The UTO-547 from Teledyne Microwave Solutions is thin-film cascadable amplifier with 10 to 500 MHz frequency range, low noise 2.8 dB (Typ), high output power +19.0 dBm (Typ) and medium gain 12.5 dB (Typ). Thin-film RF bipolar amplifier using lossless feedback for optimum noise figure and high dynamic range, and active bias to compensate for temperature and voltage variations. Internal blocking capacitors couple the RF through the amplifier. The UTO-547 comes in TO-8 hermetic case.
