Description
The UTF-025 is a thin-film voltage-
controlled RF attenuator that
operates from 5 to 2500 MHz.
Utilizing PIN diodes, attenuation
over frequency typically has ±0.4
to ±0.6 dB flatness over the
complete control voltage range.
On the average, the attenuation
will change roughly 5 dB per 2-
volt increment. The UTF-025 is
available in either the TO-8
hermetic case or connectorized
TC-1 package.
