A 0.1 to 2.5 GHz Logarithmic Amplifier for RF Detection Analog Devices Wilmington, MA Logarithmic amplifiers typically are used to measure widely varying signal levels at high frequencies. These signals may vary in amplitude by 90 to 100 dB at frequencies to 3500 MHz. In addition, some log amplifiers...

A Ka-band Linearizer for TWTAs Linearizer Technology Inc. Hamilton, NJ Even though traveling-wave tube amplifiers (TWTA) offer the best high power amplifier performance at high frequencies in terms of power, efficiency, size and cost, they lag behind solid-state power amplifiers in terms of linearity. Thus, some type of linearizer...
