is the TGL2767-SM pin-compatible with other Qorvo attenuators?
No-the TGL2767-SM has a unique 15-pin configuration (including backside thermal slug) optimized for its air-cavity package and Ka-band performance; it is not pin-compatible with QPL9057 (12-pin QFN), HMC650LP3E (16-pin LP3), or earlier TGL22xx series. Layout reuse requires full redesign per the mechanical drawing in Rev G datasheet. The TGL2767-SM land pattern and via placement are specific to its thermal and RF requirements.
