1 Typical Applications The is ideal for: Point-to-Point Microwave Radio VSAT Wideband Power Monitoring Receiver Signal Strength Indication (RSSI) Test & Measurement Functional Diagram Features Wide Input Bandwidth: 8 to GHz Wide Dynamic Range: >54 db up to 8 GHz Single Positive Supply: +.V Excellent Stability Over Temperature Fast Rise/Fall Time: 5ns / ns 6 Lead xmm SMT Package: 9mm² General Description The Logarithmic Detector converts RF signals at its input, to a proportional DC voltage at its output. The employs successive compression topology which delivers high dynamic range over a wide input frequency range. As the input power is increased, successive amplifiers move into saturation one by one creating an approximation of the logarithm function. The output of a series of detectors is summed, converted into the voltage domain and buffered to drive the LOG OUT output. The provides a nominal logarithmic slope of + mv/db and an intercept of -7 dbm at 8 GHz. as a log detector for high volume microwave radio and VSAT applications, the is housed in a compact x mm RoHS compliant SMT plastic package.
