The LMH2110TM\/NOPB is an 8 GHz logarithmic RMS power detector manufactured by Texas Instruments, featuring a 45 dB dynamic range in a tiny 6-bump DSBGA (YFQ) package. The device provides a temperature-insensitive output voltage that is linear-in-dB with respect to RF input power, making it particularly suited for accurate power measurement of modulated signals with high peak-to-average ratios such as W-CDMA and LTE.<\/p>\n

Its RMS measurement topology inherently ensures modulation-insensitive power readings, making it ideal for W-CDMA, LTE, and other high-PAR signal environments. The device provides an output voltage linearly proportional to the RF input power in dBm, with excellent log conformance better than +\/-0.5 dB and temperature stability of +\/-0.25 dB. Operating from a single 2.7V to 5V supply and consuming only 4.8 mA typical, the LMH2110 is packaged in a tiny 6-bump DSBGA for space-constrained applications.","working_principle":"The LMH2110 uses a logarithmic RMS detection architecture consisting of a cascaded chain of limiting amplifier stages with rectifying detectors at each stage. The RF input signal is internally terminated with 50 ohms and amplified through the limiting chain. At each stage, the signal is partially rectified, and the combined rectified outputs produce a logarithmic (linear-in-dB) relationship between the output voltage and the RF input power. The RMS computation is performed by the integrated square-law detector and low-pass filter, ensuring that the output is proportional to the true RMS power regardless of the signal modulation. The enable (EN) pin controls shutdown mode, during which the output becomes high-impedance.","pin_description":"\n
