Detector Log Video Amplifiers (DLVA)
There are three basic types of logarithmic amplifiers, Detector-Log Video Amplifiers (DLVAs) Successive Detection Logarithmic Amplifiers True Log Amplifiers (TLAs) A detector log video amplifier (DLVA) is a type of logarithmic amplifier in which the envelope of the input RF signal is detected by a standard "linear" diode detector. The output of the detector is compressed in the video amplifier section, making input/output relationship similar to a logarithmic conversion. In general, the DLVA offers the advantage of operating over the widest frequency range, but at the sacrifice of dynamic range. Limited by the detecting range of square law of the input diode detector, typical dynamic range for a DLVA is approximately 40 dB. In quite a lot of usages, two log cascades are put in parallel with a RF amplifier incorporated in time of detection of the log cascade, so that the dynamic range can be extended to approx.70dB. The detected video sections of a DLVA can either be AC coupled, DC coupled, or pseudo DC coupled. Each has its advantages, depending upon the application (i.e., CW operation, temperature compensation, etc.). The basic configuration of a DLVA is simply a detector diode to convert the RF energy into a DC voltage followed by a video amplifier with a logarithmic transfer function. The combination results in a device which compresses a large RF signal range into a narrow range of video voltage. We have put considerable effort into designing a DC coupled DLVA with very low baseline drift. Employing a tunnel diode based detector circuit coupled with a very stable DLVA, high-speed miniature DC DLVA with good recovery characteristics is available.

Terms and Definitions
Operational Bandwidth is the range of input frequency over which the technical specifications of the amplifier are met. Log Slope is the straight line slope of the input/output transfer characteristics of the detected signal over the dynamic range. The log slope is expressed in millivolts per dB of a best-fit straight line as derived by a leastsquares approximation of all data points Log Linearity is the maximum deviation in dB of all measured points from the calculated best-fit straight line. The dynamic range can be as high as 75dB, depending upon Dynamic Range is the range of the input signals in dB over which the output linearity requirement is met. Maximum Input Power is the maximum power that the logarithmic amplifier can withstand without damage.
DL1
DC offset is the residual DC output of a logarithmic amplifier when the input is terminated with 50ohm. Tangential Signal Sensitivity (TSS) defines the input level that results in an output signalto-noise ratio of 6 dB. TSS, which is directly related to noise figure and bandwidth, aids in defining the lower limit of the input dynamic range of a logarithmic amplifier. TSS is also a convenient way of specifying a logarithmic amplifier's noise performance, since noise Rise Time is defined as the time difference between the 10% point and 90% point on the rising leading edge of the output video pulse. Recovery Time for a logarithmic amplifier is defined in many ways by system engineers. The most common is to use multiple pulses and characterize the time between the 90% point on the trailing edge of the first pulse and the 10% point on the leading edge of the
