Thin-Film Cascadable Amplifier
10 to 500 MHz
Technical Data
UTO/UTC 526 Series
Features
• Frequency Range: 10 to
500 MHz
• High Gain: 28.0 dB (Typ)
• Medium Output Power:
+21.0 dBm (Typ)
• Temperature Compensated
Description
The 526 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 526 Series is
available in either the TO-8
hermetic case or connectored
TC-1 package.
