LINEAR PRE-AMPLIFIER FOR RADIO-FREQUENCY POWER AMPLIFIERJeanCharles GRASSETChristophe PINATEL
The power-amplifier usually has the requirement to provide buck and boost and from a single-cell Li-ion battery with an operating range of 3-4.2V. A DC-DC regulator is best suited to vary the Collector-Bias voltage of the PA in order to improve the PA efficiency when it is not ...

The 2020 International Microwave Symposium (IMS), this year, will be held in Los Angeles, California from 21 to 26 June. This year one of the projects in the Student Design Competition is the designing of ‘Linear High Power Amplifier (HPA)’. The compet
The present invention relates to a driving technology of an ion mobility device, and more particularly, to a waveform generating device for a high voltage asymmetric field ion mobility spectrometer (FAIMS) using an ultra wide band radio frequency (RF) linear amplifier and a method thereof. The ...

The signal was amplified using a power amplifier before delivering to the horn to compensate the free space and cables losses, and ensure good receiving power levels above the noise floor of the measurement setup [45]. On the basis of the direct comparison method using a third horn with ...
This compact little amplifier is the brain-child of Pat Murdoch, ZL1AXB, in Auckland, New Zealand. It is only 11″ wide, 4″ high, and 9″ deep. In most respects it is a typical grounded grid linear amplifier, with the exception of a rather unique tuned cathode input circuit that was...
The Tokyo Hy-Power HL-700B is a desktop shortwave linear amplifier. It covers 80-10 meters and has an RF output of SSB: 600 W PEP, CW/FM: 500 W, AM: 300 W. It requires 13.8V DC power and has a maximum current drain of 70 A during transmit. The amplifier weighs 8 kg and ...
