Hittite Microwave Corporation, represented by ASD Technology in Australia and New Zealand, has introduced the first logarithmic detector/controller product within the company’s new leading edge Power Detector Product Line. The HMC600LP4 (E) is ideal for RF power measurement and control in cellular/3G, Telematic, WiMAX and WiBro applications over the 50 MHz to 4 GHz frequency range.
The HMC600LP4(E) Logarithmic Detector/Controller is fabricated in a SiGe BiCMOS process, and converts RF signals at its differential input to a proportional output DC voltage. The HMC600LP4 (E) delivers a high ±3 dB dynamic range of up to 75 dB, with outstanding accuracy and temperature stability from 50 to 4000 MHz.
In logarithmic detection mode the HMC600LP4(E) provides a nominal logarithmic slope of 19 mV/dB . The RF input is internally matched to 50 Ohms, and the device will operate with a supply voltage range of + 2.7V to +5.5V, consuming only 30 mA.
