Description
Description
Overview
GAOTek ultra-wideband 9K-250MHz 300W high-gain RF amplifier chassis is designed for ultra-wideband applications, covering a broad frequency range of 9K-250MHz. Delivering a high PSAT power output of 300W, it ensures reliable performance for demanding test and measurement scenarios. With a gain of 57 dB and power gain flatness of 4 dB, the amplifier provides stable signal transmission while maintaining low distortion. It also features low spurious signals at -65 dBc and harmonic signals at -15 dBc, ensuring minimal interference and clean signal output. Housed in a rugged 19-inch rackmount chassis (482x600x223 mm), this compact and durable amplifier is ideal for various installation environments.
