HMC1020LP4E

HMC1020LP4E v02.0511 RMS POWER DETECTOR SINGLE-ENDED, DC - 3.9 GHz 11 Typical Applications The HMC1020LP4E is ideal for: Log –> Root-Mean-Square (RMS) Conversion Tx/Rx Signal Strength Indication (TSSI/RSSI) RF Power Amplifier Efficiency Control Receiver Automatic Gain Control Transmitter Power Control Features Broadband Single-Ended RF Input ±1 dB Detection Accuracy to 3.9 GHz Input Dynamic Range: -65 dBm to +7 dBm RF Signal Wave Shape & Crest Factor Independent Digitally Programmable Integration Bandwidth Excellent Temperature Stability Power-Down Mode 24 Lead 4x4mm SMT Package: 16mm² Power Detectors - SMT 11 - 1 Functional Diagram General Descriptions The HMC1020LP4E Power Detector is designed for RF power measurement and control applications for frequencies up to 3.9 GHz. The detector provides an accurate RMS representation of any broadband, single-ended RF/IF input signal. The output is a temperature compensated, monotonic representation of real signal power, measured with an input sensing range of 72 dB. The HMC1020LP4E 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. The integration bandwidth of the HMC1020LP4E is digitally programmable with the use of input pins SCI1-4 over a range of more than 3 decades. This allows the user to dynamically set the operation bandwidth and also permits the detectio...
