Product details
Overview
CGD1044H,112 from NXP is a 40–1000 MHz GaAs HFET-based CATV power doubler IC designed for trunk amplifiers and line extenders in Hybrid Fiber Coax (HFC) networks. It delivers 25 dB typical power gain, −69 dBc composite triple beat (CTB), −68 dBc composite second-order (CSO), 6 dB maximum noise figure, and 450 mA typical current consumption.
For engineers reviewing the CGD1044H,112 datasheet, CGD1044H,112 pinout, CGD1044H,112 application, or CGD1044H,112 equivalent, key selection criteria include CTB/CSO distortion performance at 1 GHz, thermal vias-enabled thermal management in HVQFN packaging, and compatibility with N+0/N+1/N+2 fiber-deep optical node architectures.
Technical Context
The CGD1044H,112 employs a high-ruggedness GaAs HFET die optimized for linear RF amplification in broadband cable infrastructure. Its architecture targets low-slope (1 dB typical) response across 40–1000 MHz to maintain flat channel loading in multi-carrier CATV systems.
Integrated temperature-control circuitry stabilizes gain and distortion over industrial temperature ranges, while the HVQFN package mounts directly onto thermal vias for efficient heat transfer to external heatsinks-enabling sustained operation under high-power stress without derating.
Key Specifications

Pinout & Package
The CGD1044H,112 is housed in an HVQFN (Heat-Via Quad Flat No-lead) package with exposed thermal pad, optimized for direct thermal coupling to PCB vias and heatsinks.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD | Positive DC supply input | Accepts 24 V ±10% DC; internal regulation not provided-requires external filtering and decoupling. |
| RF IN | Input RF port | 50 Ω matched input; DC-blocked internally; requires external AC coupling for baseband-coupled sources. |
| RF OUT | Output RF port | 50 Ω matched output; capable of +60 dBmV output power into 75 Ω load per NXP reference design. |
| GND | Signal and power ground | Multiple GND pads including thermal pad; must be connected to solid ground plane via ≥6 thermal vias. |
| BIAS | Adjustable bias control | Analog voltage input (0.5–1.2 V) sets quiescent current; enables fine-tuning of linearity vs. power trade-off. |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar CATV power doubler applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CGD1044Hi,112 | Same 25 dB gain and −69 dBc CTB, but adds enhanced ESD protection (>2000 V HBM) and tighter gain tolerance (±0.5 dB). | Preferred for outdoor cabinet deployments subject to frequent lightning transients or handling during field installation. | Select CGD1044Hi,112 when ESD robustness exceeds 1500 V HBM is contractually required. |
| CGD1042H,112 | 23 dB gain (−2 dB lower), identical −69 dBc CTB/CSO, same 40–1000 MHz range and HVQFN package. | Suitable for shorter trunk spans or lower-channel-count nodes where 23 dB gain suffices and power budget is constrained. | Choose CGD1042H,112 to reduce total current draw by 10 mA while maintaining distortion compliance. |
Compared with CGD1044Hi,112, the CGD1044H,112 offers identical RF performance at lower ESD rating and cost; versus CGD1042H,112, it delivers +2 dB gain for longer reach or higher split ratios-without changing PCB layout or thermal design.

FAQ
What is the operating temperature range for the CGD1044H,112?
The CGD1044H,112 is specified for operation from −40°C to +100°C ambient, with internal temperature-control circuitry maintaining stable gain and distortion across this range. This industrial-grade thermal envelope supports deployment in unventilated outdoor cabinets and pole-mounted amplifiers where passive cooling dominates.
Does the CGD1044H,112 require external biasing components?
Yes-the CGD1044H,112 uses an analog BIAS pin (0.5–1.2 V) to set quiescent current; a precision voltage divider or DAC is required. Unlike fixed-bias alternatives, this allows real-time optimization of linearity versus power consumption in the final system, and the CGD1044H,112 datasheet provides recommended resistor values for 450 mA nominal operation.
Is the CGD1044H,112 pin-compatible with other CGD104xH variants?
Yes-the CGD1044H,112 shares identical HVQFN-16 package dimensions, pin count, pinout, and thermal pad layout with CGD1040H, CGD1042H, and CGD1044H,112 family members. This enables drop-in replacement within the same PCB footprint, though bias voltage and thermal management must be verified per variant's current and gain profile.
What is the maximum RF output power capability of the CGD1044H,112?
The CGD1044H,112 delivers +60 dBmV typical output power into a 75 Ω load at 1 GHz under standard test conditions (24 V, 450 mA, 25°C). This output level meets DOCSIS 4.0 RF interface specifications and supports up to 128-QAM modulation across 1002 MHz bandwidth without clipping or compression-induced distortion.
How does the CGD1044H,112 achieve its low 1 dB typical slope?
The CGD1044H,112 achieves 1 dB typical slope through monolithic GaAs HFET die design with integrated frequency compensation and optimized impedance matching networks across 40–1000 MHz. This eliminates the need for external passive equalizers in most trunk amplifier designs, reducing bill-of-materials cost and improving reliability compared to discrete LC-based slope correction.
