Key Features
- Broadband 5 MHz to 6000 MHz operating range covers cellular, Wi-Fi, and sub-6 GHz 5G bands in a single SMT attenuator
- 31.5 dB digital attenuation control with a maximum insertion loss of only 2.4 dB enables precise signal-level adjustment without significant signal degradation
- 30 dBm maximum input power handling at 50 ohm characteristic impedance supports use in high-power RF signal path and test equipment applications
Applications
The QPC6614SR is designed for RF signal path attenuation in cellular base stations, wireless test equipment, and software-defined radio platforms operating across the 5 MHz to 6000 MHz frequency range. Its 31.5 dB digitally controlled attenuation range and 30 dBm power handling also make it a strong fit for automatic gain control loops in LTE and sub-6 GHz 5G transceivers, as well as in wireless infrastructure and spectrum analyzer front-end circuits where precise, programmable attenuation is required.

Frequently Asked Questions
Which frequency bands does the QPC6614SR cover, and how does that make it suitable for multi-band 5G sub-6 GHz designs?
The QPC6614SR operates from 5 MHz to 6000 MHz, spanning all major sub-6 GHz 5G NR bands including n41 (2.5 GHz), n77 and n78 (3.3 GHz to 3.8 GHz), and n79 (4.4 GHz to 5 GHz), as well as LTE, Wi-Fi 2.4 GHz, and Wi-Fi 5 GHz bands, enabling a single attenuator design to cover multiple radio access technologies.
How does the 30 dBm input power rating of the QPC6614SR compare to requirements in base station or test equipment signal paths?
A 30 dBm (1 W) maximum input power rating is sufficient for the attenuator position downstream of a driver amplifier in most small-cell base station and bench test equipment applications, where typical drive levels are 20 dBm to 27 dBm; designs exceeding 30 dBm input power would need an external high-power attenuator ahead of the QPC6614SR.
What insertion loss does the QPC6614SR add at minimum attenuation, and how should that be budgeted in an RF signal chain?
At minimum attenuation setting, the QPC6614SR exhibits a maximum insertion loss of 2.4 dB across its 5 MHz to 6000 MHz operating range at 50 ohm impedance, which should be included as a fixed loss budget item in the RF chain gain plan, typically compensated by 2 dB to 3 dB of additional amplifier gain upstream or downstream of the attenuator.
