Hello All,

 

ADRF6620 has 5V DC Pins (Pin No. 1, 12, 13, 14, 24), my customer wants to save the power by disconnecting the supply voltage.

If customer wants to use only Mixer, is it possible to disconnect VCC2, 3, 4, 5 pins from 5VDC Power?

or Do we must supply 5VDC all 5pins?

 

According to the datasheet from Table 14. Basic Connections, It stated below.

Pin 01: VCC1 - LO,VCO, mixer power supply

Pin 12: VCC2 - IF DGA power supply

Pin 13: VCC3 - Factory calibration pin

Pin 14: VCC4 - Factory calibration pin

Pin 24: VCC5 – RF front-end power supply

 

Thank you and best regards,
