Signal generator for RF energy solutions

The product provides an all-in-one solution for the small signal generation in the RF energy solutions such as cooking and lighting markets.

The product facilitates RF energy design by:

  • Allowing on-board integration
  • Providing flexibility in system solution development

Features and benefits

  • Support from 2400 MHz to 2483.5 MHz, from 902 MHz to 928 MHz and from 433 MHz to 434.8 MHz ISM bands
  • Single 3.3 V supply voltage
  • SPI-bus interface up to 20 MHz
  • Fully integrated LC-VCO operating in the range from 6.6 GHz to 10 GHz and used with a Σ∆ PLL to generate the frequency
  • Very fast tuning and hopping time PLL
  • High frequency daisy chaining allowing coherent excitation of multiple RF amplifier chains
  • 360° phase shifter with 1.4° steps
  • Medium Power Amplifier (MPA) delivering an output up to +27 dBm peak power (max. +24 dBm for continuous use)
  • Low Power Amplifier (PPA) delivering an output up to +7 dBm
  • Integrated 20 dB gain control
  • Integrated RF switch allowing PWM control
  • Temperature sensor indicates the junction temperature of the die
  • RoHS compliant

Applications

  • Solid-state cooking
  • Solid-state lighting
