Power Detector HMC714LP5E

January 17, 2011

The HMC714LP5E is a dual-channel RMS power detector designed for high accuracy RF power signal measurement and control applications from 0.1 to 3.9 GHz. Ideal for dual-channel wireless infrastructure systems, the HMC714LP5E can be used with input signals having RMS values from -55 dBm to +15 dBm and large crest factors with no accuracy degradation. Each RMS detection channel is fully specified for operation up to 3.9 GHz, over a 70 dB dynamic range.

The HMC714LP5E provides two linear-in-dB detection outputs with scaled slopes of 37 mV/dB, and a read of average input signal power, or 'true-RMS' power with excellent channel matching of less than 0.5 dB over a wide range of input frequencies, and with low temperature drift.

Operating from a +5V supply, the HMC714LP5E is specified for operation from -40°C to +85°C, and is supplied in a compact 5x5 mm, RoHS compliant leadless SMT package.
