Linear Power Amplifiers for Point-to-Point Radio ApplicationsBy Sushil KumarKent StoryRon KielmeyerTariq Lodhi
A linear amplifier is installed inline between the antenna output of a CB radio and the antenna connected to the unit. The amplifier takes the output of the radio and boosts the signal, resulting in improved transmission distance in most cases. Linear amplifiers may be designed for home or mob...
Generally, the invention relates to a method and apparatus to improve the performance of radio frequency power amplifiers. More particularly, the present invention discloses the use of a power booster in conjunction with a radio-frequency linear power amplifier to reduce intermodulation distortion of ...
We offer the latest in LDMOS linear amplifier technology for the High Frequency Radio Band at very affordable prices.
Simulation results show less than 1.7% gain error for ±20 ns input time difference range, which is larger than the range of conventional TDAs. The proposed TDA consumes 115.76 μW from a 1.8 V supply.关键词: CMOS integrated circuits amplifiers comparators (circuits CMOS process capacitor ...

Radio Frequency (RF) amplifiers with voltage limiting using non-linear feedback are presented herein. According to one aspect, an RF amplifier comprises an amplifier circuit having an input terminal and an output terminal and a non-linear feedback circuit having an input terminal and an output ...
Outphasing Class-E power amplifiers (OEPAs) using isolating power combiners and an inverse cosine signal component separator are inherently linear but suffer from low efficiency at power back-off. For high efficiency both at maximum output power and at power back-off, non-isolating power combiners...
