We are using HMC349ALP4CE and requesting Gain, isolation, P1db, IP2,IP3, noise vs frequency for Microwave Office simulations. Pls assist.
I sent you the data with email.
I have a question on this component also.
For Dicke Switch, model 'HMC349ALP4CE', there is a external circuit connect to pin 2 (Vctl) and pin 5 (Enable). The circuit is made of resistors and diodes.
First, we are not sure what this external circuit is used for.
Second, In the datasheet, there is only value for resistors. What should be the type and value of the diode.
Third, pin 1, pin 2 and pin 5 are all connect to VDD. Are these VDD the same? Or for pin 2 and pin 5, VDD is actually the different control voltage which should be refered to the truth table?
Could you also give me answer on it?
The resistors and diodes shown in the interface schematic of Vctl and EN pins are not meant for external connection, they are inside the HMC349ALP4E. Digital control inputs (Vctl and EN) should be externally connected to logic LOW or HIGH for desired switch state per truth table. Logic LOW or HIGH levels for digital control inputs (Vctl and EN) are given in control voltages table.
