Product details
Overview
CGD1040HI,112 from NXP Semiconductors is a GaAs hybrid amplifier module in SOT115J package, designed as a high-output-power RF doubler for CATV distribution amplifiers. It delivers 20.8 dB typical power gain across 40–1003 MHz at 24 V DC supply, with −74 dBc composite triple beat (CTB) and 63 dBc carrier-to-composite noise (CCN) at 1003 MHz under 56.4 dBmV output.
For engineers reviewing the CGD1040HI,112 datasheet, CGD1040HI,112 pinout, CGD1040HI,112 application, or CGD1040HI,112 equivalent, key selection criteria include its 75 Ω impedance matching, unconditionally stable operation, integrated ring-wave surge protection, and thermal robustness for headend and node amplifier designs requiring low distortion in dense channel environments.
Technical Context
The CGD1040HI,112 employs GaAs HFET dies in a thermally optimized hybrid construction, enabling stable broadband amplification from 40 MHz to 1003 MHz with flat frequency response (≤1 dB flatness) and gain compensation over temperature. Its input/output return loss exceeds 16 dB across the full band, supporting impedance-matched cascaded stages in 75 Ω CATV infrastructure.
Operating at 24 V DC with 450 mA typical total current, the module integrates ESD protection (2000 V HBM), ring-wave surge immunity, and RoHS compliance. Its SOT115J package features an aluminum flange with vertical/horizontal mounting holes and gold-plated leads for reliable thermal dissipation and mechanical stability in outdoor or rack-mounted enclosures.

Equivalent & Alternatives
The following parts are listed as comparable options for similar RF power amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CGD1040H,112 | Same die and performance, but non-RoHS compliant (lead-based solder finish) | Restricted to legacy industrial or non-EU deployments where RoHS exemption applies | Select only if RoHS compliance is not required and legacy inventory reuse is prioritized |
| CGD1035HI,112 | Lower gain (18 dB typ.), narrower bandwidth (45–870 MHz), reduced CTB (−68 dBc) | Better suited for mid-split or legacy analog-only CATV nodes with lower channel count | Choose when thermal budget or cost constraints outweigh need for full 1003 MHz support and highest linearity |
Compared with CGD1040HI,112, the CGD1040H,112 offers identical RF performance but lacks RoHS compliance, while CGD1035HI,112 trades bandwidth and distortion performance for lower power consumption and cost-making it suitable for less demanding analog-dominant deployments.

FAQ
What is the maximum supply voltage rating for CGD1040HI,112?
The absolute maximum supply voltage for CGD1040HI,112 is 30 V DC, per IEC 60134 limiting values. Operation above 24 V DC increases power dissipation and may reduce thermal margin; sustained use at 30 V is not recommended without derating current and verifying mounting base temperature remains ≤100 °C. The CGD1040HI,112 is characterized and specified at 24 V DC for optimal linearity and reliability.
Does CGD1040HI,112 require external bias sequencing or startup circuitry?
No, CGD1040HI,112 operates with a single 24 V DC supply applied directly to pin 5 (+VB) and does not require bias sequencing, enable pins, or external startup circuitry. Its internal HFET bias network is self-stabilizing and unconditionally stable across temperature and load variations. The CGD1040HI,112 achieves full RF performance within microseconds of power application.
Can CGD1040HI,112 be used in 50 Ω systems?
CGD1040HI,112 is optimized for 75 Ω CATV systems and exhibits degraded return loss (<10 dB) and increased distortion when operated into 50 Ω loads. Its input/output matching networks are fixed for 75 Ω; using it in 50 Ω applications requires external matching networks that compromise bandwidth, flatness, and CTB performance. For 50 Ω systems, consider NXP's MGA-31389 or similar 50 Ω RF amplifiers instead of CGD1040HI,112.
What is the thermal resistance from junction to case for CGD1040HI,112?
The CGD1040HI,112 does not specify junction-to-case thermal resistance in its datasheet, but its SOT115J package uses a direct-mount aluminum flange design. With proper thermal interface material and mounting torque (5–7 in·lb), measured junction-to-heatsink resistance is ≤1.5 °C/W. Mounting base temperature (Tmb) must be maintained ≤100 °C; the CGD1040HI,112's thermal design assumes heatsink attachment to the flange, not PCB conduction.
Is CGD1040HI,112 qualified for outdoor cabinet deployment?
Yes, CGD1040HI,112 is qualified for outdoor cabinet use due to its −20 °C to +100 °C mounting base temperature rating, integrated ring-wave surge protection (IEC 61000-4-5), and 2000 V HBM ESD tolerance. Its SOT115J package includes corrosion-resistant gold-plated leads and aluminum flange compatible with conformal coating. When installed per NXP's mounting guidelines, the CGD1040HI,112 meets Telcordia GR-1089-CORE for electromagnetic immunity in outdoor telecom environments.
