Avantek UTA-9665 RF Amplifier 10-500MHz 11dB Gain SMA Broadband Module

Avantek UTA-9665 RF Amplifier 10-500MHz 11dB Gain SMA Broadband Module

The Avantek UTA-9665 is a compact connectorized broadband RF amplifier module covering 10 to 500 MHz, delivering 11 dB of gain at 500 MHz. Manufactured by Avantek in Santa Clara, California, this small-form gain block is housed in a rugged shielded metal enclosure with SMA female connectors on both the input and output ends. It is suited for inline signal amplification in RF test setups, laboratory signal chains, and embedded RF system designs.

Applications

Broadband RF amplifier modules like the Avantek UTA-9665 are used as gain blocks in RF and microwave signal chains, where a compact, wideband inline amplifier is needed to boost signal levels between components. The 10–500 MHz coverage makes it suitable for a wide range of applications including laboratory test bench setups, signal conditioning in receiver front ends, cable TV and distribution systems, radar and communications research, and general-purpose RF lab work. Avantek was a leading U.S. manufacturer of microwave and RF semiconductor components and modules from the 1960s through the 1990s, known for high-quality GaAs and bipolar RF amplifier products widely used in defense, telecommunications, and test instrumentation. The company was later acquired by Hewlett-Packard and its RF/microwave product lines folded into what became Agilent Technologies. Original Avantek connectorized amplifier modules remain actively sought by engineers maintaining legacy RF systems and by hobbyists and experimenters working with RF signal chains in the 10–500 MHz range.
