Technical Context

The EVAL-ADF7020-1DBZ8 implements the full ADF7020-1 transceiver reference design using a 48-pin MLF package, external VCO inductors (L1/L2), and matched LNA/PA networks optimized for 315 MHz and 433 MHz bands. It supports both direct-output (135–650 MHz) and divide-by-2 (80–325 MHz) modes with on-board crystal oscillator (3.625–24 MHz), loop filter components, and regulated power domains for analog, digital, and RF sections.

It provides access to all 48 pins via test points and headers, including SLE/SDATA/SCLK serial interface, DATA I/O, INT/LOCK, CLKOUT, ADCIN, and RFOUT/RFIN differential paths. The board includes CREG decoupling (100 nF + 5.1 pF), RSET bias (3.6 kΩ), RLNA (1.1 kΩ), and CVCO noise compensation (22 nF), per ADF7020-1 layout guidelines.
