LTC5583
Matched Dual-Channel
6GHz RMS Power Detector
FEATURES DESCRIPTION n The LTC®5583 is a dual-channel RMS power detector,
capable of measuring two AC signals with wide dynamic
range, from –59dBm to 4dBm, depending on frequency.
Each AC signal’s power in decibel-scaled value is precisely
converted to a DC voltage on a linear scale, independent
of the crest factor of the input signal waveforms. The
LTC5583 is suitable for precision power measurement and
level control for a variety of RF standards, including LTE,
EDGE, W-CDMA, CDMA2000, TD-SCDMA, and WiMAX. Frequency Range: 40MHz to 6GHz
Linear Dynamic Range: Up to 60dB
±0.5dB (Typ) Accuracy Over Temperature
40dB Channel-to-Channel Isolation at 2GHz Even
with Single-Ended RF Inputs
Matched Dual-Channel Outputs: 55dB with differential inputs. APPLICATIONS n VSWR Monitor
MIMO Transmit Power Control
Basestation PA Control
Transmit and Receive Gain Control
RF Instrumentation The power difference of the two input signals is provided
at a difference output pin. Each channel also has a fast
envelope detector, which tracks the RF input signal’s envelope and outputs a voltage directly proportional to the …
