LINEAR PRE-AMPLIFIER FOR RADIO-FREQUENCY POWER AMPLIFIERJeanCharles GRASSETChristophe PINATEL
We offer the latest in LDMOS linear amplifier technology for the High Frequency Radio Band at very affordable prices.
150W Linear Amplifier ideal for 10m transcievers with Inversion Polarity Protection. Features: Frequency: 20-30 MHz Input Energy/ Power: 14-20A Input Power: 1-5 W Input Power SSB: 2-10 W Output Power: 150 W Max Output Power SSB: 150 W PEP Max ...
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 maximum output power of a single 813 would normally be around 300w PEP below 21 mHz. With approximately 50w input, this amplifier produces 600w PEP output nominally, and around 500w PEP output at 29 mHz. Its intermodulation and harmonic distortion products are well below 40 dB down from ...
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 ...
2.2. Power Amplifier Nonlinearity For energy-efficient communications systems, the PA typically operates close to its saturation point, leading to significant nonlinear distortions and short-term memory effects. Thus, the PA nonlinear behavior results in spectral regrowth and new harmonic components at mu...
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 ...
