Product details
Overview
BGY68,112 from NXP Semiconductors is a hybrid high dynamic range reverse amplifier module designed for CATV upstream signal conditioning in two-way cable systems. It operates at 24 V DC supply, delivers 30 dB typical power gain across 5–75 MHz, achieves ≤ ±0.2 dB frequency response flatness, and maintains −68 dB CTB distortion at 50 dBmV output - enabling reliable return-path amplification in headend and node applications.
For engineers reviewing the BGY68,112 datasheet, BGY68,112 pinout, BGY68,112 application, or BGY68,112 equivalent, this page provides verified specifications including RF input/output impedance (75 Ω), noise figure (3.5 dB at 75 MHz), total DC current draw (≤135 mA), and SOT115J mechanical mounting details - all critical for upstream amplifier stage design and layout validation.
Technical Context
The BGY68,112 implements a broadband hybrid amplifier architecture optimized for reverse-path (upstream) operation in 5–75 MHz CATV systems, with input and output matched to 75 Ω and common-ground RF ports. Its silicon nitride passivation and gold metallization support rugged operation under thermal cycling and humidity stress.
It features a fixed +VB supply pin (Pin 5), four common/ground terminals (Pins 2, 3, 7, 8), and dedicated RF input (Pin 1) and output (Pin 9) - configured for single-ended 75 Ω signal flow without external biasing components. The module withstands transient supply voltages up to 30 V while operating nominally at 24 V DC.

Equivalent & Alternatives
The following parts are listed as comparable options for similar reverse-path amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX2472ASA+ | 50 Ω I/O, 20–450 MHz bandwidth, 22 dB gain, 4.5 dB NF; requires external bias and matching networks | Designed for general-purpose RF gain blocks, not pre-matched for CATV 75 Ω return-path use | Use only with full impedance transformation and thermal redesign; not a direct replacement |
| QPL9057 | 75 Ω I/O, 5–1218 MHz, 20 dB gain, 3.2 dB NF; integrated active bias, no flange mount | Optimized for compact DOCSIS 4.0 modules; lacks aluminum flange for chassis-level heat sinking | Select when board space is constrained and thermal load is <1 W; verify mounting method compatibility |
Compared with MAX2472ASA+ and QPL9057, the BGY68,112 delivers higher gain (30 dB vs. ≤22 dB), superior CTB (−68 dB vs. ≥−62 dB), and integrated thermal management via SOT115J flange - making it uniquely suited for high-density, high-reliability CATV upstream amplifier cards where 75 Ω interface and field-proven longevity are mandatory.

FAQ
What is the recommended operating voltage for BGY68,112?
The BGY68,112 is specified for nominal operation at 24 V DC applied to Pin 5 (+VB). It tolerates transient supply excursions up to 30 V per IEC 60134 limiting values, but sustained operation above 24 V may reduce long-term reliability. Always use low-ESR bulk and ceramic capacitors at the +VB pin to suppress switching noise in shared power rails.
Does BGY68,112 require external bias circuitry?
No, the BGY68,112 is a fully self-biased hybrid amplifier module. All internal transistor bias points are set by on-module resistive networks and do not require external current sources, voltage dividers, or temperature compensation circuits. Only +24 V DC and proper RF grounding are needed for functional operation.
What is the thermal mounting requirement for BGY68,112?
The BGY68,112 must be mounted via its aluminum flange to a thermally conductive heatsink or chassis surface using the four 6-32 UNC mounting holes. Maximum mounting base temperature is +100 °C; operation above this limit risks permanent gain shift and increased distortion. Thermal interface material with ≤0.5 °C·in²/W resistance is recommended.
Can BGY68,112 be used in forward-path (downstream) applications?
No - the BGY68,112 is unidirectionally optimized as a reverse-path (upstream) amplifier with 5–75 MHz bandwidth and 75 Ω input/output matching. Its gain profile, return loss, and distortion characteristics are not characterized or guaranteed for downstream 54–1002 MHz operation. Use NXP's BGAxx series for downstream amplification.
Is BGY68,112 compliant with DOCSIS 4.0 upstream specifications?
Yes - the BGY68,112 meets key DOCSIS 4.0 upstream requirements: ≥30 dB gain, ≤±0.2 dB flatness over 5–75 MHz, −68 dB CTB at 50 dBmV output, and 3.5 dB noise figure at 75 MHz. Its 75 Ω I/O and thermal robustness support multi-carrier OFDMA operation in real-world node and headend deployments.
