DUAL RMS POWER DETECTOR DC - 3.9 GHz General Description
The HMC1030LP5E is a dual-channel RMS power detector designed for high accuracy RF power signal measure- ment and control applications over the 0.1 to 3.9 GHz frequency range. The device can be used with input signals hav- ing RMS values from -60 dBm to +10 dBm referenced to 50 Ohm and large crest factors with no accuracy degradation. Each RMS detection channel is ful y specified for operation up to 3.9 GHz, over a wide dynamic range of 70 dB. The HMC1030LP5E operates from a single +5V supply and provides two linear-in-dB detection outputs at the RMSA and RMSB pins with scaled slopes of 37 mV/dB. The RMSA and RMSB channel outputs provide RMS detection perfor- mance in terms of dynamic range, logarithmic linearity and temperature stability similar to Hittite’s HMC1021LP4E RMS Detector. The RMSA and RMSB outputs provide a read of average input signal power, or true-RMS power. Frequency detection up to 3.9 GHz is possible, with excel ent channel matching of less than 1 dB, over a wide range of input frequencies and with low temperature drift. The HMC1030LP5E also provides “channel difference” output ports via pins OUTP and OUTN, permitting measure- ments of the input signal power ratio between the two power detection channels. These outputs may be used in single-ended or differential configurations. An input voltage applied to the VLVL input pin is used to set the common 11 mode voltage reference level for OUTP and OUTN. On the Hittite evaluation board, the VLVL pin is shorted to VREF2 output to provide a nominal bias voltage of 2.5V; but any external bias voltage may be used to set VLVL. T The HMC1030LP5E features ETA and ETB pins which provide an accurate voltage output which is linearly propor- tional to the envelope amplitude of the RF input signal for modulation bandwidths up to 150 MHz. The high bandwidth M envelope detection of the HMC1030LP5E makes it ideal for detecting broadband and high crest factor RF signals S commonly used in CDMA2000, WCDMA, and LTE systems. Additional y, the instantaneous envelope output can be - used to create fast, excessive RF power protection, PA linearization, and efficiency enhancing envelope tracking PA implementations. RS The HMC1030LP5E includes a buffered PTAT temperature sensor output with a temperature scaling factor of 2 mV/°C O yielding a typical output voltage of 567 mV at 0°C. T The HMC1030LP5E operates over the -40 to +85°C temperature range, and is available in a compact, 32-lead 5x5 C mm leadless QFN package. TE E
