Description
The UTF-035 is a thin-film voltage-
controlled RF attenuator that
operates from 50 to 2000 MHz.
The RF attenuation will change a
fixed increment of nearly 3 dB per
volt, over the full control voltage
range. Utilizing PIN diodes, device
attenuation vs. voltage linearity is
typically ±0.6 dB flat over the
complete control voltage range.
The UTF-035 is only unique
because the linearizer is housed in
the same single TO-8 package
weighing 2.1 grams.
