Thin-Film Cascadable Amplifier
10 to 100 MHz
Technical Data
UTO/UTC 111 Series
Features
• Frequency Range: 10 to
100 MHz
• Low Noise: 1.4 dB (Typ)
• Medium Power: 16.8 dBm
(Typ)
• Temperature Compensated
Description
The 111 Series is a single-stage,
high-gain silicon bipolar amplifier
that incorporates thin-film tech-
nology. Low noise figure and high
efficiency are the result of an
output transformer coupling
design. Active bias circuits
provide temperature compensa-
tion and increased immunity to
bias voltage variations. Blocking
capacitors couple the RF through
the amplifier, while a low VSWR is
maintained through unique
transformer designs. The 111
Series is available in either the
TO-8 hermetic package or the
connectored TC-1A package.

Connector Option
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.
