Thin-Film Cascadable Amplifier
5 to 500 MHz
Technical Data
UTO/UTC 524 Series
Features
• Frequency Range: 5 to
500 MHz
• High Gain: 31.0 dB (Typ)
• Medium Output Power:
+17.0 dB (Typ)
• Temperature Compensated
Description
The 524 Series is a high-power,
low-noise amplifier. This two-
stage RF amplifier is built on a
thin-film substrate and is compen-
sated for temperature and bias
variations, by using resistive
feedback and active bias. Blocking
capacitors couple the RF through
the amplifier. The 524 Series is
available in either the TO-8
hermetic case or connectored
TC-1 package.

For TC-1 case the only connector option
available is the -1. The -1 option consists
of a SMA Female connector on both the
input and output (see note).
Model Number
Note: R-Series screening is not available in the TC-1 case as the case is non-hermetic.
