HMC1094

Data Sheet FEATURES Wide input bandwidth: 1 to 23 GHz Wide dynamic range: 50 dB up to 23 GHz Single positive supply: 3.3 V Excellent stability over temperature Fast rise/fall time: 12 ns/65 ns 16-lead 3 mm × 3 mm SMT package: 9 mm² APPLICATIONS Point-to-point microwave radio VSAT Wideband power monitoring Receiver signal strength indication (RSSI) Test and measurement GENERAL DESCRIPTION The HMC1094 logarithmic detector converts RF signals at its input to a proportional dc voltage at its output. The HMC1094 employs successive compression topology that 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, con- 50 dB, Logarithmic Detector, 1 GHz to 23 GHz HMC1094 FUNCTIONAL BLOCK DIAGRAM 16 VCC 15 VCC 14 VCC 13 VCC GND 1 RFIN 2 GND 3 RSV 4 BIAS AND CONTROL CIRCUIT DET DET DET HMC1094 ...
