DLVAs/SDLVAs

Teledyne Microwave Solutions (TMS) has extensive experience in the design and manufacture of Detector Log Video Amplifiers (DLVAs) and Successive Detector Log Video Amplifiers (SDLVAs). These devices are used extensively in applications requiring an output voltage related to the power of a received RF signal. In order to cope with a wide range of input signals a log amplifier is used to provide a linear voltage output per dBm of input power. Typically the input range of a DVLA will operate over 50dB or more with a base sensitivity less than -40dBm whilst providing linear conversion within ±1dB for all power levels, frequencies and temperatures. Where greater sensitivity and power levels are expected the Extended Range DLVA (ERDLVA) offers even greater performance.
