APPLICATIONS

►Low and medium Earth orbit (LEO/MEO) space payloads ►Geosynchronous Earth orbit (GEO) satellites ►Avionics ►Point-to-point microwave links ►Instrumentation and measurement equipment ►Military radios ►Long-term evolution (LTE), Wi-Fi, WiMAX wireless networks ►RMS power measurement ►Receive and transmit gain control ►RF power amplifier (PA) transmit power control GENERAL DESCRIPTION The RH5596S-CSH is a high accuracy RMS power detector that provides a very wide RF input bandwidth, from 100 MHz up to 40 GHz. This makes the device suitable for a wide range of RF and microwave applications, such as point-to-point microwave links, instrumentation, and power control applications. The DC output-voltage of the detector is an accurate representation of the average signal power applied to the RF input. The response is linear-in-dB with 29 mV/dB logarithmic slope over a 35 dB dynamic range with typically better than ±1 dB accuracy over the full operating temperature range and RF frequency range, from 200 MHz to 30 GHz. In addition, the device’s response has ±1dB flatness within the frequency range of 200 MHz to 30 GHz. The detector is particularly suited for measurement of waveforms with crest factor (CF) as high as 12 dB, and waveforms that exhibit a significant variation of the CF during measurement. To achieve higher accuracy and lower output ripple, the averaging bandwidth can be externally adjusted by a capacitor connected between the FLTR pin and OUT pin. The enable interface switches the device between an active meas- urement mode and a low-power shutdown mode. Additional application and technical information can be found in the Commercial Space Products Program brochure and the LTC5596 data sheet.
