Product details
Overview
CGD982HCI from NXP Semiconductors is a GaAs-based hybrid amplifier module in SOT115J package, designed as a high-output-power RF doubler for CATV distribution amplifiers. It delivers 23 dB typical power gain at 1003 MHz, −66 dBc composite triple beat (CTB) distortion at 862 MHz with 48 dBmV output, and draws 450 mA total current at 24 V DC supply - enabling flat frequency response up to 1003 MHz in PAL D/NTSC broadband systems.
For engineers reviewing the CGD982HCI datasheet, CGD982HCI pinout, CGD982HCI application, or CGD982HCI equivalent, this device is selected for demanding CATV line extender, node amplifier, and optical receiver output stage designs requiring stable 75 Ω impedance matching, ESD-hardened operation, and thermal robustness across −20 °C to +100 °C mounting base temperature.
Technical Context
The CGD982HCI integrates two GaAs HFET dies in a thermally optimized hybrid configuration, operating as a direct-coupled RF doubler with unconditionally stable gain across 40–1003 MHz. Its input and output return loss exceeds 16 dB over full bandwidth, and it features integrated ring wave surge protection compliant with IEC61000-4-2 (1500 V).
Gain flatness is maintained within ±1 dB (peak deviation), slope straight-line deviation is ≤2 dB, and temperature-compensated bias ensures consistent performance under varying thermal load. The module uses gold-plated in-line leads and an aluminum flange for efficient heat dissipation at mounting base temperatures up to +100 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Power Gain | 23 dB typ. at 1003 MHz - enables single-stage amplification without cascading in 1 GHz CATV nodes |
| Bandwidth | 40 MHz to 1003 MHz - supports full PAL D (47–862 MHz), NTSC (45–750 MHz), and digital channel (550–1003 MHz) loading |
| CTB Distortion | −66 dBc typ. at 862 MHz (48 dBmV output) - meets stringent multi-channel analog/digital coexistence requirements |
| Total Current | 450 mA typ. at 24 V DC - defines thermal design margin and heatsink sizing for continuous operation |
| Input/Output Return Loss | ≥16 dB from 870–1003 MHz - ensures minimal signal reflection in 75 Ω coaxial distribution networks |
| Noise Figure | 5.5 dB typ. at 1003 MHz - preserves carrier-to-noise ratio in cascade-sensitive optical receiver outputs |
| ESD Rating | 2000 V HBM / 1500 V IEC61000-4-2 - allows safe handling and field deployment in non-ESD-controlled environments |
Pinout & Package
SOT115J is a rectangular single-ended hybrid package with aluminum flange, 2 vertical and 2 horizontal 6-32 UNC mounting holes, and 7 gold-plated in-line leads. Thermal path is optimized via flange-to-heatsink conduction; mechanical outline conforms to IEC/JEDEC standards with 38.1 mm × 25.4 mm footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| 2, 3 | Common Ground | RF and DC ground reference; must be low-inductance connection to system ground plane |
| 5 | +VB Supply | 24 V DC power input; requires local 10 µF/0.1 µF decoupling near pin |
| 7, 8 | Common Ground | Secondary ground path; ties to flange for thermal and RF grounding |
| 9 | RF Output | 75 Ω matched output port; capable of driving 48 dBmV into 75 Ω load continuously |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar RF power doubler applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CGD983HCI | 24 dB gain at 1003 MHz; 470 mA typical current; identical SOT115J package and pinout | Higher gain enables lower cascade noise figure but increases distortion sensitivity at max output | Select when system requires ≥24 dB gain and can accommodate tighter CTB budget (−64 dBc typ.) |
| CGD981HCI | 20 dB gain at 1003 MHz; 420 mA typical current; same SOT115J package and pinout | Lower gain reduces distortion and thermal load, suited for shorter trunk runs or lower channel counts | Select when flatness priority outweighs gain, or when operating below 862 MHz with relaxed CTB requirements |
Compared with CGD982HCI, CGD983HCI offers higher gain at marginally increased distortion, while CGD981HCI trades 3 dB gain for improved thermal headroom and lower distortion - enabling precise optimization for specific node length, channel loading, and thermal envelope constraints.

FAQ
What is the maximum supply voltage for CGD982HCI?
The absolute maximum supply voltage for CGD982HCI is 30 V DC, per IEC 60134 limiting values. Operation at 24 V DC is recommended for optimal linearity and thermal performance; exceeding 24 V increases current draw and distortion without proportional gain improvement. The CGD982HCI must be protected from transients above 30 V to prevent permanent damage.
Does CGD982HCI require external biasing components?
No, CGD982HCI is a fully self-biased hybrid module with internal temperature-compensated bias network. It requires only a 24 V DC supply applied to pin 5 (+VB), local decoupling (10 µF + 0.1 µF), and proper RF grounding via pins 2, 3, 7, and 8. No external resistors, capacitors, or inductors are needed for basic operation of the CGD982HCI.
What is the meaning of "flat Vo till 862 MHz" in CGD982HCI documentation?
"Flat Vo till 862 MHz" means the CGD982HCI maintains output voltage amplitude variation within ±0.5 dB across 47–862 MHz under PAL D loading conditions (98 channels, 8 MHz each). This flatness is achieved via internal gain compensation and is verified at 48 dBmV output level - confirming suitability for legacy CATV systems without external equalization.
Can CGD982HCI drive a 75 Ω load directly without matching networks?
Yes, CGD982HCI is internally matched to 75 Ω at both input and output across its full 40–1003 MHz bandwidth. Its input and output return loss exceeds 16 dB at 1003 MHz, allowing direct connection to standard CATV coaxial infrastructure. No external matching components are required for nominal 75 Ω system integration of the CGD982HCI.
Is CGD982HCI qualified for outdoor cabinet use?
Yes, CGD982HCI supports mounting base temperatures from −20 °C to +100 °C and features an aluminum flange for direct heatsink attachment. Its rugged construction, integrated surge protection, and 2000 V HBM ESD rating make it suitable for sealed outdoor cabinets in cable plant environments - provided ambient temperature and airflow meet derating guidelines for the CGD982HCI.
