LMH2121 Datasheet Fast-responding Linear Power Detector

Manufacturer: Texas Instruments

Overview: LMH2121 www.ti.com SNVS876A – AUGUST 2012 – REVISED MARCH 2013 LMH2121 3 GHz Fast-Responding Linear Power Detector with 40 dB Dynamic Range Check for Samples:.

General Description

The LMH2121 is an accurate fast-responding power detector / RF envelope detector.

Its response between an RF input signal and DC output signal is linear.

The typical response time of 165 ns makes the device suitable for an accurate power setting in handsets during a rise time of RF transmission slots.
