QPC7336SR

Overview

The QPC7336SR is a voltage-controlled variable equalizer from Qorvo, optimized for DOCSIS 3.1 operations within the 45 MHz to 1218 MHz frequency range. It employs an SOI attenuator technology and operates on a 5V supply with a typical current of 2 mA. The device features a 75-ohm impedance and provides up to 22 dB of attenuation. Designed for surface-mount installation in MCM-14 packages, it supports operating temperatures from -30°C to +100°C and includes thermal vias for grounding.

Feature Summary

• Voltage-controlled variable equalization utilizing Silicon-On-Insulator (SOI) attenuator technology
• Optimized performance specifically for DOCSIS 3.1 cable modem applications
• Integrated thermal dissipation via backside paddle requiring via connections

Applications

• DOCSIS 3.1 cable modem upstream/downstream signal conditioning
• CATV network signal equalization
• RF front-end linear equalization modules

Procurement Notes

Verify the specific suffix 'SR' indicates the reel or cut-tape packaging configuration as listed by distributors. Confirm RoHS compliance status directly with the manufacturer datasheet Rev.G. Ensure the MCM-14 package footprint matches your PCB design, particularly noting the requirement for vias under the backside paddle for proper RF/DC grounding and thermal management.

Selection Notes

Select this component when designing systems requiring precise slope control between 45 MHz and 1.22 GHz. It is suitable for applications needing low supply current (2 mA) and high linearity. Consider the 75-ohm system impedance compatibility. Evaluate the need for voltage-controlled adjustment versus fixed equalization solutions based on the specific channel plan requirements of the target deployment.

Part Context

The QPC7336 series represents Qorvo's solution for advanced cable broadband infrastructure. As part of the RF miscellaneous ICs category, it addresses the increasing bandwidth demands of modern hybrid fiber-coaxial networks. The SR variant denotes the specific tape-and-reel or cut-tape packaging format available through authorized distribution channels.
