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. It can be used in all popular communications standards: 2.
