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.
It can be used in all popular communications
standards: 2G/3G/4G/WAP.
The LMH2121 has an input range from ?28 dBm to
+12 dBm. Over this input range the device has an
intrinsic high insensitivity for temperature, supply
voltage and loading. The bandwidth of the device is from 100 MHz to 3 GHz, covering 2G/3G/4G/WiFi
wireless bands.
As a result of the unique internal architecture, the
device shows an extremely low part-to-part variation
of the detection curve. This is demonstrated by its low
intercept and slope variation as well as a very good
linear conformance. Consequently the required characterization and calibration efforts are low.
The device is active for EN = High; otherwise it is in a
low power consumption shutdown mode. To save
power and allow for two detector outputs in parallel,
the output (OUT) is high impedance during shutdown.
The LMH2121 is offered in a tiny 4-bump DSBGA
package: 0.866 mm x 1.07 mm x 0.6 mm.
