Description
VCO Input Pin. The tuning voltage on this pin determines the output frequency of the voltage controlled
oscillator (VCO). The higher the tuning voltage, the higher the output frequency.
Regulator Voltage for PA Block. A 100 nF in parallel with a 5.1 pF capacitor should be placed between this pin
and ground for regulator stability and noise rejection.
Voltage Supply for PA Block. Decoupling capacitors of 0.1 μF and 10 pF should be placed as close as possible to
this pin. All V
PA Output Pin. The modulated signal is available at this pin. Output power levels are from −20 dBm to +13 dBm.
The output should be impedance matched to the desired load using suitable components. See the Transmitter
section.
Ground for Output Stage of Transmitter. All GND pins should be tied together.
LNA Input for Receiver Section. Input matching is required between the antenna and the differential LNA input
to ensure maximum power transfer. See the LNA/PA Matching section.
Complementary LNA Input. See the LNA/PA Matching section.
External Bias Resistor for LNA. Optimum resistor is 1.1 kΩ with 5% tolerance.
Voltage Supply for LNA/MIXER Block. This pin should be decoupled to ground with a 10 nF capacitor.
External Resistor to Set Charge Pump Current and Some Internal Bias Currents. Use 3.6 kΩ with 5% tolerance.
Regulator Voltage for LNA/MIXER Block. A 100 nF capacitor should be placed between this pin and GND for
regulator stability and noise rejection.
Ground for LNA/MIXER Block.
Signal Chain Test Pins. These pins are high impedance under normal conditions and should be left
unconnected.
Ground for LNA/MIXER Block.
Signal Chain Test Pins. These pins are high impedance under normal conditions and should be left
unconnected.
Chip Enable. Bringing CE low puts the ADF7020-1 into complete power-down. Register values are lost when CE
is low, and the part must be reprogrammed once CE is brought high.
Load Enable, CMOS Input. When LE goes high, the data stored in the shift registers is loaded into one of the
four latches. A latch is selected using the control bits.
Serial Data Input. The serial data is loaded MSB first, with the 2 LSBs as the control bits. This pin is a high
impedance CMOS input.
