54 dB, LOGARITHMIC DETECTOR, 1 - 23 GHz Typical Applications Features
The HMC948LP3E is ideal for: Wide Input Bandwidth: 1 to 23 GHz T • Point-to-Point Microwave Radio Wide Dynamic Range: 54 dB up to 23 GHz M • VSAT Single Positive Supply: +3.3V S • Wideband Power Monitoring Excellent Stability Over Temperature - • Receiver Signal Strength Indication (RSSI) Fast Rise / Fall Time: 5 / 7 ns RS • Test & Measurement 16 Lead 3x3 mm SMT Package: 9 mm² O T C TE
Functional Diagram General Description
E The HMC948LP3E Logarithmic Detector converts D RF signals at its input, to a proportional DC voltage R at its output. The HMC948LP3E employs successive compression topology which delivers high dynamic WE range over a wide input frequency range. As the input O power is increased, successive amplifiers move into P saturation one by one creating an approximation of the logarithm function. The output of a series of square law detectors is summed, converted into the voltage domain and buffered to drive the LOG OUT output. The HMC948LP3E provides a nominal logarithmic slope of +14.2 mV/dB and an intercept of -111 dBm at 23 GHz. Ideal as a log detector for high volume micro- wave radio and VSAT applications, the HMC948LP3E is housed in a compact 3x3 mm RoHS compliant SMT plastic package.
