Frequently Asked Questions
What is the 3 dB bandwidth of the LMH6881SQ/NOPB?
The LMH6881SQ/NOPB has a nominal 3 dB bandwidth of 2400 MHz (2.4 GHz). This wide bandwidth makes it suitable for amplifying high-frequency differential signals in RF receivers, wideband data converters, and test equipment operating across the UHF and microwave frequency ranges.
How is the gain of the LMH6881SQ/NOPB controlled?
The LMH6881SQ/NOPB features a programmable gain control interface that allows gain to be set digitally. This eliminates the need for external resistor networks traditionally used to set amplifier gain, reducing component count and enabling dynamic gain adjustment under software control for adaptive receiver architectures.
What amplifier architecture does the LMH6881SQ/NOPB use?
The LMH6881SQ/NOPB uses a voltage-feedback amplifier architecture with internal frequency compensation. Voltage-feedback topology offers wide bandwidth and good distortion performance, while the integrated compensation simplifies application circuit design by removing the need for external frequency shaping components.
What package is the LMH6881SQ/NOPB available in?
The LMH6881SQ/NOPB is housed in a 24-pin QFN package (JESD-30 code S-PQCC-N24) with an exposed thermal pad. The small footprint and low-inductance leads of the QFN package are critical for maintaining signal integrity at GHz frequencies, while the exposed pad aids heat dissipation.
What are typical applications for the LMH6881SQ/NOPB?
Typical applications include IF amplification in wireless base stations, gain stages in software-defined radio receivers, ADC driver amplifiers in test and measurement equipment, and signal conditioning in medical ultrasound and imaging systems. Its programmable gain feature is especially valuable in automatic gain control (AGC) loop implementations.
