HMC610LP4E

HMC610LP4 / 610LP4E v02.0607 70 dB RMS POWER DETECTOR, DC - 3.9 GHz Typical Applications The HMC610LP4(E) is ideal for: Cellular / PCS / 3G WiMAX, WiBro, Fixed Wireless, & Military RF & Microwave Instrumentation www.DataSheet4U.com Features Accurate RMS-to-DC Conversion: DC to 3.9 GHz[1] Input Dynamic Range of >70 dB: -60 to +10 dBm in 50 Ohms Waveform & Modulation Independent: GSM / CDMA / TDMA Linear-in-dB Output: Scaled 37 mV/dB Operates from 4.5 to 5.5V from -40°C to +85°C Power-Down Mode Compact 4x4mm Leadless SMT Package 8 Power Amplifier Linearization / Control Loops Transmitter Power Control Transmitter Signal Strength Indication POWER DETECTORS - SMT Functional Diagram General Description The HMC610LP4(E) is a true RMS power detector capable of providing a ±1 dB measurement dynamic range of more than 70 dB. It converts any RF input signal at its differential input, regardless of modulation or waveform complexity, to an accurately scaled linearin-dB output response that is equivalent to the RootMean-Square (RMS) of the input waveform. For normal operation, the RMSOUT pin is shorted to the VSET input, and will provide a nominal logarithmic slope of 37 mV/dB and an intercept of -70 dBm for frequencies up to 2 GHz; other slopes are achieved with external resistors connected between RMSOUT and VSET pins. Temperature stability is excellent with ±0.5 dB error from -40°C to 85°C maintained from 100 MHz to 3.9 GHz. Electrical Specifications, TA = +25C, Vc...
