HMC-C054
v00.0608
RMS POWER DETECTOR
70 dB, 0.01 - 2 GHz
Features
±1 dB Detection Accuracy to 2 GHz
Input Dynamic Range: -70 dBm to +10 dBm
RF Signal Wave Shape & Crest Factor Independent
+12V Operation from -55°C to +85°C
Excellent Temperature Stability
Typical Applications
Power-Down Mode
The HMC-C054 is ideal for:
Field Replaceable SMA Female Connectors
• Log –> Root-Mean-Square (RMS) Conversion
• Received Signal Strength Indication (RSSI)
7
• Transmitter Signal Strength Indication (TSSI)
General Description
• RF Power Amplifier Efficiency Control
The HMC-C054 Power Detector is designed for RF
power measurement, and control applications for
frequencies up to 2 GHz. The detector provides a
“true RMS” representation of any RF/IF input signal.
The output is a temperature compensated monotonic,
representation of real signal power, measured with an
input sensing range of 70 dB.
POWER DETECTORS
• Receiver Automatic Gain Control
• Transmitter Power Control
Functional Diagram
The HMC-C054 is ideally suited to those wide bandwidth, wide dynamic range applications, requiring repeatable measurement of real signal power,
especially where RF/IF wave shape and/or crest factor
change with time.
