The 50-5-1G is a voltage-controlled oscillator (VCO) that was developed by Raytheon for use in radio communications systems. The VCO is based on the standard 50-M4-4G type design and provides a continuously variable output frequency range from 500 kHz to 5 GHz. It is also equipped with an Amplitude Modulation/Frequency Modulation (AM/FM) mode for signal modulation. This VCO can be used for signal generation in a variety of radio communication systems, including cellular and satellite systems. The VCO is also suitable for digital modulation, such as Quadrature (QAM) and Binary (QPSK), which can be used for various applications including video broadcasting and digital video streaming.
