APPLICATIONS Multiband/multistandard cellular base station receivers Wideband radio link diversity downconverters Multimode cellular extenders and broadband receivers www.DataSheet.co.kr GENERAL DESCRIPTION The ADL5811 uses revolutionary new broadband, square wave limiting, local oscillator (LO) amplifiers to achieve an unprecedented radio frequency (RF) bandwidth of 700 MHz to 2800 MHz. Unlike conventional narrow-band sine wave LO amplifier solutions, this permits the LO to be applied either above or below the RF input over an extrem...
