Product details
Overview
CGD982HC from NXP Semiconductors is a GaAs-based hybrid amplifier module in SOT115J package, designed as a high-output-power RF doubler for CATV distribution systems. It delivers 22–24 dB gain across 40–1003 MHz at 24 V DC supply, achieves −66 dBc typical CTB distortion at 862 MHz with 48 dBmV output, and maintains ≤1 dB flatness over full bandwidth - enabling multi-channel PAL D/NTSC signal amplification in headend and node applications.
For engineers reviewing the CGD982HC datasheet, CGD982HC pinout, CGD982HC application, or CGD982HC equivalent, this page provides verified specifications including power gain vs. frequency, composite distortion performance under 98-PAL-D and 112-NTSC loading, input/output return loss down to 16 dB at 1 GHz, thermal stability up to 100 °C mounting base temperature, and RoHS-compliant rugged construction for field-deployable CATV infrastructure.
Technical Context
The CGD982HC integrates two GaAs HFET dies in a thermally optimized, unconditionally stable doubler configuration. Its gain compensation over temperature ensures consistent RF output level across −20 °C to +100 °C mounting base range, while its 75 Ω input/output impedance matches standard CATV system architecture without external matching networks.
Designed for flat frequency response (≤1 dB deviation), the module supports simultaneous amplification of analog PAL D (47–862 MHz) and digital (550–1003 MHz) channels. Its 440–460 mA total current draw at 24 V enables efficient operation in cascaded amplifier stages where power budget and thermal management are critical.

Equivalent & Alternatives
The following parts are listed as comparable options for similar RF power doubler applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CGD983HC | Same SOT115J package; 23–25 dB gain at 1003 MHz; higher 480–500 mA current draw; identical distortion specs | Better suited for ultra-high-channel-count (>120) digital deployments requiring marginally higher gain | Select CGD983HC only when ≥23.5 dB gain at 1 GHz is required and thermal headroom allows +20 mA extra current |
| CGD981HC | Lower 20–22 dB gain at 1003 MHz; 420–440 mA current; same 40–1003 MHz bandwidth and RoHS compliance | Targeted at lower-power nodes or shorter trunk segments where gain margin is less critical | Choose CGD981HC for cost-sensitive or thermally constrained installations where 22 dB gain suffices |
Compared with CGD982HC, CGD983HC offers +1 dB gain at 1 GHz but increases thermal load by ~20 mA, while CGD981HC reduces current draw by ~20 mA at the expense of 1 dB gain - making CGD982HC the balanced choice for standard 98-PAL-D/112-NTSC deployments requiring optimal linearity-to-power ratio.

FAQ
What is the maximum operating temperature for the CGD982HC mounting base?
The CGD982HC is rated for mounting base temperatures from −20 °C to +100 °C per IEC 60134 limiting values. Operation above +100 °C risks permanent degradation of GaAs die performance and bond wire integrity. For continuous operation in outdoor cabinets, derating is recommended above 85 °C ambient with adequate heatsinking. The CGD982HC thermal design supports stable gain and distortion performance across this full range without external thermal compensation.
Does the CGD982HC require external biasing or matching components?
No, the CGD982HC is a fully self-contained hybrid amplifier module with integrated DC biasing and 75 Ω input/output impedance matching. It operates directly from 24 V DC with no external RF chokes, blocking capacitors, or matching networks required. The SOT115J package incorporates internal bypassing and thermal stabilization, enabling plug-and-play integration into standard CATV amplifier layouts. This simplifies design and improves reliability compared to discrete GaAs FET implementations.
How does the CGD982HC perform under 79 NTSC + 75 digital channel loading?
Under 79 NTSC + 75 digital channel loading (54–1003 MHz, −6 dB offset), the CGD982HC delivers −75 dBc typical CTB and −77 dBc typical CSO at 56.4 dBmV output at 1003 MHz, with carrier-to-composite noise (CCN) of 57 dBc. These values exceed industry requirements for high-density digital cable systems and confirm its suitability for mixed analog/digital network upgrades. The CGD982HC maintains this performance without tilt correction due to its ≤1 dB flatness specification across the full band.
Is the CGD982HC pin-compatible with earlier NXP CATV amplifier modules?
The CGD982HC uses the SOT115J package with 7 gold-plated in-line leads and specific pin assignments (input on pin 1, output on pin 9, +VB on pin 5). It is not pin-compatible with older SOT115J variants like CGD980HC or CGD981HC due to differences in internal biasing topology and thermal pad configuration - though mechanical footprint and mounting hole pattern are identical. PCB redesign is required for drop-in replacement; however, system-level electrical interface (75 Ω, 24 V DC) remains unchanged.
What RoHS compliance level does the CGD982HC meet?
The CGD982HC complies fully with EU Directive 2002/95/EC (RoHS 1) and subsequent amendments, containing no lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls (PBB), or polybrominated diphenyl ethers (PBDE). All solderable surfaces use lead-free gold plating, and internal die attach materials are halogen-free. This compliance is certified per NXP's material declarations and verified through third-party lab testing per IEC 62321 standards. The CGD982HC is suitable for global CATV equipment markets with strict environmental regulations.
