Product details
Overview
D10040250GT from RF Micro Devices is a GaAs-based Hybrid Power Doubler amplifier module designed for CATV distribution systems. It operates from 40MHz to 1000MHz, delivers ≥24.5dB gain at 1GHz, achieves ≤5.5dB noise figure, and supports 75Ω impedance matching with unconditionally stable operation under all terminations.
For engineers reviewing the D10040250GT datasheet, pinout, applications, or equivalent options, key selection criteria include its 375mA max DC current at 24V, CTB/XMOD/CSO distortion performance (–64dBc/–60dBc/–65dBc), flatness ≤0.8dB across 40–1000MHz, and SOT-115J package compatibility with CATV line extender and node amplifier designs.
Technical Context
The D10040250GT implements a two-stage GaAs MMIC hybrid architecture with internal biasing and impedance-matched I/O ports. Its frequency response is optimized for broadband CATV signal amplification, maintaining ≥16dB input/output return loss across 40–1000MHz and slope ≤2.0dB over that band.
It operates at fixed 24VDC supply with 350–375mA consumption, requires no external bias network, and is unconditionally stable without external stabilization components - enabling direct integration into 75Ω coaxial signal paths in headend, hub, and fiber-node applications.

Equivalent & Alternatives
The following parts are listed as comparable options for similar CATV power doubler amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Qorvo QPA3232 | Higher gain (27dB), wider bandwidth (45–1218MHz), but higher current (420mA) and larger SOT-115J variant | Supports DOCSIS 4.0 extended spectrum; requires revised thermal management | Preferred when extending beyond 1GHz or requiring higher cascade margin |
| Skyworks SKY65167-360LF | Lower gain (22dB), narrower band (45–1003MHz), lower current (320mA), same SOT-115J footprint | Optimized for cost-sensitive node upgrades; reduced distortion spec (–60dBc CTB) | Valid alternative where legacy 132-ch NTSC performance suffices and power budget is constrained |
Compared with QPA3232 and SKY65167-360LF, the D10040250GT offers the best balance of gain flatness (0.8dB), distortion (–64dBc CTB), and thermal robustness (100°C base temp) within strict 24V/375mA constraints for field-deployed CATV infrastructure.

FAQ
What is the operating voltage range for the D10040250GT?
The D10040250GT is designed for single-supply operation at 24VDC nominal, with absolute maximum rating of 30V for up to 5 minutes. Its internal bias network regulates operation across this range, and typical current draw is 350–375mA. The D10040250GT does not support variable or dual-voltage operation - deviation from 24VDC will degrade gain flatness and distortion performance per DS131219 specifications.
Is the D10040250GT pin-compatible with other SOT-115J CATV amplifiers?
The D10040250GT uses a defined 9-pin SOT-115J pinout with specific NC assignments (pins 4 and 6) and dual ground groups (pins 2–3 and 7–8). While physical footprint matches standard SOT-115J, pin functions differ from Qorvo QPA3232 and Skyworks SKY65167-360LF - direct replacement requires verification of pin mapping and biasing. The D10040250GT must be evaluated individually for PCB layout compatibility.
Does the D10040250GT require external matching components?
No, the D10040250GT integrates fully matched 75Ω input and output ports across 40–1000MHz, eliminating the need for external baluns, transformers, or tuning stubs. Its S-parameter data confirms ≥16dB return loss without external networks. The D10040250GT is qualified for direct connection to coaxial traces and connectors in CATV hardware, provided proper grounding and thermal pad layout per DS131219 mechanical drawing.
What is the thermal derating behavior of the D10040250GT above 30°C mounting base temperature?
The D10040250GT specifies operating mounting base temperature from –30°C to +100°C, with nominal performance (gain, distortion, NF) characterized at 30°C. Above 30°C, gain decreases by ~0.02dB/°C and distortion degrades ~0.1dBc/°C based on thermal coefficient data in DS131219. The D10040250GT maintains functional operation up to +100°C, but system-level CNR and CTB margins must be re-evaluated at elevated temperatures.
How is the D10040250GT protected against ESD damage during handling?
The D10040250GT is classified as ESD-sensitive per JEDEC JS-001 Class 1B (≥250V HBM). It features internal protection diodes on RF and supply pins, but requires strict handling per RFMD's ESD control guidelines: grounded wrist straps, dissipative mats, and ionized air environments. The D10040250GT's SOT-115J package includes conductive baseplate grounding, and improper handling may permanently degrade return loss or increase noise figure without visible damage.
