HMC336 control logic

Question

HI, 
 HMC336 has no integrated control logic driver. Please help to share the best suited device for generating differential signal generation to control lines of HMC336 for enabling the switching logic. I am trying to implement this using below logic whether it is advisable or not. from below i am going to use -Vs as 0 and +Vs as 5V. Kindly advise. 
 
 Regards, 
 Sai

Hi Sai, 
 Our suggested interface circuit to drive A and B switch inputs from single TTL/CMOS control signal line is below. 
 
 Best.)

Hi Sai, 
 We generally use the 74HCT04 hex inverter for realizing these types of interface circuits requiring logic inverters. 
 I don't think this is a typical application area for ADA4927. 
 Best.

Hi, 
 The HMC336 employs FET devices with a typical threshold voltage of -2.2 V. It has been test at 5V only where it provides provide optimum performance. It could be operated at 3.3V but its large signal performance (P1dB and IP3) is expected to degrade. I hope this helps. 
 Note that the HMC336 is in LTB period and will be obsolete soon. HMC349AMS8G is the recommended replacement (not pin to pin compatible).
