专业维修intra action的射频产品。 美国intraaction公司是一家专业研究高频放大器和信号发生器的生产商。me系列的产品是集信号发生器和射频放大器与一体的放大器,产品型号系列me-40(40mhz)_me2001(200mhz),参数如下: DESCRIPTION The Model ME series Modulator Drivers include a crystal controlled RF oscillator, fast modulation circuit, and a broadband RF power amplifier in a housing with power supply, RFI line filter, and line switch. The standard crystal controlled oscillator has a calibration tolerance of 25 ppm. Crystals at other than the specified frequencies can be factory installed. The standard modulation input configuration is analog with a digital input option available. A cw RF output level is adjusted by the front panel level control which inserts a dc offset to the input of the modulation circuit with no modulation input voltage. The class AB broadband amplifier has sufficient bandwidth for pulsed operation. RF output power capability can be up to 10 watts for some models. Configuration options include a front panel user accessible connection between the oscillator and modulation circuit (N) so that an external source frequency can be used in place of the internal crystal oscillator. Also available is an optional front panel connection between the modulation circuit and the RF power amplifier (H) to give the Model ME drivers capability to be used as a stand alone RF power amplifier. Drivers with option E provide a cw +10 dBm crystal oscillator reference output.
