LTC5564 UltraFast™ 7ns Response Time 15GHz RF Power Detector with Comparator
FEATURES DESCRIPTION
n Temperature Compensated Schottky RF Peak Detector The LTC®5564 is a precision, RF power detector for ap- n Wide Input Frequency Range: 600MHz to 15GHz† plications in the 600MHz to 15GHz frequency range. The n Wide Input Power Range: –24dBm to 16dBm LTC5564 operates with input power levels from –24dBm n 7ns Typical Response Time to 16dBm. n 75MHz Demodulation Bandwidth A temperature compensated Schottky diode peak detector, n Programmable Gain Settings for Improved Sensitivity gain-selectable operational amplifier, and fast comparator n Adjustable Amplifier Output Offset Voltage are combined in a small 16-lead 3mm × 3mm QFN package. n High Speed Comparator with Latch Enable: 9ns Typical Response Time The RF input signal is peak detected and then sensed by n 16-Lead 3mm × 3mm QFN Package both a comparator and amplifier. The comparator provides n a 9ns response time to input levels exceeding V Temperature Range: –40°C to 125°C REF along with a latch enable/disable function. The gain selectable
APPLICATIONS
operational amplifier provides a 350V/µs slew rate and n 75MHz of demodulation bandwidth to the analog output. RF Signal Presence Detectors for: 802.11a, 802.11b, 802.11g, 802.15, Optical Data Links, Wireless Data VOUTADJ and VREF pins allow for the adjustment of VOUT Modems, Wireless and Cable Infrastructure offset and VCOMP switch point voltages, respectively. n 5.8GHz ISM Band Radios L, LT, LTC, LTM, Linear Technology and the Linear logo are registered trademarks and n UltraFast is a trademark of Linear Technology Corporation. All other trademarks are the property MMDS Microwave Links of their respective owners. n PA Power Supply Envelope Tracking Control †Higher frequency operation is achievable with reduced performance.
