Key Features

  • Dual voltage-controlled oscillators (VCOs) with internal and external inductor options, allowing dual-band operation and frequency hopping spread spectrum (FHSS) capabilities.
  • Support for 2FSK, 3FSK, and 4FSK modulation schemes with programmable frequency deviation and data filtering options (Gaussian and raised cosine filters).
  • Low IF architecture with programmable IF bandwidths to minimize power consumption and external component count.
  • Automatic frequency control (AFC) loop with programmable pull-in range and image rejection performance of 56 dB using a patent-pending IR calibration scheme.
  • On-chip ADC for temperature sensor, external analog input, battery voltage, and RSSI signal readback.
  • Programmable transmitter output power in 63 steps and automatic power ramp control to prevent spectral splatter.
  • Simple 3-wire interface for RF frequency and modulation programming.

Applications

The ADF7021BCPZ-RL is suitable for a variety of wireless connectivity applications, including:

  • Narrow-band, license-free ISM bands.
  • Licensed frequency bands.
  • Wireless sensor networks.
  • Industrial control systems.
  • Remote meter reading and smart grid applications.
