Attenuator 100 to 2000 MHz Technical Data UTF-030 Features Description Pin Configuration • 40 dB Attenuation Range UTF-030, TO-8F • AGC Circuits The UTF-030 is a thin-film voltagecontrolled RF attenuator that offers a continuously-variable attenuation of up to 30 to 45 dB from 100 to 2000 MHz. Utilizing PIN diodes, attenuation over frequency typically has ±0.5 to ±1.0 dB flatness over the complete control voltage range. The UTF-030 comes hermetically sealed in a TO-8 case, a surface mount PlanarPak, or the connectorized TC-1 package.

UTFC – 025 – 1 Model Number Prefix UTFCConnector Option For TC-1 case, the only connector option available is the -1. The -1 option consists of an SMA Female connector on both the input and output (see note). Model Number Note: No R-Series screening is available in the TC-1 case as the case is non-hermetic.
