Product details
Overview
ACT88321VU112SR from Qorvo is a 75Ω broadband CATV amplifier IC using GaAs pHEMT technology in Darlington configuration, delivering 12dB gain at 1800MHz, +40dBm OIP3, +24dBm P1dB, and operating from 50–1800MHz for DOCSIS 4.0 systems in cable node line driver applications.
For engineers reviewing the ACT88321VU112SR datasheet, pinout, applications, or equivalent options, key selection criteria include push-pull linearity performance, SOIC-8 thermal design requirements, 7V single-supply operation, and 75Ω impedance matching for CATV signal distribution networks.
Technical Context
The ACT88321VU112SR integrates two matched amplifiers in push-pull topology to suppress even-order distortion, enabling high MER (>42dB) across 54–1794MHz with OFDM+QAM channel loading. Its on-chip active bias circuit maintains stable IDD (150–215mA) over temperature (−40°C to +85°C).
Designed for 75Ω CATV infrastructure, it features differential RF inputs (RFIN1/RFIN2) and outputs (RFOUT1/RFOUT2), with exposed paddle GND for RF grounding and thermal dissipation. Pin 9 is the thermal pad, not a signal terminal, and requires soldered via connection to PCB ground plane.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Frequency Range | 50–1800 MHz - fully supports DOCSIS 4.0 upstream/downstream spectrum allocation. |
| Small-Signal Gain | 12 dB @ 1800 MHz - enables single-stage amplification without cascading in node line drivers. |
| OIP3 | +40 dBm @ 50/1200 MHz - ensures low composite distortion in dense multi-carrier QAM environments. |
| P1dB | +24 dBm - delivers headroom for high-output composite power (up to +62 dBmV) in 75Ω systems. |
| Noise Figure | 3.5 dB @ 1200 MHz - preserves signal integrity in cascade-sensitive trunk and distribution amplifiers. |
| Supply Voltage | 7 V (typical), 6.5–7.5 V range - compatible with standard CATV power feeding architecture. |
| Thermal Resistance | 32 °C/W - mandates thermal vias under exposed paddle for reliable operation at full load. |
Pinout & Package
Package: SOIC-8 with exposed thermal pad (Pin 9). Requires soldered thermal vias to inner/outer ground planes per Qorvo recommended mounting pattern.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (RFIN1) | RF input, plus side | Differential input terminal for balanced signal path; must be impedance-matched to 75Ω. |
| 2,3 (NC) | No connect | Internally unconnected; no external routing required. |
| 4 (RFIN2) | RF input, minus side | Complementary differential input; paired with Pin 1 for common-mode rejection. |
| 5 (RFOUT2) | RF output, minus side | Differential output terminal; used with Pin 8 for push-pull signal delivery. |
| 6,7 (NC) | No connect | Internally unconnected; leave floating or grounded per layout best practice. |
| 8 (RFOUT1) | RF output, plus side | Primary differential output; forms push-pull pair with Pin 5 to cancel even-order harmonics. |
| 9 (GND) | Exposed thermal pad | DC and RF ground reference; must be soldered with ≥4 thermal vias (0.25 mm plated) to internal ground plane. |
Key Features
| Feature | Design Value |
|---|---|
| Darlington pHEMT architecture | Enables broadband 50–1800 MHz operation with stable gain slope ≤1.0 dB across band. |
| On-chip active bias | Maintains consistent 215 mA supply current across −40°C to +85°C, eliminating external bias network. |
| Push-pull dual amplifier core | Delivers >65 dB OIP2 and >40 dBm OIP3 by inherently suppressing second-harmonic distortion. |
| 75Ω system optimization | Input/output return loss ≥18 dB across full band - minimizes reflections in coaxial CATV plant. |
| RoHS-compliant lead-free packaging | Compatible with 260°C reflow profiles; NiPdAu contact plating ensures long-term solder joint reliability. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar broadband CATV amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| QPL1815SR | Identical die, same SOIC-8 package, identical electrical specs - only differs in reel packaging (100-piece vs 112-piece). | Same functional use in CATV nodes and line drivers; no design change required. | Select QPL1815SR when standard 100-piece reel logistics align with production planning. |
| QPL1814TR13 | Lower OIP3 (+37 dBm typ), narrower bandwidth (45–1218 MHz), same 7V supply and SOIC-8 package. | Suitable for legacy DOCSIS 3.1 nodes but lacks full 1800 MHz support for DOCSIS 4.0 upstream expansion. | Choose QPL1814TR13 only for cost-sensitive DOCSIS 3.1 upgrades where 1218 MHz upper limit is acceptable. |
Compared with QPL1815SR, ACT88321VU112SR offers identical RF performance but ships in a non-standard 112-piece reel - advantageous for prototyping or small-batch validation. Against QPL1814TR13, ACT88321VU112SR provides critical 1800 MHz bandwidth and +3 dB higher OIP3 needed for DOCSIS 4.0 spectral efficiency.

FAQ
What is the absolute maximum supply voltage for ACT88321VU112SR?
The absolute maximum supply voltage for ACT88321VU112SR is 9 V. Operation above this rating risks permanent damage. The device is specified for typical operation at 7 V (6.5–7.5 V range), and exceeding 9 V violates Absolute Maximum Ratings per Qorvo's datasheet Rev E. Always use regulated 7 V supplies with appropriate decoupling for reliable ACT88321VU112SR performance.
Does ACT88321VU112SR require external bias components?
No, ACT88321VU112SR does not require external bias components. It integrates an on-chip active bias circuit that maintains stable quiescent current (215 mA typ) across temperature and process variation. This eliminates the need for external resistors or regulators, simplifying layout and improving repeatability in ACT88321VU112SR-based designs.
How is thermal management implemented for ACT88321VU112SR?
ACT88321VU112SR uses an exposed thermal pad (Pin 9) requiring direct solder connection to the PCB ground plane with ≥4 thermal vias (0.25 mm plated diameter). Thermal resistance is 32 °C/W; failure to implement vias results in junction temperature exceeding +165 °C. Proper thermal design is mandatory for sustained +24 dBm P1dB operation of ACT88321VU112SR.
Is ACT88321VU112SR compatible with lead-free reflow processes?
Yes, ACT88321VU112SR is fully compatible with lead-free reflow processes, rated for peak temperatures up to 260 °C. Its NiPdAu contact plating ensures robust solderability and intermetallic formation control. Standard JEDEC J-STD-020 MSL 3 handling applies, and moisture bake-out is required if floor life is exceeded before ACT88321VU112SR assembly.
What is the role of Pins 2, 3, 6, and 7 on ACT88321VU112SR?
Pins 2, 3, 6, and 7 on ACT88321VU112SR are No Connect (NC) terminals - internally unconnected and electrically isolated. They must not be routed or tied to any net. Leaving them floating is acceptable; grounding is optional but unnecessary. These pins exist for mechanical symmetry and package compatibility, not functional use in ACT88321VU112SR circuits.
