GENERAL DESCRIPTION
receivers. Six stages (3 chip carriers) can be cascaded to form
a very wideband logarithmic ampifier offering >65dB of input
dynamic range, with pulse handling of better than 25ns. (See
figs 5 and 6.)
(log accuracy) of < 1.0dB, temperature stabilisation and
programmable detector characteristics.
allows the major characteristics of the detector to be
programmed. With six stage strip it is possible to vary the
value of R
error/linearity.
The SL2524 is primarily intended for use in Radar and EW
A six stange strip also offers balanced IF limiting, linearity
The detector has an external resistor set (R

The detector is full wave and good slew rates are achieved
with 2ns rise and 5ns fall times (no video filter). The video
bandwidth of a six stage strip is typically 600MHz (-3dB).

offering phase, frequency and pulse (video) information. A
slight loss of dynamic range (2dB) will be observed when the
IF ports are used in conjunction with the video.
The amplifier also offers balanced IF limiting, low phase
The IF and Video ports can be used simultaneously, so
