Description
- Product Details
- The AD8364 is a true rms, responding, dual-channel RF power measurement subsystem for the precise measurement and control of signal power. The flexibility of the AD8364 allows communications systems, such as RF power amplifiers and radio transceiver AGC circuits, to be monitored and controlled with ease. Operating on a single 5 V supply, each channel is fully specified for operation up to 2.7 GHz over a dynamic range of 60 dB. The AD8364 provides accurately scaled, independent, rms outputs of both RF measurement channels. Difference output ports, which measure the difference between the two channels, are also available. The on-chip channel matching makes the rms channel difference outputs extremely stable with temperature and process variations. The device also includes a useful temperature sensor with an accurately scaled voltage proportional to temperature, specified over the device operating temperature range. The AD8364 can be used with input signals having rms values from −55 dBm to +5 dBm referred to 50 Ω and large crest factors with no accuracy degradation.
- Integrated in the AD8364 are two matched AD8362 channels (see the AD8362 data sheet for more information) with improved temperature performance and reduced log conformance ripple. Enhancements include improved temperature performance and reduced log-conformance ripple compared to the AD8362. On-chip wide bandwidth output operational amplifiers are connected to accom-modate flexible configurations that support many system solutions.
- The device can easily be configured to provide four rms measurements simultaneously. Linear-in-dB rms measurements are supplied at OUTA and OUTB, with conveniently scaled slopes of 50 mV/dB. The rms difference between OUTA and OUTB is available as differential or single-ended signals at OUTP and OUTN. An optional voltage applied to VLVL provides a common mode reference level to offset OUTP and OUTN above ground.
- The AD8364 is supplied in a 32-lead, 5 mm × 5 mm LFCSP, for the operating temperature of –40°C to +85°C.
