Hittite Microwave Corporation 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. The HMC1010LP4E offers 60 dB dynamic range over DC to 3.9 GHz. The HMC909LP4E offers a broadband single-ended RF input with 40 dB dynamic range over DC to 5.8 GHz. Both products have improved modulation performance and power dissipation coupled with an industry first 4-bit programmable integration bandwidth control interface eliminating the need for cumbersome analog control voltages. Developed 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 37mV/dB and a nominal intercept of -68 dBm. The HMC1010LP4E exhibits superior detection accuracy of ±1dB compared with any RMS detector in the market for about the same price point. 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. It exhibits less than 0.1 dB modulation error at 900 MHz, 1900 MHz, 2200 MHz, and 3500 MHz and 0.4 dB at 5800 MHz.
