Product details
Overview
BGD702N from NXP Semiconductors is a hybrid RF power doubler amplifier module designed for CATV distribution systems, delivering 18.5 dB small-signal gain at 750 MHz, operating from a 24 V DC supply, with total current consumption ≤435 mA and output voltage up to 64.5 dBmV across 40–750 MHz bandwidth.
For engineers reviewing the BGD702N datasheet, BGD702N pinout, BGD702N application, or BGD702N equivalent, this device is selected for high-linearity, low-noise broadband amplification in cable TV headend and node applications where composite distortion (CTB ≤ –67 dB), flat frequency response (±0.25 dB), and rugged 75 Ω impedance matching are critical.
Technical Context
The BGD702N implements a silicon-based hybrid amplifier architecture with gold metallization and silicon nitride passivation, optimized for 75 Ω CATV signal paths. It supports dual-tone intermodulation testing per DIN45004B and delivers stable gain across 40–750 MHz with input/output return loss ≥16 dB up to 750 MHz.
Its design targets multi-channel flatness under high-output conditions: CTB reaches –67 dB with 77 channels, CSO –62 dB, and Xmod –67 dB at 44 dBmV output level-enabled by low noise figure (5.5–8.5 dB) and excellent linearity over temperature (Tmb = –20 to +100 °C).

Applications
| CATV Trunk Amplifier Stage | CATV Node Amplifier |
|---|---|
Use Scenario: Signal boosting between headend and distribution hubs over coaxial trunk lines spanning >1 km. IC Role / Device Role / Timing Role: Power doubler amplifier providing gain compensation and distortion management in cascaded analog/digital channel stacks. Use Value: Enables 750 MHz bandwidth support with ±0.25 dB flatness and CTB < –65 dB - critical for maintaining signal integrity across 110-channel DOCSIS deployments. |
Use Scenario: Active signal regeneration at fiber-to-coax nodes serving 500–2000 homes passed. IC Role / Device Role / Timing Role: Final-stage broadband amplifier driving drop cables with minimal added noise and distortion. Use Value: Delivers 64.5 dBmV output at 44 dBmV input while sustaining F = 6.5 dB NF at 450–550 MHz - preserves upstream SNR for DOCSIS 3.1 upstream channels. |
| CATV Optical Receiver Output Stage | Two-Way Splitter Amplifier Module |
Use Scenario: Post-photodiode amplification in optical receivers converting 1550 nm RF-over-fiber signals to 75 Ω coax outputs.

Use Scenario: Bidirectional amplification in active splitters handling both downstream broadcast and upstream burst transmissions. IC Role / Device Role / Timing Role: Dual-path RF amplifier supporting simultaneous 5–65 MHz upstream and 54–750 MHz downstream bands. Use Value: Input/output return loss ≥16 dB across full band - reduces reflections that cause echo and ingress in two-way HFC networks. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar RF power doubler amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX2108ETL+ | Monolithic SiGe IC; 5 V supply; 40–1000 MHz; gain = 17.5 dB; NF = 4.2 dB; no flange package | Designed for compact indoor set-top box front-ends, not outdoor cabinet use | Choose for space-constrained, low-power, indoor applications requiring higher integration and lower NF |
| AD8352ACPZ-R7 | Differential RF amplifier; 3.3 V supply; 10–2500 MHz; gain = 20 dB; requires external baluns and biasing | Targets wideband test equipment and software-defined radio, not 75 Ω CATV infrastructure | Choose for lab-grade instrumentation or broadband receiver designs needing differential I/O and wider bandwidth |
Compared with MAX2108ETL+ and AD8352ACPZ-R7, the BGD702N offers superior ruggedness, 75 Ω native impedance, integrated flange cooling, and proven CATV distortion performance-but requires 24 V supply and larger SOT115J footprint.

FAQ
What is the maximum operating temperature for the BGD702N?
The BGD702N has a specified operating mounting base temperature (Tmb) range of –20 °C to +100 °C. This rating reflects its thermal design for direct flange-mounting in ventilated or forced-air-cooled CATV cabinets. Operation beyond +100 °C risks permanent degradation of silicon nitride passivation and gold metallization integrity. The BGD702N must be mounted to a heatsink or chassis with low thermal resistance to maintain safe junction temperatures under full 435 mA load.
Does the BGD702N require external biasing components?
No, the BGD702N is a fully self-biased hybrid module requiring only a 24 V DC supply on pin 5 and proper RF grounding via pins 2, 3, 7, and 8. It contains internal bias networks, DC blocking capacitors, and impedance-matching elements optimized for 75 Ω systems. No external inductors, resistors, or capacitors are needed for basic operation-only input/output DC blocks and optional surge protection diodes for field deployment.
Can the BGD702N be used in DOCSIS 4.0 systems?
The BGD702N supports frequencies up to 750 MHz and meets key linearity metrics (CTB ≤ –67 dB, CSO ≤ –62 dB) required for DOCSIS 3.1 downstream operation, but it does not cover the extended 1.2 GHz or 1.8 GHz bands defined in DOCSIS 4.0. Its 40–750 MHz bandwidth and 75 Ω interface remain fully compatible with legacy and DOCSIS 3.1 infrastructure; however, upgrading to DOCSIS 4.0 full-duplex operation requires wider-bandwidth amplifiers beyond the BGD702N's specification.
What is the meaning of "power doubler" in the BGD702N's description?
"Power doubler" refers to the BGD702N's ability to deliver approximately double the RF output power relative to conventional single-stage amplifiers of similar technology-achieved through optimized hybrid circuit topology, high-efficiency transistor biasing, and flange-mounted thermal management. It does not imply frequency doubling; the device operates linearly within 40–750 MHz with no intentional harmonic generation. The term reflects legacy CATV industry nomenclature for high-output, high-linearity broadband amplifiers.
Is the BGD702N RoHS compliant?
The BGD702N was originally released in 2001, predating RoHS Directive 2002/95/EC. While NXP's later revisions of similar SOT115J-packaged devices (e.g., BGAxx series) include RoHS-compliant variants, the BGD702N itself is not certified RoHS-compliant. Customers requiring RoHS compliance should verify material declarations with NXP or consider modern alternatives such as the NXP BGU7005 or equivalents with documented lead-free finish and exemption status.
