Hittite Microwave has launched two new low cost, highly flexible RMS power detectors for RF power measurement/control in Cellular/3G, LTE/WiMAX/4G, broadband, test equipment and military applications between DC and 5.8 GHz. Ideal for the measurement of complex modulated waveforms with large, dynamically changing crest factors, the HMC1010LP4E RMS Power Detector provides 60 dB of dynamic range, a nominal logarithmic slope of 37 mV/dB and a nominal intercept of -68 dBm. The HMC1010LP4E exhibits superior detection accuracy of ±1 dB compared with any RMS detector in the market for a price point of only $1.99 at 10,000 piece volumes. It exhibits less than 0.1 dB modulation error at 900, 1900 and 2200 MHz.
The HMC909LP4E Single-ended RMS Power Detector provides 40 dB of dynamic range, a nominal logarithmic slope of 37 mV/dB and a nominal intercept of -70 dBm over its entire DC to 5.8 GHz range. The HMC909LP4E combines superior detection accuracy and better modulation performance than the competition at a price point of only $1.49 at 10,000 piece volumes. It exhibits less than 0.1 dB modulation error at 900, 1900, 2200 and 3500 MHz and 0.4 dB at 5800 MHz.
Flexibility and dynamic control features have been designed into both the HMC1010LP4E and HMC909LP4E RMS Power Detectors. Both products introduce a new digitally programmable integration bandwidth feature that permits the use of different integration bandwidth settings on the same system platform. Temperature stability is excellent with less than ±1 dB total error from -40° to +85°C maintained over the entire DC to 3.9 GHz frequency band. Both products' RF inputs are externally matched to 50 ohms, operate from a +5 V single supply and are housed in a 44 mm plastic leadless surface-mount package.
