RF detector solution

17 September 2008 Telecoms, Datacoms, Wireless, IoT

Analog Devices (AD) has introduced RF (radio frequency) detector products for RF and analog engineers who need to improve power detection performance while simplifying the design of cellular handsets, wireless infrastructure equipment and communications instrumentation.

The ADL5502 is an integrated crest-factor RF power detection IC and combines an rms (root mean square) RF detector and an envelope detector to enable designers to manage wireless handset power more efficiently, extend battery life and better process complex 3G and emerging 4G cellphone signals. It features ±0,1 dB accuracy with crest factors up to 11 dBm, and provides ±0,2 dB temperature stability from –40°C to +85°C, further reducing calibration routines while allowing handsets to operate more reliably over temperature.

AD is also introducing the ADL5513 log amp (logarithmic amplifier), which provides RF engineers with a wide dynamic range (80dB with ±3 dB log conformance up to 4 GHz) to help them to accurately detect and control output power up to WiMAX and LTE (long-term evolution) frequency bands. It drifts less than ±0,5 dB over temperature, simplifying system calibration routines by enabling designers to use only a room-temperature calibration, and operates to 125°C.
