HMC662LP3_09

HMC662LP3E v00.0309 54 dB, LOGARITHMIC DETECTOR, 8 - 30 GHz Typical Applications The HMC662LP3E is ideal for: • Point-to-Point Microwave Radio • VSAT • Wideband Power Monitoring • Receiver Signal Strength Indication (RSSI) • Test & Measurement Features Wide Input Bandwidth: 8 to 30 GHz Wide Dynamic Range: >54 dB up to 28 GHz Single Positive Supply: +3.3V Excellent Stability Over Temperature Fast Rise/Fall Time: 5ns / 10ns 16 Lead 3x3mm SMT Package: 9mm2 12 Functional Diagram General Description The HMC662LP3E Logarithmic Detector converts RF signals at its input, to a proportional DC voltage at its output. The HMC662LP3E 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 square law detectors is summed, converted into the voltage domain and buffered to drive the LOG OUT output. The HMC662LP3E provides a nominal logarithmic slope of +13 mV/dB and an intercept of -127 dBm at 18 GHz. Ideal as a log detector for high volume microwave radio and VSAT applications, the HMC662LP3E is housed in a compact 3x3 mm RoHS compliant SMT plastic package.
