QPC7338SR

Overview

The QPC7338SR is a cable compensated voltage-controlled variable equalizer manufactured by Qorvo. It employs an SOI attenuator to provide an inverse cable loss frequency response, effectively compensating for signal degradation in broadband networks. The device operates within a bandwidth of 108 MHz to 1794 MHz and offers an 18 dB slope range. Designed for CATV applications, it functions with a 5V supply and features low insertion loss. The component is housed in a 14-QFN (6x6) package.

Feature Summary

• Provides inverse cable loss frequency response to compensate for broadband network attenuation
• Utilizes Silicon-On-Insulator (SOI) attenuator technology for precise control
• Operates across a wide frequency range from 108 MHz to 1794 MHz
• Features low insertion loss for efficient signal transmission

Applications

• Cable Television (CATV) systems
• Broadband network infrastructure
• RF signal compensation modules

Procurement Notes

Verify the specific suffix 'SR' indicates the reel packaging configuration as documented by distributors. Confirm that the 14-QFN (6x6) footprint matches the target PCB design requirements. Ensure the 5V supply voltage aligns with the system power architecture. Check for moisture sensitivity handling instructions if storage conditions exceed specified limits. Validate the operational temperature range against environmental constraints.

Selection Notes

Select this component when designing systems requiring active compensation for frequency-dependent cable losses in the 108 MHz to 1794 MHz range. The 18 dB slope range allows for significant adjustment to match varying cable lengths. Consider the 14-QFN package size for space-constrained layouts. Ensure the control interface supports the required voltage modulation for tilt adjustment.

Part Context

The QPC7338SR belongs to Qorvo's family of voltage-controlled variable equalizers, which also includes models like the QPC7336SR and QPC7339. These devices are engineered to maintain signal integrity in RF distribution networks by counteracting the natural high-frequency attenuation inherent in coaxial cables. They are distinct from fixed attenuators or amplifiers, offering dynamic tilt control.

Replacement Considerations

The QPC7338SB is a confirmed substitute part number with identical specifications, including the 108–1794 MHz bandwidth and 18 dB slope range. Verify pinout compatibility and package dimensions before substitution.
