QPC7335SR

Overview

The QPC7335SR is a voltage-controlled variable equalizer manufactured by Qorvo, designed for high-linearity RF applications. It operates within a frequency bandwidth of 45 MHz to 1002 MHz and utilizes an SOI attenuator technology optimized for DOCSIS 3.1 downstream path operations. The device features a single channel with a 75-ohm system impedance and provides up to 22 dB of attenuation. It is housed in a surface-mount MCM-14 package (6.0 mm x 6.0 mm) and supports operation temperatures ranging from -30°C to +100°C.

Procurement Notes

Verify the specific suffix 'SR' against official Qorvo documentation to confirm reel packaging specifications and tape-and-reel dimensions. Ensure the procurement order matches the exact part number variant required for your manufacturing process. Cross-reference the datasheet revision history to confirm compatibility with current production standards and RoHS compliance status before finalizing purchase orders.

Selection Notes

Select this component when designing systems requiring precise amplitude equalization in the 45 MHz to 1002 MHz range. It is suitable for 75-ohm environments typical in cable infrastructure. Consider the thermal operating range and package size constraints during PCB layout. Validate that the control voltage requirements align with your system's available drive signals for optimal equalization performance.

Part Context

The QPC7335SR belongs to Qorvo's portfolio of RF linear equalizers, specifically engineered for cable broadband applications. It complements other Qorvo components like the QPC7336SR, which covers a slightly extended frequency range up to 1.218 GHz. These devices are integral to maintaining signal integrity in modern DOCSIS 3.1 networks, ensuring accurate data delivery over coaxial infrastructure.

Replacement Considerations

The QPC7336SR is a documented alternative offering a wider frequency range up to 1.218 GHz. Verify pinout compatibility and control voltage specifications before substitution. Ensure the replacement meets the specific impedance and attenuation requirements of the target circuit design.
