I have some questions regarding the HMC1099 Power amplifier:
- According the efficiency equation, Eff=P.out/Pin(D.C) ---> leading to [10w/28V*0.1A] X100 =357%. What am I missing?
- The plots on the datasheet page 6 are for Vdd=28 V and I=100mA.
Please explain how can I see the PAE value from the graphs
Please explain where/How can I extract from the graphs the PAE value @ Pout=2W?
- A PA with Pout of up to 4W ( With highest Eff needed at 2W ) and Freq range: 20-530MHz is prefered. Is there such part?
- Is it required to implement a specific power up sequence? If yes, is there such a power device supporting this HMC part? Any application note available?
