Product Overview

ADRF6821 is a highly integrated, dual radio frequency (RF) input, zero intermediate frequency (IF)/low IF RFIC receiver with a quadrature demodulator, digital step attenuator (DSA), IF linear amplifiers, an integrated, fractional-N phase-locked loop (PLL), and a low phase noise, multicore, voltage controlled oscillator (VCO). The RFIC is ideally suited for communication digital predistortion (DPD) systems. The high isolation 2:1RF switch and on-chip wideband RF balun enable the device to support two single-ended, 50 ohm terminated RF inputs. A programmable attenuator ensures an optimal differential RF input level to the high linearity demodulator core. The integrated attenuator offers an attenuation range of 15dB with a step size of 1dB. It is used in application like cellular W CDMA/GSM/LTE, DPD receivers, microwave, point to point radios etc.
  • DPD receiver with integrated fractional-N PLL
  • RF input frequency range is 450MHz to 2800MHz
  • Internal LO input frequency range is 450MHz to 2800MHz
  • Dual RF inputs with SPDT absorptive RF switches
  • Integrated VCO to cover complete RF input range
  • Digital programmable LO phase offset and dc nulling
  • Programmable via 4-wire SPI
  • Operating temperature is -40°C to +105°C
  • Package style is 56-lead lead frame chip scale [LFCSP]
