Hello, I have a problem designing a power amplifier using the HMC413 chip. The circuit is built with reference to the data sheet, but when powered on, Vpd is 3.6V, and then Vc is increased from 0 up. The manual recommends 5V, but when it is added to about 1.9V, the current is very large, exceeding the data sheet. The typical value of , and can't be added any higher, which is the reason.
