Power supply requirements for VDD and Control Voltage for HMC8038

Maxplus on Sep 9, 2020

Hello,

We are using the HMC8038 RF Switch Evaluation board in a concept to switch between TX/RX to Antenna.

For Supply and Control voltages to the HMC8038, we are tapping off the +5V supply from HMC981 Bias controller for a HMC8410 LNA device.

What are the power supply and control voltage requirements for HMC8038 RF Switch please?

Hi,

For 5V Vdd, the required current is 0.16mA and for digital control voltages, <1uA. Vdd can have tolerance of +-5%
