4.1 Example AMM-6702CH Application Circuit

Below is an example application circuit for the AMM-6702CH. It is particularly important to use sufficient external capacitance on the Vd pads to prevent potential feedback oscillations from occurring. We have found that adding some small (10 Ω) shunt resistance as shown in the application circuit diagram creates very reliable operation. Since the amplifier IC has very high gain, it is possible for positive radiative feedback to occur between the wire bonds on the RF traces and the power supply network. We have observed that the most effective ways to protect against radiative feedback oscillations is to epoxy ferritic absorber material near the input and output traces and to avoid mounting the chip inside of an extremely small cavity. Email support@markimicrowave.com for any additional questions and assistance in avoiding oscillations in the AMM-6702CH in your specific application. The AMM-6702 has a potential oscillation if driven between -10 dBm and -8 dBm with a frequency between 22 GHz and 27 GHz with a Vd higher than 3.3V. If your application or frequency plan requires this specific condition, we advise that the user either reduce Vd or add an attenuator or pre-driver to the input to change the input power presented to the amplifier. The most stable condition to run this amplifier is in compression with at least 0 dBm to 5 dBm of input power.
